Although their name may suggest otherwise, perennial beds and borders do change with time. Every few years they need to be reevaluated. Plants may need to be moved to a different location where they will either look or grow better. A great number of perennials (at least the ones I grow) benefit from division. Perhaps those trees nearby have extended their branches enough to alter the amount of sunlight now available. Or maybe you lost part or all of a shade tree in last year’s wind storms. Maybe that cute little 4-inch pot of doronicum you planted has laid claim to more than its fair share of the garden. Even your tastes in colors, design ideas or seasons of bloom may have changed. Whatever the reason, spring is a good time to overhaul the perennial garden.

Before you begin to pick up that spade and begin digging, you need to decide on the type of look you are aiming for. Your site conditions will likely dictate your choice of plant material. Try as you might, perennials like gaillardia, lavender and dianthus will not do well in soggy soils, while hellebores will wither away in hot, dry exposed sites. Consult one of the many splendid books or websites on perennials, talk to a knowledgeable person at a local garden center, or give us a call if you are in doubt about a plant’s cultural requirements.

Another factor to consider is the maintenance many perennials require for their best display. Delphiniums in all but the most sheltered areas need to be staked. Yarrows and evening primroses should be divided every couple of years. Garden phlox must be religiously deadheaded so its usually magenta colored progeny do not take over the world. Lilies need the once over just about every day to patrol for lily leaf beetles. And, some plants like columbine, rudbeckia and agastache just seem to have relatively short life spans, at least in my yard, and require regular replacement whether through self-seeding or store purchase. I don’t believe a plant exists that does not require at least occasional attention but if you are limited in the amount of time you have to deadhead, stake, divide, and control pests, you will definitely want to choose less demanding perennial species.

When redoing your perennial beds, keep in mind also the season of bloom. Many perennials, for all their loveliness, have a tendency to bloom over a short 3 to 6-week span of time. A few will provide color, or at least interest from early summer until frost. These include plants like hostas, coral bells, Russian sage, and some dwarf daylily cultivars. Some gardeners strive for a riot of color for mainly one time period, say the month of June, while others prefer smaller portions of color that extend over the whole growing season. Spring flowering bulbs and annuals can provide interest either by complementing the flowers of perennials or as fillers when little else is blooming.

Spring is generally a great time to divide mid and late season flowering perennials with the early fall being better suited for the early spring bloomers. If you cannot replant the divisions immediately, pot them up, or heel them in somewhere not in full sun. Perennials with a long tap root like baby’s breath and echinops do not appreciate being moved so place them carefully. Asters and some others in the composite family tend to die out in the center. Just transplant the new growth surrounding it and discard the woody middle part. If you need to move Oriental poppies, wait until they go dormant, usually in July or August.

Asters multiply quickly and benefit from division every 3 years or so. Photo by dmp2012.

Think about what bulbs you might like to see blooming with your early season perennials and make a note to purchase them for fall planting. Place the bulbs behind sprawling perennials so that the dying bulb foliage will be camouflaged.

Don’t be afraid to experiment and, most of all, don’t be afraid to rectify any unsatisfactory plantings. Unlike, permanent tree and shrub plantings, a perennial garden can be modified to suit your needs and desires.

Happy Spring!

Shamrocks are the official plant of St. Patricks Day symbolizing the country of Ireland. History and folklore state St. Patrick used the three-leaved plant to explain the concept of God being three in one: father, son and holy spirit. He used Ireland’s native clover(Trifolium repens) commonly called shamrock to give a visual to the idea for the spreading of Christianity. Today a similar shamrock-looking plant, Oxalis, is sold as ornamental houseplants to celebrate the holiday, adding a bit of the green to our homes when it is sorely needed at the end of winter.

Plant breeders have even found a way to add a little purple in this ‘shamrock’ plant for sale at the local grocery store. I wonder what St. Patrick would think!

White clover (Trifolium repens), has become a widespread common lawn weed in the United States. Normally it has only three leaves, but occasionally the plant produces a fourth leaf proclaiming to provide luck to its finder. Many a child has spent a busy afternoon searching for their own four leaved clover to press between the pages of a book to preserve it. Clover is a fascinating plant in the legume or pea family Fabaceae which takes nitrogen from the air and deposits it in nodules on the roots. When the plant dies and breaks down naturally, the nitrogen is slowly released for other nearby plants to use. Clover is great for building soil nutrients and adding a bit of luck to your garden or lawn.

Oxalis stricta, photo from

Oxalis or yellow woodsorrel (Oxalis stricta), is another lawn weed reminiscent of shamrocks with its trifoliate leaves. It is the wild cousin of the well-bred Oxalis houseplants. This one has yellow flowers rather than the white, and is a native annual that sometimes lives through a mild winter.

I wish you luck in finding your shamrocks on this St Patrick’s Day!

This winter started off warmer than usual, settled down to a white and cold normal one, and now it seems to be in a hurry to get as warm as possible before April can get all the credit for bringing in the welcome green of spring. By the end of the month spicebush may be blooming and perhaps the marsh marigold.

Marsh marigolds (Caltha palustris) are one of the first wildflowers to bloom and the plant is very conspicuous as it grows in swamps, along streambanks, and sometimes directly in the water in wet woodland habitats. There may be no leaves on other plants yet, and  brown leaf litter may cover the ground, but the splash of bright green highlighted with yellow flowers is a welcome herald of what will come.

Birds have been singing their morning and evening songs, plus their territorial daytime calls as well. Male turkeys have begun their strutting, hissing and stamping routines which are somehow alluring to the hens.

Bald eagles have built a nest in my town, and the pair have been seen sitting together along busy roads where they have chosen to raise their young. A nearby open river has provided food for them all winter, and the high traffic volume and large number of people watching this pair does not seem to bother them at all.

Killdeer, one of our first birds to return from their winter vacation homes have been back since late February this year. The early bird gets the worm… They lay their eggs directly on the ground in open gravelly areas and their young are born covered with down and ready to run around with the parents.


Like the killdeer, blackbirds and grackles have been back since late February, but wait until females arrive a month or so later to breed. They can be seen together in large flocks where seeds are abundant.

While hiking in the woods, my sister and I came across some peculiar damage to quite a few mature trees in a widespread area. Bark had been scratched and clawed off, sometimes shredded, and areas damaged were about three feet off the ground. This was the work of a black bear, new to this particular area and now residing in the woods by the looks of it. Marking trees with teeth and claws, especially in  spring is thought to either mark territory or just be from normal stretching and scratching activity.

Along the shore ruddy ducks usually can be seen floating in large groups along the in Old Saybrook causeway. These cute little ducks can be recognized by their small size, blue bills of the males, and the perky little tails that are sometimes held straight up. Sometimes little coots can also be seen along the Connecticut shoreline now.

Sweet ferns Comptonia peregrina, a native shrub with aromatic foliage, is showing its flower buds unfurling at this time of year, and  some of our pussy willows are almost blooming. I have a black pussy willow that is almost in full bloom, and that is a sign that Collettes inaequalis, a small, handsome, native ground-nesting bee, will be out and about soon.

I can hardly wait for green to be the primary color in the landscape again, and I strongly share this person’s sentiment:

Veteran houseplant owners and novices to indoor gardening alike, have most likely, at one time or another, experienced the plague that is a fungus gnat infestation. These tiny insects begin their lifecycle in the potting media of houseplants that have been consistently overwatered. Once established, fungus gnats multiply quickly, with populations usually localized to a certain plant, or group of plants.

This insect is not known for causing excessive damage to the plants themselves, fungus gnats are more annoying and unsightly than they are damaging. However, the larvae feed on organic material found in the potting media, which can sometimes include the roots. Another reason root damage is less likely is because fungus gnat larvae reside in the top 2-3” of the soil. These insects are attracted to moisture as that is where they lay their eggs. It is not uncommon for fungus gnats to attempt to fly into your mouth. Anyone who has experienced this knows that fungus gnats are not something you want to leave unchecked in the home.

Controlling moisture is key to controlling fungus gnats. Populations are most abundant when there is an overabundance of moisture in the area, usually this is caused by overwatering. Over saturated media is the perfect egg laying habitat for this pest. Managing your irrigation goes a long way towards managing this pest, letting soils get as dry as possible before watering is a highly effective yet simple control method. It is important to note, this technique can be damaging to some plant species that may require consistent moisture in their growing media. If that is the case there are other options for control. Bottom watering just enough so that the bulk of the root ball is wet but the top of the soil remains dry is also effective. This can be tricky and requires some experimentation to get right.

A popular method for monitoring as well as controlling fungus gnats and other flying insects is the use of yellow sticky cards. Insects are attracted to the bright yellow color and are then entangled once they land on the trap. I use these in my houseplants even when I don’t have a sever problem as they let me know what insects are present just by looking at what’s stuck to the trap. Adding these traps to an already established infestation will help reduce the  breeding population of flying adults. There area also chemical controls available for this pest in the form of pellets which are placed on top of the potting media. Bacillus thuringensis var. Israeliensis is a strain of bacteria that is also effective at controlling gnats and can be applied to the soil via drenching. Ensure that any chemical controls being applied are labeled for fungus gnats and that you follow manufacturer’s directions for indoor home use.

Vegetable gardening is very popular these days, and even more so since the COVID outbreak.    Anyone new to this hobby is quick to hear some terms being thrown around when describing different types of vegetables. Knowing the meaning of these terms gives prospective gardeners some key information that helps them pick varieties of vegetables most suited to their needs. All living creatures, known to man, are classified according to species and genus. So for instance, all tomatoes are classified as Solanum lycospersicum.  

To start off, I already used the term “variety”. This term is used rather loosely in horticulture and is incorrectly interchanged with “cultivar”. Both refer to the differences in the species of plant you have chosen. Varieties refer to naturally occurring deviations from the original species. They typically come true to seed. Cultivars have been purposely cross-bred from two or more different species. Plants must be either vegetatively propagated or started from hybrid seed each year. These varieties or cultivars have names and are associated with specific characteristics.  For example when I say “Sweet Millions” tomatoes, a person familiar with this cultivar knows that they are cherry tomatoes, indeterminate, very flavorful, and highly productive. For the sake of this article, I will stick with tomato examples, but these terms could apply to many vegetable species and cultivars.

Our tomato plants contain both male and female flower parts. Because of this, they are easily pollinated by wind or bees. This is problematic for greenhouse tomato growers, so they will hand pollinate the tomatoes with paint brushes or even special electronic devices that shake the flower to accomplish pollination. Fortunately for us outdoor gardeners, we do not need to do anything special for pollination to occur.

Probably the best place to start is talking about “open pollination.” This is essentially how Mother Nature does things. There is a large population of organisms that have genes for individual traits, or characteristics. If we stick with our tomato example, think of: size, color, growth habit, disease resistance, plant height, etc. In my example, the population of tomatoes living in the wild in a certain area would have a lot of genetic diversity. As we all have experienced, the weather can vary from year to year. Genetic diversity in the population is nature’s way of ensuring that some organisms will survive and reproduce. Likewise, different parts of the country (or the world) will have different weather, climates, and microclimates.  Certain traits or characteristics are an advantage or a disadvantage depending on where you are living.  Over time, a population of tomatoes will see an increase in the genes that help it survive in the local environments. These would be considered different varieties of tomatoes.   

Some growers like to have open pollinated plants. They see which tomatoes produce the best and then save seeds from those plants to be planted the following year. In this way, the gardener is essentially developing a variety of tomato that is perfectly suited to living, growing, and even thriving in that particular area of the world. In addition, the gardener may also select for certain traits he or she prefers, like low acid, yellow tomatoes for example. Over time, the gardener may select and replant only the seeds of the plants that conform to certain pre-determined criteria.  Eventually the plants will breed true, or have the same set of characteristics, year to year.

This little cherry tomato was not planted by the gardener. It came from last year’s hybrid varieties. If desired, seeds could be saved and a new variety selected over time. Photo by mrl2020.

For the next term, I would like you to think of a young man that proposes to his girlfriend and while doing so presents her with his Grandma’s diamond ring. This piece of jewelry was passed down through the generations in his family. We call this ring an heirloom. Well there can be heirloom plants as well. These are varieties that have a specific set of characteristics and have a documented history. One of my favorite examples is the Brandywine tomato. This variety dates back to the late 1800s, and is noted for its exceptionally unique flavor, reddish pink coloration, and potato-shaped leaves. Heirloom varieties are open pollinated as well. What sets them apart from regular open-pollinated varieties is their documented history of being passed down through the generations, by name, with those specific characteristics. Many people fall in love with the idea of planting something so “valuable” that has been passed down through the generations.  Unfortunately, many of the heirlooms are not disease resistant and have a hard time growing in our modern world. Growing in containers with soilless media or in new planting areas are best suited to heirloom plantings. As long as there was no cross pollination (closely planted varieties of the same plant or active bees could do this), you should be able to save the seeds and get the same variety the following year.

This brings us to the next name to learn, and that is “hybrid”. A hybrid variety is formed by crossing two specific parent types. These parent varieties are usually kept secret. This produces a certain set of characteristics in the offspring. Examples include ‘Big Beef Hybrid’, ‘Better Boy Hybrid’, ‘Lemon Boy Hybrid’, etc. These can be particularly useful, and have specific qualities for which a gardener is looking. A gardener must pick carefully, as some of these hybrids are selected to transport well, delay ripening, or some other trait desirable for commercial production but not the fresh picked home-grown experience. The big advantage of hybrid tomatoes is the disease resistance they can have, although not all hybrids have the same disease resistance profile. I prefer to patronize companies that describe the disease resistant characteristics of the hybrid seeds I am purchasing. The downside to growing hybrids is that if you save the seeds and replant the following year, they will look nothing like the parent plants! They essentially would be like starting with an open pollinated version year one and it could take many, many years to get a tomato that breeds true (has a consistent set of characteristics from generation to generation).  Some people do not like to use hybrid seed as it forces you to buy new seed from the seed company each year. Others believe it is a small price to pay for disease resistance and known characteristics one can count on. Knowing the specific attributes of the plants before planting can be highly important for the home gardener and commercial grower alike.

The next type of tomatoes has been used by commercial field and greenhouse growers for years.  Within the past ten years or so they made their way into the retail markets. These are “grafted” tomatoes. The grafting process goes back for many thousands of years for various reasons depending on the crop species. For tomatoes, simply put, we cut the above ground portion off and stick it onto the root stock of another variety. This can be done with our heirlooms. The top portion retains the qualities of taste, color, and style while the bottom root portion of a different variety, attribute’s resistance to many soil borne pathogens. The reason these have not really caught on too well in the retail market is the price. There is a lot of labor involved with this process, and for every one plant you sell you actually have to grow two plants (one for the top, and one for the roots). While a packet of thirty seeds or four plants may sell for three or four dollars, a single grafted plant of the same variety can sell anywhere from eight to thirteen dollars.  This is assuming you can find what you are looking for locally as none of those prices include shipping!

The final topic I wanted to cover was Genetically Modified Organisms, or GMOs.  These organisms have had their genetic material altered in a way that is not natural. Normally, we get new gene combinations through egg and sperm formation and the resultant reproductive event that follows. With genetic modification, genes can be altered, removed, or added in. Scientists can also cross genes from different species of plants or animals. Plant hybridizers have been crossing closely related, but nonetheless different, species for centuries. As such, the public is generally not as resistant to this “more natural” activity. For example, you can cross two different species of Echinacea coneflower in order to create a new color variety. Where the public gets worried, is when a gene from a distantly related organisms is inserted into the genome of another. For example, Glofish were made by inserting a gene from a coral into a fish.  There is no realistic way that would happen in nature. Due to the fears described above, there are currently no GMO tomatoes being sold on the market. This is not due to any known hazard to humans, but rather due to the public being wary of a technology that is new, by a process unknown to many, and not having enough time to see what will happen with these “experiments” long-term. There are, however, many other examples of vegetables that are GMO, like soybeans some corn, and canola for example.

So given all this information, what category of vegetable do you pick? Well, the simple answer is that it depends on what you want to do, and how good you are as a gardener. For anyone new to the endeavor and looking to plant tomatoes, I would recommend starting off with the disease resistant hybrids. These are generally the most forgiving. Once you have a good idea of how to grow the plants, maybe you would want to try an heirloom variety or two in addition to your regular stock. Open pollinated plants can be fun as well as you can save your seeds each year and select for certain traits, but you need patience and time. This gives you the power to essentially create something new and unique suited to your specific needs or desires. No matter what you decide, get out there and plant! As I always suggest, get a soil test first for best results!

According to language of flowers so popular during the 1800’s, the violet represents modesty and decency, qualities sorely lacking in modern society some would argue. There may be 500 or more species of violets as not only does this family include sweet violets, bedding violas and pansies but its members are naturally rather promiscuous and have also been crossed by breeders. Violets are mostly native to temperate Northern Hemisphere regions and the ones most commonly found in our yards probably originated in Europe.

Pansies by Lisa Rivers

Most violets are small perennial plants although some are annuals. Small clumps of heart to kidney-shaped leaves grow from compact stoloniferous rootstocks.  Half-inch flowers may be purple, bluish, white, yellow, pink, maroon, bicolored or speckled. Solitary flowers arise from leaf axils in April and May and consist of 5 sepals and 5 petals.

Violet flowers are rather curious. We notice the flowers above ground but there are also hidden flowers beneath the soil surface of several species that never open but self-pollinate and produce fertile seeds in large numbers. These flowers are called cleistogamous flowers and they are why we often find so many violet seedlings each year surrounding our established plants. The seeds may be ejected several feet away from the parent plant as well which explains why violets can so easily spread throughout a lawn area.

Not all violets are fragrant although the ones that are can take me back to my younger days helping Grandma gather bouquets of sweet violets (Viola odorata) from her garden. The most common blue violet (V. sororia) which spreads vigorously throughout my gardens and lawn, and probably yours as well, has no scent that I can detect.  

Lore and legends surrounding violets go back at least to the times of the ancient Greeks when Zeus turned his lover, Io, into a heifer to protect her from the jealous Hera. He provided her with pastures filled with violets to feast on. The flower was, at one time, a symbol for Athens.

Violets were also a love token between Napoleon and his empress Josephine and later became his political emblem. During troubadour times in Toulouse, France, they were given as a poetry prize and in the Middle Ages in southern Germany, discovery of the first violets of spring was celebrated in dance.

Ancient herbalists Herodotus and Pliny ascribed medical virtues to violets, and they were recommended for gout and spleen disorders and in later times used to treat respiratory disorders. The leaves and flowers were found to have both antiseptic and expectorant properties. Flowers also contain vitamins A and C as well as some antioxidants.

The flowers of the sweet violet (V. odorata) are edible and have been used for garnishes and in salads, jams, jellies, liqueurs and baked goods. They are often candied and used as decorations on cakes, chocolates and other sweets. Other species are edible as well but be sure to positively identify plants before consuming. 

Candied violas from

Violet water is made by weighing down and steeping violet leaves and flowers in water. The softly fragrant water is used in cooking to flavor tea breads, fruit compotes, chilled soups, ices and cupcakes. Both violet water and candied violets can be purchased. 

For a long time, violets were prized for their aromatic qualities. They were widely used in perfumes until the advent of synthetic fragrances. There are still some perfumes made from violets, but it may take a bit of searching to locate them.

Typically, violets prefer somewhat moist and shaded areas, but I have found them growing in garden beds in full sun which get little supplemental irrigation. Our common blue violet along with its white and hybridized relatives such as ‘Freckles’ are tough plants and compete well in the Northeast. I find that they are easier to dig up from unwanted areas in my garden then to get rid of in a lawn. Personally, I find a lawn awash in purple and white quite a lovely spring sight.

Many Connecticut residents are aware that pollinating insects are declining in numbers because of several factors including pesticide use, loss of habitat and climate change. Violets are a pollinator plant because the larvae of several butterfly species including the large yellow underwing and the silver bordered fritillary as well as the giant leopard moth and the Setaceous Hebrew character moth feed on violets. 

In general, violets need little care in terms of watering or fertilizing. Occasionally rabbits will nibble on the foliage, but it always grows back. Enjoy their short-lived blooms and consider using them as a groundcover under deciduous trees where turf grasses struggle.

Wintertime brings more cut flower arrangements into my home. I need to have flowers inside when it is too cold to grow them outdoors. Flowers are used to communicate. ‘I love you’, ‘I’m sorry’, ‘Get well’ and ‘Thank you’, are all sentiments conveyed through flowers. Birthday, anniversary, and holiday arrangements help to celebrate special occasions. Extending the life of the bouquets makes the celebration continue. It is always a disappointment when the first rose head begins to nod like a broken bobble head dog in the back window of a car. Trying to prop up the blossom never works so removal ensues with rearrangement of the remaining blooms and greenery in a hopeful attempt to prolong the dying process. What can be done to eliminate or diminish the natural decomposition process of the bouquet? There are a number of steps you can take.

Lots of beautiful flowers to chose from. Photo by dmp2021

First, flower selection is important. Buy fresh flowers and they will naturally last longer. Shorter time spent in the florist’s bucket means longer time in your home. Whether purchased in the grocery store or flower shop, smell the water in the holding container. If it smells at all, then bacteria have begun to grow. Bacteria equal deterioration to a cut flower. Fungus, yeasts, and algae can also grow in the vase water. Flower stems have cells that move water up by capillary action, a constant pull upward towards the blossom. Bacteria and other organisms clog these cells restricting the uptake of water resulting in wilted flowers. Start with a clean vase. Remove any leaves from stems that would sit below the water surface to lessen areas for the organisms to feed and reproduce. Change the water every two days to reduce colonies of bacteria available to be sucked up the flower stem.

Air bubbles are another detriment to water uptake. If the flow of water it not continuous but interrupted by an air bubble, water flow will stop. Once home, cut the stems of the flowers under running water or in a sink or container filled with water with a sharp, non-serrated knife or scissors. Enough water will cling to the 45-degree angled cut while you quickly place it in the water filled vase to secure a continuous flow of water. Use warm water (110 degrees) in the vase to encourage faster movement up the stem. Enough water will cling to the cut surfaces during water vase changes so re-cutting of stems is usually not necessary. Never let the water level fall below the bottom of the stems.

Placing additives in the water is a common practice for cut flower arrangements. The commercial floral preservatives often distributed with purchased flowers are meant to be a vase water additive. They contain a sugar to feed the flower, a biocide that kills bacteria, fungi and yeasts that feed on the decomposing greenery and sap that seeps from flower stem, and an acidifier. The acidifier lowers the pH of the vase water retarding bacteria, fungi and yeast growth and also help move the water up the stems.

Use the floral preservative provided for longer vase life. Photo by dmp2021

Some home treatments of vase water are said to work on the same chemical principles as the commercial preservatives. A 1/4 teaspoon of bleach per quart of water will act as a disinfectant to kill the bacteria and algae. One tablespoon of sugar acts as a food source. A penny contains copper which is a fungicide. To create an acidic condition in the water, add one aspirin tablet or two tablespoons of lemon juice or vinegar to one quart of water. Non-diet lemon-lime soda will add sugar and create acidic conditions when added to water. Use one part lemon-lime soda to two parts water. Keep in mind, however, that it is generally easier, cheaper and more effective just to use the floral preservative that comes with your flowers.

If possible, consider storing your arrangements in a cool place or even a refrigerator when they are not on display. Temperatures between 33 and 36 degrees F will keep many cut flowers fresher longer. However, if your arrangement contains tropical blossoms like heliconia, bird of paradise or ginger, temperatures should not fall below 50 F.

Vector set tropical flowers. Jungle exotic strelitzia, anthurium, hibiscus, plumeria, orchid and ginger flower.

Keep arrangements away from ripening fruit which releases ethylene gas that will age flowers faster. Place bouquets out of direct sunlight and out of drafts. Use lukewarm water for most flowers but cold water for bulb flowers like daffodils, tulips and hyacinths. Flowers that release a milky sap from the stem when cut benefit from sealing by passing the cut stem ends over an open flame or dipping the cut ends into boiling water for 20 seconds. This stops the stems from oozing. Some flowers naturally have a longer vase life than others including alstroemeria, aster, celosia, cosmos, gypsophila, lavatera, rudbeckia, scabiosa, snapdragon, statice, sunflower, yarrow and zinnia. Hollow stem flowers wilt the quickest.

So as these long days of winter leave you longing for summer, head to the flower shop armed with all this information to make the beauty of cut flower arrangements last a long time in your home.

Here’s to an early spring!

Getting outside in the winter can take some serious nudging if the cold is a factor, but when prodding has done its work, expect to find things of interest as you walk, hike or even drive along. A backyard or a hiking trail can provide more interesting viewing than television programs offer and things we see will probably pique our curiosity as well.  

Cladonia arbuscula lichen

Cladonia arbuscula is a fruticose lichen, that is, its shape resembles a tiny shrub. Highly branched, it occurs on the ground in open acidic areas, sometimes forming large areas of tufted mats. It is one of many lichens commonly referred to as reindeer lichens. It is light gray-green or cream and has a puffy appearance.

Princess pine, Lycopodium obscurum, a flat-branched species of club moss, is a  common forest understory plant  of North America. It is actually neither a low- growing conifer nor a moss but is instead  closely related to ferns and horsetails. They have green scale-like leaves and yellow to tan sporophylls on branch tips that produce spores.

Sometimes when hiking in New England woods you come across stone walls. In the past, these were probably erected as borders along the edge of woods on farmland. Over the years, as farms are abandoned or fields are no longer cultivated, the land cleared for fields has returned its original woodland habitat. Robert Thorson, a landscape geologist at the University of Connecticut, estimates that there are more than 100,000 miles of these old stone walls which could circle the globe 4 times.

On a recent trip to the shoreline in Old Lyme, right after a strong winter storm, there were tons (probably!) of shells washed up above the normal high-tide mark. If you find a tan, spiral string of cases, check this out. These are the egg casings of a whelk and contain a bunch of tiny whelks in each case. Sometimes people open one up and think it is just sand inside, but if you look carefully you may see any remaining whelks inside.

Broomsedge bluestem Andorpogon virginicus is a native grass that turns bright orange in late fall and remains upright throughout much of the winter season, often standing tall above snow cover. Seeds are a source of food for birds and small animals. This plant also supports various Skipper butterfly larva and small butterflies obtain nectar from the flowers.

Telling the difference between red and pitch pines has become easier as I have learned that red pine needles are in bundles of two, and pitch pine needles are in bundles of three, and are often twisted. Red pine has smaller cones and lack the stout spines on individual scales that characterizes those of pitch pines. Also, red pine bark peels away on upper trunk and branches revealing a nice red color.

Other things I came across recently include melted snow where deer had bedded down, a red-shouldered hawk in the neighborhood and a Cooper’s hawk perched on a dead tree looking for prey, a trunk of a small tree damaged by a deer rubbing its antlers, interesting cloud formations and a Promethea moth cocoon dangling from a spicebush twig. As my nephew, Ben, once stated when observing nature as a small boy, “the excitement never ends”.

The reasons for providing artificial light for your indoor plants can vary greatly depending on what you’d like to grow. Sometimes a light source is provided temporarily to help a plant get through the winter or to give seedlings a head start before spring plantings. Other times artificial light is added to create a permanent growing environment for ornamental houseplants or indoor crops such as microgreens and hydroponically grown vegetables. Lighting technology has come a long way in the past few years, enabling hobbyists and professionals to get even more out of their light source than ever before, often at an affordable price and reasonable rate of energy consumption. Listed below are the most common types of light used for indoor plantings along with some considerations for each type. Choosing grow lights is not a one size fits all scenario and selecting the right one can be a daunting task; use the information below to help make a more informed decision before making the investment.

One of the first things to consider is whether or not, a grow light is actually necessary to achieve the desired outcome. Being able to recognize the symptoms of insufficient lighting will help determine if adding artificial light is the right decision. Some of the symptoms that you  may begin to see when plants are not given enough light include: stretching, loss of lower or even all leaves, slowed growth, diminishing leaf size as the plant grows, and chlorosis or yellowing of the leaf surface. Seedlings that are straining to reach for more light will flop over as they grow overly tall. Plants that are not photosynthesizing will use little to no water, causing them to sit in wet media for too long, resulting in root health issues. Conversely, too much light can result in burning of the leaf and stem. This is something that typically occurs when a high-powered grow light is added to a space without first acclimating the plants. When a new light source is added, monitor for symptoms of burning and add light incrementally if possible, either by using a dimmer switch, keeping the light further away to start, or keeping it on for shorter intervals of time. All these techniques can help plants acclimate to increased light levels.

Fluorescent: Fluorescent tubes have been the standard for indoor plant lighting for several decades. They are versatile and have become more energy efficient with the invention of new bulbs and improved ballast designs. These lights are great for giving your seedlings a head start or growing microgreens year-round. Fluorescent light does not have the ability to penetrate a lush plant canopy like some of the higher-powered light sources, but it does provide an excellent source of gentle light for young plants. Fluorescent lights give off a relatively low amount of heat and have become more energy efficient as bulb technology has progressed. One of the more exciting inventions in the world of fluorescent lighting has been the CFL (Compact Fluorescent Light) bulb. These bulbs act similarly to the traditional tube style with one major difference; they can be screwed into the standard light bulb outlet used on most lamps and light fixtures. This means that a desk lamp could be turned into a small grow light with the use of a CFL bulb. Most of the standard size bulbs are of a lower wattage and would require multiple fixtures to provide the same amount of light as one fluorescent tube. Standard fluorescent bulbs and CFL’s both come in a variety of light spectrums, which are sometimes referred to as color temperature. It is important that you purchase bulbs that give off the proper spectrum for plant growth. This is key in purchasing any grow light.  Some growers will mix fluorescent bulbs of different spectrums to achieve the correct light spectrum. Bulbs that mimic the full spectrum of sunlight are available but tend to be more costly than mixing regular bulbs of varied spectrums.

Incandescent: The classic incandescent lightbulb is not commonly used as a grow light due to several reasons. One of the primary reasons is that they give off too much heat while producing a limited amount of PAR (photosynthetically active radiation) light waves. To get noticeable plant growth from this type of bulb, you would have to place it so close to the plants that they would be at risk of injury from the heat. These bulbs also tend to be rich in red spectrum light but poor in blue, which is what makes them not ideally suited for photosynthesis. In recent years, incandescent bulbs have become less common as they have been replaced by CFL bulbs. As described above, CFL bulbs make for much better grow lights and are much more energy efficient than their incandescent counterparts.

LED: Newer to the houseplant lighting scene are LED lights. LED stands for light emitting diode. The number of diodes in an LED fixture can vary greatly depending on the size and wattage of the light. Some research is required when selecting an LED light that is both functional and safe. A quick search will reveal that there are many companies producing this style of light but not all bulbs are well built or designed; this can cause a lot of variation in the output of the light. Reputable sellers will provide a chart showing the amount of light that will reach plants at varying distances. The light amount is measured in a unit called PPFD (photosynthetic photon flux density). This is usually a better indicator than wattage and will provide a more accurate idea of how powerful the light is before it is purchased. Like other lights, LEDs come in a variety of spectrums; with warmer temperature lights to promote flowering and cooler temperature lights to promote vegetative growth. A blend of the two, resulting in a bluish/purple light spectrum is a popular and effective option.

HPS (High Pressure Sodium) and HID (High-intensity Discharge): These grow lights use gas filled bulbs that create a powerful amount of light. They have been the standard grow light in production greenhouses for many years; only recently have LEDs begun to takeover. While these lights are extremely effective at encouraging plant growth, there are a few factors that make them less practical for your home lighting needs. One factor is that these lights produce a lot of heat. This can be hard to manage in a home and may even become dangerous if not properly vented. Another is cost, both for operating the light as they are not very energy efficient and for replacement bulbs and hoods. The bulbs have a shorter lifespan than LEDs and the hoods wear out over time making the light less efficient. Cost aside, this is the most high-powered option when it comes to grow lights. The light that these bulbs put out is able to penetrate the canopy to a higher degree than other lighting options. In a production setting, where plants are being produced for profit, this light is still considered a practical choice.

How long to light: A helpful item to purchase alongside a grow light is an on/off timer. Trying to remember to turn your grow light on and off each day can become tedious and impractical. It can also result in an irregular day length for your plants; this can cause irregular growth patterns. Changes in day length, as well as temperature in some cases, triggers physiological responses in some plants. This is known as photoperiodism. Notable changes in plants that respond to variations in day length include fruit production in citrus, or color change in poinsettias. Keep this in mind when setting the light timer. Learn about the lifecycle of the plant being grown and how changes in day length will affect it when deciding how long to light its grow space. In general, it is recommended that one supplement any natural light with artificial light to create a 12-hour day for most plants. This will keep them actively growing throughout the short-day winter season.

There is nothing better than sitting by the fire on a cold winter’s night with a brand new seed catalogue that just came in the mail. Even better, a good half dozen or more! It seems this year is going to see even more people planting than the previous. Last year, due to COVID, more people were home than ever before. Pair that with unfounded worries over food security and it was a great time to be in the seed business. Many online retailers simply were “out of stock” with just about everything. I thought this year would be a little different with the rollout of the vaccine;  apparently people like their newfound hobby. Although stock seems to be better this year, I am still seeing “out of stock” on some favorites. I guess people will be planting again. The good part is that the retailers seem to be ready for this, not getting caught off guard like last year. I hope this trend continues, as one of the most environmentally friendly things we can do is grow our own food and support local farmers for the rest. Don’t forget, when we buy seed we are helping to support agriculture as well. Take a look at where the seeds come from – you might be surprised how many companies are located near you.

So the question becomes, why would someone want to start their own flowers and vegetables from seed? The reasons are many. For some, it is a hobby, and a way to get into gardening before the outside is ready to cooperate. For others, it is a bit of security and a stress reducer, as they know they will have the plants they want this spring. It sometimes can be a cost savings, although by the time you buy the seed, the potting equipment, lights, other supplies, and electricity, you probably will not save much. Of course, if you continue this tradition year after year, it probably does save money in the long run. For me, it is a nice way to get the varieties that I want when they are not commercially available, and that is priceless!

The first thing to know about seed starting is that timing is everything. If you start too early, your plants get tall, fall over, and may run out of key nutrients. When you go to plant them, they are already so stressed and nutrient deprived and may not fare well. On the flip side, if you plant too late, your plants will be tiny with a poorly developed root system. As a result, they may not be able to withstand the stress of transplanting. Check your last frost date and read the information on the seed packets or seed catalogue and mark your calendar. You also will need to adjust from year to year depending on your lighting type and intensity. Each crop will have its own timing, so what works for one may not work for all. In addition, not all plants can tolerate transplanting.  Beans, squash, and cucumbers, for example, are best sown directly in the garden. Tomatoes, peppers, and eggplant are less sensitive and can handle the transplanting process much better. If you must start delicate plants indoors, I would recommend using peat pots which can be placed directly into your garden, and will break down during the growing season. I usually rip some holes in the pots before planting, being careful not to disturb or break up the roots.  

In order to germinate, seeds need the proper moisture and temperature. It is a little like the story of Goldilocks and the porridge. Although the parameters are not as narrow, they do need to be in the right range. Germination can be sped up with a heat mat underneath. These heat mats, however, are pricey and need to be used with a controller to set the proper temperature. Even without a heat mat, seeds will germinate fine at room temperature (it will just take longer).  Don’t forget to take into account the time it will take for the seeds to germinate when you are estimating how far ahead to start your seeds. One other consideration is the size of the container you will germinate the seeds in. Although you can use pots, you might run out of space rather quickly. Many people prefer to use plug trays. There are different sizes for different sized seeds and growth requirements of the specific crop. Standard sizes include 128, 72, 50, etc. These refer to the number of plants you can fit into the tray. For really large seeds or large plants, you will need to switch from plug trays to actual pots. Plants must be sized to the appropriate sized plug or pot. Too big and the soil will fall apart when transplanting, too small and the plant will have stunted root growth and/or dry out too quick. Use any commercially available seed starting medium to fill your plug trays or pots. In addition, seeds may just be sprinkled into an open tray for sprouting and transplanted on from there.

The plug trays will need to be kept in some kind of basin that holds water if you are starting them in the house. Be careful when purchasing/ordering these bottom trays so they do not have holes in them. Greenhouse growers prefer the holes so the water can drain freely. In the home, that could ruin the table or counter the trays are sitting on. You must be careful not to overwater.  Soggy seed starting medium leads to a plethora of diseases. One of the most common ones is “damping off” where your plants seem to rot right where the stem goes into the soil. Good air circulation and watering only when necessary can prevent a lot of trouble. Generally, the seed starting medium only needs to be kept moist during the germination process. Once the plants are up and growing, allow some drying between waterings to prevent many diseases.

After the seeds sprout, you need to give them light. The ambient room light will certainly not be enough, nor will placing the plants near a window (in most cases). Fortunately, it is easy and relatively cheap to provide lights for the plants. A simple old-school four-foot shop light is all that one needs. You’ll want to hang the lights a few inches above the growing plants. For bulbs, you can use one “cool white” and one “warm white” light bulb. If you are willing to spend some more money, you could buy a specialty plant grow bulb and a daylight deluxe light bulb. All of these bulbs have different spectral outputs (different colors of light) and are beyond the scope of this blog topic. Simply put, plants need lots of red and blue light to grow well. You can even find special LED plant lights with blue and red LEDs. These fixtures are much more expensive, but the bulbs are long lasting and do not lose output like the fluorescent ones. Either way, as your plants grow, you can raise the lights above them to accommodate their height. If you have different types of plants, some may grow faster than others. Do your best and develop a method that works for you. Follow the advice given here and enjoy the process! This should be an exciting and fun adventure. In a few months it will be time to put in the cool weather crops, so if you haven’t purchased your seeds yet, now is the time. Many local garden centers as well as big box stores carry a large selection of seeds. There are many mail order companies out there as well. The best part is, once you order from them, they will send you a catalogue the next year.  Not all companies are the same, and some specialize in certain types of plants. A word of warning – it is easy to imagine yourself planting away in the spring garden from your favorite chair during the winter. Buy what you can reasonably plant in a season, otherwise you may find yourself with a lot of leftover seeds. Use the information in the catalogue to figure out how many seeds you need for your space. Unused seed may germinate the next year, but they must be stored properly. Different plants have different lengths of time the seeds are viable.

Hopefully this post has inspired you to try starting some flowers and vegetables from seed. I recommend starting off small, with only one or two types or varieties of plant. Tomatoes are probably the most forgiving of our garden plants and are a great place to start.  As always, I recommend a soil test before planting out for best gardening results!
