“My wish is to stay always like this, living quietly in a corner of nature.” Claude Monet

Any wise gardener knows that it is a good thing to walk around your own property as often as possible often to keep alert to pests, pruning needs, vegetables that can be harvested, plants in trouble or simply to enjoy the rewards of one’s labor. I am a firm believer that gardening is not for sissies nor is it uninteresting. The excitement never ends. A trip around my property this week gave a little insight as to how much activity is going on in such a small area.

Swamp milkweed flowers are great for insects, among them the Mydas fly, Mydas clavats, a large wasp mimic which was on mine. This fly is recognizable by its metallic blue color and broad orange band on the abdomen. They have clubbed antennal tips, much like butterflies, and a stout sponging mouthpart which it uses to obtain nectar from flowers.

I was surprised to find a male Melissodes subillata, a rather unknown genus of the long-horned bees, tribe Eucerini, in my front garden. Males have very long antennae, and the subillata ‘s are reddish brown. Males are distinguished by these antennae, a yellow dot on each side of the mandibles and thorax hairs that are both light and dark. Females pollinate Asteraceae family flowers including wild chicory, plus milkweed and thistles. There was also a golden fronted bumblebee in the same garden.

 Acropteroxys gracilis, the slender lizard beetle, is a member of the Erotylidae family of beetles that includes the pleasing fungus beetles. It is reported to feed on ragweed and other agricultural weeds

There seem to be few butterflies around so far, but recently there was a great spangled fritillary on an invasive spotted knapweed flower nearby. A few skipper species have been around as well as a monarch and tiger swallowtails.

Hippodamia variegate, small ladybeetles that are found especially where asters and Queen Anne’s lace occur in the wild have been studied for use as agricultural pest predators of certain aphids. The reproductive performance of these diminutive beetles is increased with the availability of Brassica and Sonchus (Asteraceae) flowers for pollen and nectar sources. Males and females have different markings on the thorax.

Because of continued hot days and drought conditions, it is important to keep birdbaths full of fresh water. Dark colored birdbaths should be kept out of afternoon sun, as should metal ones as water will get hot. A red-shouldered hawk was enjoying a very long bath in my neighbor’s cement birdbath last evening.

Trimming certain hedges now may get exciting if there are paper wasp nests hidden among the branches. Tap bushes with a long handled rake before trimming to see if there is any wasp activity. At least you will know what areas to skip for the time being. Sometimes a bird’s nest may be found there, and if eggs or young are in it, leave the nest there until young bird have fledged.

Deer, rabbits and woodchucks or other animals may be eating plants, but squirrels at my place, or at least one nutty one, are the only animal problem so far. The hummingbird feeder is drained daily – had to get a metal one because they chewed through the plastic one. Of course, this meant war, and the solution was to use string as a maze around the branches surrounding the feeder to deny access. So far, so good.

There are dozens of small frogs, toads and tree frogs all over the lawn and gardens. They seemed to appear within days of each other. There must be plenty of insects for them to eat and I am hoping they are partial to earwigs!

Here’s hoping that soon there will come an end to the heat and drought, a rainbow in the afternoon and cool evenings for a pleasant sleep. Also, that woodchucks will not like the taste of any of the garden plants and squirrels will lose their sweet tooth. I am indeed a dreamer…

Now that Spring is upon us and we are just about caught up in the Soil Lab, many of you and us have been working on our gardens. Regardless of what you are planting, there is a persistent issue that reduces growth and yields, pests. There are a few beds surrounding our lab that we maintain to make dropping off soil samples a little more pleasant (the Depot Campus where the Soil Lab is located is haunted by the way). This spring we had a Master Gardener, Rolland, working with us, and he really helped spruce up the beds.

While working on the beds, Dawn and Rolland has noticed that a few of their recently planted Asters, Dusty Millers, and Black Eyed Susans had all but been pretty much destroyed. The leaves and steams had all been chomped on by what we believe to be a hungry rabbit. We also constantly see chipmunks running around, and the occasional deer droppings.

Everyone has their own way of dealing with pests, some more humane than others. We decided to try out a Deer and Rabbit repellent called Liquid Fence. This is a humane spray derived from putrefied eggs; I would not recommend spraying this on any plants you were planning on eating! Hopefully this helps.

For those of you with your own pest problems, the UConn Home and Garden Center provides numerous facts sheets for dealing with an array of insects and vertebrate pests. Those can be found if you follow this link: http://www.ladybug.uconn.edu/FactSheets/index.php and click on the topic concerning to your needs. If you cannot find what you are looking for through the Home and Garden Center, the Department of Plant Science and Landscape Architecture offers the Connecticut Integrated Pest Management Program. The IPM is a sustainable approach based off different eco-system derived strategies for helping with long-term pest management. The IPM can help you construct a pest management program that caters to your specific situation. There is an array of different program areas (fruit, vegetables, turf, greenhouse, etc…) and resources including publications and webinars. More information on the Connecticut Integrated Pest Management Program can be found here: http://ipm.uconn.edu/root/introduction.php. Happy Gardening!

As most of you are probably already familiar with, the University of Connecticut is home to the UConn Soil Nutrient Analysis Laboratory. This lab is staffed by Dawn Pettinelli, the manager, and myself, the technician. We also have a few part time and student employees throughout the year that help with the receiving, spreading, and sieving of soil samples; among other things. We offer an array of tests designed to help homeowners, community gardeners, farmers, etc… maximize the efficiency of their soil to produce the greatest yields in whatever plant or crop they are growing, from silage corn to turf. We can test for soil organic matter content, textural fractionation, soluble salts, Nitrogen, and Carbon. We also provide tests for plant tissues and corn stalks. However, our most vital and popular test is the Standard Nutrient Analysis. This is a relatively comprehensive test that allows us to make limestone and fertilizer recommendations. We check the pH, add a buffering agent and then retest the pH. From there we are able to determine the soils capacity to resist the change in pH, this allows us to make an accurate and precise limestone recommendation, in lbs/1000 square feet, or lbs/acre, depending on the desired crop production. The second part of the Standard Nutrient Analysis is the actual nutrient content. Soil samples are analyzed for micro and macro nutrients; Potassium, Calcium, Phosphorus, Magnesium, Aluminum, Boron, Copper, Iron, Manganese, Zinc, and Sulfur. Samples are also screened for Lead. Using the nutrient results, we are able to make fertilizer recommendations based on what is being grown. We give results in N-P-K format, and also provide organic alternatives.

We get calls year round from customers asking if they can submit a soil sample, and the answer is always yes! You can submit a soil sample any time of the year, we receive soils from throughout the country (although we have to be careful of areas under certain quarantines). Generally, it only takes around a week from when we receive a sample for us to send out the results. As you might imagine, Spring is an extreme exception. We are so busy and backed up with thousands of soil samples right now, we are expecting a 3 week turn-around time. We understand that everyone is eager to get their hands dirty and work on their lawns and gardens, but waiting until Spring to submit soil samples isn’t the best idea.

We often recommend that customers take and submit soil samples in the Fall! Soil sampling and testing in the Fall is better for all parties involved. For starters, we offer a discount on the Standard Nutrient Analysis, if you submit 10 or more samples we only charge you $8 per sample opposed to $12. However, there are more practical reasons to submit a Fall soil sample. It’s easier! The soil is generally going to be easier to work with in the Fall than after a wet Winter during the first few weeks of Spring. This will help you obtain soil samples that are a more accurate representation of the area you are interested in. Every year around this time we get dozens of zip-lock bags that are filled with soaking wet soil, dripping everywhere. A Fall soil test also allows you more time to think about what amendments you might want to use, and is the perfect time to apply limestone and fertilizers in preparation for a busy and productive growing season. Applying limestone in the Fall ensures that it has enough time to raise your soil pH to whatever the optimum range is for what you plan on growing. My personal favorite reason for submitting a Fall soil sample is that we are less busy! You’ll be happier because your results will only take a few days, and we’ll be happier because the phone won’t be ringing off the hook with customers wondering where their results are! You can obviously submit a sample whenever your heart desires, but I advise you to consider sampling in the Fall. For those of you currently waiting on results, I appreciate your patience! Happy gardening!

A few weeks ago I took off for New York City to spend a few nights with my recently married friend and his wife. Going to the city a few years ago to visit him before he was married was much different than the weekend I just spent with the newly-weds. We spent most of the morning walking around different shops, getting brunch, then trying out a few different vegan ice creams. After walking off a few scoops of ice-cream, we ended up at Chelsea Market, an “enclosed urban food court, shopping mall, office building and television production facility”. My friend and his wife told me about this restaurant they dined at while on their honeymoon in Paris called Miznon. There were four Miznons located throughout the world in Tel Aviv, Paris, Vienna, and Melbourne. In 2018 a much awaited fifth Miznon was opened in the US, at Chelsea Market. Apparently, Miznon sells a world-famous cauliflower dish, that according to my friend’s wife I just HAD to try. Now up until recently I have had a very limited pallet, and had only just started eating cauliflower, and wasn’t a big fan. I expressed my disinterested to them about broccoli’s even less appealing, pale knockoff. However, they just wouldn’t let me leave without trying it. We went into Miznon, ordered, and took a seat and people-watched all the characters passing through the market. Our waitress dropped off what appeared to me to be a deflated basketball. The couple I was with could barely contain their excitement. Upon further inspection, I realized that this was not in-fact a basketball, but a head of cauliflower wrapped in parchment paper. My friend slowly unwrapped the cauliflower when I first caught a glimpse of the actual dish. When I had tried to prepare cauliflower myself, it always came out either completely burnt, or very watery. This dish was golden brown and smelt like no cauliflower I had ever smelled before.

Cflower

Unfortunately I couldn’t find the picture I took of the dish myself, so this will have to do. Image provided by: https://static.domain.com.au/twr/production/uploads/2017/08/22230751/Roasted-Cauliflower-1950.jpg

I took my fork and was caught off guard by how easily the cauliflower peeled off from the stem. After my first bite I was hooked. The consistency was so smooth, the flavors were so established; a far cry from the usual tasteless dishes I had tried before. Before we had even finished our first head we had ordered another, and I was frantically searching on my phone for the recipe. Luckily my friend’s wife already had it saved and sent it to me, which I can now share with you! Here is a link to the recipe: https://www.foodandwine.com/recipes/miznons-whole-roasted-cauliflower; and here’s a cool video of the chef preparing the dish:

Once we had our fill of cauliflower we left Chelsea Market and stumbled across the High Line, an old elevated freight line that was repurposed as a large, unique city park. The High Line runs over a mile and a half through NYC, and is filled with garden, artwork, and venues for community outreach programs. Now unfortunately I was visiting in early March, and the weather wasn’t favorable. It was cold and rainy, so we didn’t have much time to explore, and the gardens were barren. However, the little time we spent walking the converted tracks through the city was an awesome experience, and has me waiting for warmer weather to go back. More information about the High Line can be found on their website: https://www.thehighline.org/.

There is not a slower time in the garden than January when the ground is frozen, often under a blanket of snow, plants have died off or lay dormant, and most insects and small animals are snug underground.

img_20171228_135421650

Among the animals that may hibernate from October to April are slugs and snails, happy to find a site that doesn’t go below 0°F. Their eggs are also capable of withstanding freezing temperatures. So even though we can’t see them right now, they are out there, just waiting for the ground to warm up in the Spring when they can return to our gardens and feed on our new plants!

Slow moving slugs and snails are primordial gastropod mollusks (or molluscs) in the class Gastropoda and are invertebrates that may be found in salt or fresh water or on land. Gastropod is derived from the ancient Greek words ‘gastér’ for stomach and ‘podos’ for foot, their literal means of locomotion. Some land and freshwater snails and slugs have a simple lung from which they breathe while other freshwater snails such as this zebra nerite (Neritina zebra) breathe through gills. This video shows not only how quickly a marine snail can move around on its single foot but also its mouth as it feeds on the algae in this water garden tank.

This grove snail, Cepaea nemoralis, is a pulmonate land snail, meaning that it breathes through a simple lung which is somewhat visible through its translucent shell. A snail is born with a very soft shell and they need to consume large amounts of calcium early on in order for it to harden, starting by consuming the shell of the egg that it hatched from. This tiny newborn shell becomes the center of the coiled spiral that forms as the snail grows.

cepaea_nemoralis

Some shells form into elongated spiral shapes such as the tree snail of the Drymaeus species below on the left and the garden snail, Cornu aspersum on the right.

And then there is the ultimate example of recycling where hermit crabs will occupy marine snail shells whose occupants have died. This fellow was filmed in the Bahamas:

The shell-less gastropods, or slugs, that are common to Connecticut gardens include the netted or grey garden slug, Deroceras reticulatum. It is a major pest which loves to feed on leaves, seedlings, and young fruit such as the developing cucumber shown below. The cucumber is shiny with the slug’s slime.

These small slugs actually thrive in cultivated areas such as our gardens and landscapes, feeding at night and sheltering under stones or litter during the day. An interesting aspect of ‘slug watching’ is seeing their bodies lengthen and thin out and then contract and grow bulbous again as they move along. They almost seem to be formed a of a thickly viscous fluid as they drape over a plant or rock.

Also familiar to the Connecticut gardener is the slug Limax maximus, shown below, so called as it can grow to 5” in length. It is a nocturnal slug that returns to a particular crevice under stones or fallen trees after foraging in lawns, gardens, cellars, or damp areas. Also known as the great grey slug or the leopard slug due to the dark blotches that stand out against the lighter background of its upper body, it is a detrivore, meaning that it feeds on detritus such as dead plants and fungi although it can be a major pest in a garden where it can consume young plants. It will pursue and consume other slugs if it feels threatened.

The black slug, Arion ater, is rarely a pest in gardens, preferring terrestrial areas. This slug will contract into a spherical shape when threatened but can reach up to 4.5” when expanded to its full length.

large black slug, arion ater

Slugs and snails both produce a layer of protective mucus that is a combination of lubricant and glue from their foot which is useful in both movement and in securing the creature to surfaces. Another type of mucus coats the body to prevent desiccation, aid in healing, and protect soft body parts. Snail slime is currently an ingredient in many cosmetics where those same properties are desired, so land snails are bred on farms for the cosmetic industry. Snail farming is known as heliculture or heliciculture which derives its name from the family Helicidae to which snails belong. These farms also grow snails for consumption such as in the traditional French dish escargot or the eggs are eaten in a fashion similar to caviar.

new year new start

The start of the New Year is a good time to start new in the gardening year too. There is always something new to plant or try, or a method of gardening to embrace. The down-time of winter offers the opportunity to seek out something new.

Start a new plant. Visit the warmth of indoor greenhouses to lift our moods and possibly find a new houseplant. Succulents are readily available and easy to grow if you have a sunny window. Use a well-draining potting mix formulated especially for cactus and succulents to get them off with a good beginning. Water only when the top inch or so of soil is dry.

container-gardening_14_520914843

Another popular houseplant with many different varieties and forms is Peperomia. They come with solid green or variegated leaves, some with white and others with reddish hues. Textures of the leaves vary by species with some smooth and others crinkled.  All plants in the Pipericeae family are non-toxic making them safe for homes with pets and small children. Known for its low-maintenance requirements, they will happily grow in bright, non-direct light and moist but well-drained potting medium. They have a slower rate of growth, keeping them in bounds of the container for a long time before the need to repot in a larger size container.

Start a garden journal. By tracking the bloom times and placement of perennials and trees, you might see a new combination to try. Having the plant’s location marked on paper helps one to find it in the garden in late fall or early spring, when it is the ideal time to move. Monitor and record the sunlight amounts throughout the year to see how shade increases over time as neighboring trees grow taller. A sunny yard can change to part or full shade over a decade or two. Vegetable garden journals and keep track of that exceptional tomato grown last year, or maybe the one that didn’t produce as advertised. This information will help plan the next vegetable garden with better or continued success.

garden journal

Start a new class to add you knowledge base of horticulture. UConn Master Gardeners offer advanced, topic specific classes around the state. These Garden Master classes are offered to the general public at a slightly higher price than UConn certified master gardeners, and well worth it. Topics range from woody plant identification to botanical drawing. Visit the garden master catalog to view classes.

mgs

The Connecticut Department of Energy and Environmental Protection offer a wide range of outdoor classes and activities. Safety in outdoor sports is heavily reinforced if you interest is in boating, fishing, trapping or hunting. Their goal is education for you to keep yourself safe while starting a new outside activity. Classes on the environment and educational hikes are offered around the state at seven different educational facilities. 

trailhike

Start a new book. New publications in the non-fiction realm of plants include three winners from the America Horticultural Society. One is about bees and native plants needed to feed them, another on the subject of a cut flower farm, and the third is about trees of North America. There is many other great garden and plant books to start you own self-guided learning on subjects of interest to you. I was gifted the two below written by Carol J. Michel which look entertaining and educational.

books

Start anew by joining a group of like-minded plant people. Garden clubs offer talks and friendship with other members, and some have civic minded projects involving gardening, usually by town. The CT Horticultural Society offers monthly lectures to state wide members and others, for a fee, and occasional hands on workshops. They list their scheduled speakers on their website. Other groups are focused on one subject, such as the CT Valley Mycological Society where you can learn all about mushrooms and fungi. There is also the Hardy Plant Society, and the CT Rose Society. If your tastes are more specific, check out the Iris Society or the CT Dahlia Society.

-Carol Quish

It’s that time of the year again: the Christmas holidays are days away. If you are looking for last-minute gifts for the gardener in your life then here are some ideas, including some new trends.

Herb-growing kits are one of the latest trends in indoor gardening. I always bring an herb planter in at the end of October when it gets too cold at night for it to remain out of doors. It generally does very well in a southwest-facing den window for a few months but the reduced sunlight and cooler nighttime temperatures usually cause it to gradually decline in vigor.

IMG_20181219_133207047_HDR

Unfortunately, the window in my kitchen faces northeast and therefore is the least desirable growing spot in our house. There are many herb growing kits available now that have growing lights built into the units so that if you or your gift recipient also have a kitchen with a window that gets low light (or no window at all), fresh herbs can still be within reach of your culinary efforts.

IMG_20181218_172732064_HDR

There are more than a few lower maintenance herb kits that come in a variety of containers, one of which is sure to fit the décor of any home. Burlap or heavy paper bags come complete with all that is needed to grow flowers and herbs.

The Eggling kits would be a great gift for a young gardener who would really enjoy cracking open the top of the egg to see that it contains everything (except water) that is required to grow herbs, strawberries, or flowers. Colored glass canning jars contain everything from herbs to palm trees!

Another way to grow fresh herbs or micro-greens is a portable water garden that incorporates a fish tank and a plant bed in a unique symbiotic relationship. We gave one of these to our daughter for her birthday in April and have seen the mini-aquaponic system in action. The cut-and-come-again micro-greens that sprout and grow to harvesting size in a week to ten days include radishes, broccoli, arugula, spinach, and wheat grass.

This closed system circulates the water from the fish tank up through the rock garden that sits atop the tank. As this water is rich in fish waste it supplies fertilizer to the plant’s roots. The water that is returned to the fish tank has been cleaned by the plants.

Once the herbs have been grown, whether indoor or out, there are special containers to keep them fresh and assorted culinary tools to prepare them such as a stripper that eases the removal of small leaves from herbs such as rosemary and thyme. A larger variation of the stripper works well with larger-leafed vegetables like kale. A cactus-shaped herb infuser allows any cook to add a bouquet garni to their cooking pot and then easily remove it before serving.

If your gift designee would prefer to adorn their table with flowers rather than grow them then there are plates for every style, from bold orange, green and black tropicals to powder blue backgrounds with delicate cherry blossoms to, my favorite, the high-contrast black and cream Queen Anne’s lace.

And of course, there is the traditional and always welcomed hostess gift of a flowering plant. Poinsettias are not the only way to brighten a home during the winter. Florist’s departments are teeming with an abundance of colorful blooms. Kalanchoe is a succulent houseplant that may be found with white, red, yellow, orange, and fuchsia long-lasting flowers.

IMG_20181218_185855796

Anthurium, with its dark green, heart-shaped leaves and a tall spike of minute flowers that sit above a brightly-colored bract that may be white, pink, or red is a lovely houseplant.

IMG_20181218_185908091

Flowering plants in the Cyclamen species include Cyclamen persicum and C. coum, both of which bloom in the winter and C. repandum which blooms in the spring would be welcome gifts. Cyclamen have beautifully variegated leaves and up-swept flower petals that range from white to soft pink to deep red.

IMG_20181218_185834719

But if you are looking for a flowering plant that comes in a color to match any décor than nothing can top the appeal of the dramatic Phalaenopsis orchid hybrids. As seen in the image below, they are available in a veritable rainbow of colors.

IMG_20181218_185844047

Here’s a  suggestion that may also be a final destination for plant and herb refuse: a kitchen compost bin. Now available in many materials and sizes, these bins make composting easy and may only need to be emptied on a weekly basis, perhaps a bit more often if the household is basically vegetarian like ours is or if there is a coffee-lover filling it with used grounds.

IMG_20181218_173553169

If your gardener is also a coffee lover, then these mugs that reflect the current succulent houseplant trend would receive a warm welcome.

IMG_20181218_173732745

Its not too late to shop for your favorite gardener or, if one or two of these gifts happened to catch your eye, then print this off, circle your choices and leave it where Santa may find it!

maple tree color

Fall has settled in finally, bringing its colors and cool weather. Some foliage colors were mediocre this year, always to due to the weather. It stayed hot for a long time and we did not get the cool night temperatures which help to trigger the trees to slow down and get ready for dormancy with the side effect of changing leaf color. Still there were some nice sights around the state. Japanese maple ‘Full Moon’ is a reliably consistent beauty sporting bright red leaves for a week or more before dropping its foliage.

Evergreen trees also drop foliage, but not all needles at once. The newer green needles will remain on the branches for several years. Eastern white pines will shed their oldest, inner most bundles of needles each year by first turning yellow, then brown and drop. Notice the healthy, younger green needles are retained on the growing ends of the branches.

Fall is time of seed and fruit production in the cycle of life of plants. Crabapples are a great source of food for birds and animals throughout the winter. Some trees have very persistent fruit, hanging on throughout the season, ensuring feathered and fur beings a meal. Viburnum species also are in fruit as are winterberries.

Another interesting tree producing seed pods is the Japanese pagoda tree, Styphnolobium japonicum. It also goes by its other common name Chinese scholar tree due to it commonly being planted around Buddhist temples in Japan. It is native to China and Korea. Panicles of scented white flowers are produced in late summer, turning into strings of pop bead looking yellow seed pods in fall. Pods then turn brown staying on the tree though winter. Japanese pagoda tree makes a great, small specimen tree in yards and larger gardens.

Fall is a good time to gather dried seeds from annuals and perennials you wish to grow again. Many reseeding annuals drop their seed and seem to pop up as weeds. Collect the seed in paper envelopes or containers to grow them where you want them next year. Cleome, Verbena bonariensis, dill and fennel are just a few that consistently popup all over my gardens. The annual yellow and orange gloriosa daisy evens spread to my adjacent neighbors from the birds eating the seed heads I leave up for them. Some hybrid seeds will not come back the same if you save and plant the seed the following year. Every year I plant blue or blue striped forms of morning glory to climb up the gazebo. They set tons of seeds and drop to the ground to sprout and grow the next year. Unfortunately, they come back a deep purple, not the blue. If I don’t rouge out the volunteers from the new blue flowered plants I put in each year, I will have a mixed show of the blue I newly planted and purple that reseeded themselves. I consider the purple weeds, but others might disagree.

Speaking of weeds, I noticed it was a banner year for Pennsylvania smartweed, Persicaria pensylvanica,   formerly called Polygonum pensyvanicum . Smartweed loves it moist and it responded well to all the rain we had this spring and summer, growing like gangbusters and producing a multitude of seed. On the positive side, songbirds love the seed and will be well fed during their time here. Too bad the prolific seed production is going to add to the seed bank in the soil for following years.

This year of moisture also lead to much fungal production. Tomatoes were more likely to succumb to early blight and Septoria leaf spot due to leaf wetness aiding disease development and spread. Fungicides applied before fungus hits can protect plants. So will proper spacing of plants and pruning branches to increase airflow and dry leaves. High humidity and lots of moisture ensures mildews, too. Lilacs will develop powdery mildew during mid-summer, but still come back strongly the next year. I just chose to not look at them after August.

Insects are always a part of the garden be it vegetable or perennial. We need the insects for pollination and cycle of all life. The pest ones were not too bad this year as I kept up the removal and scouting for eggs on the squash and squishing caterpillars and worms on the kale, cabbage and Brussels sprouts. Tomato hornworms made a brief appearance, but I caught them in time before much damage was done. Thankfully the cucumber beetles were low in numbers this year and manageable with hand picking them off. I am often fascinated with the beauty and intricacies of insects. I found the delicate dragonfly dead on my breezeway and could not help but marvel at its color and patterns on its body. Dragonflies dart about the yard zigging and zagging at breakneck speed while feeding on the tornado of gnats in the very late afternoon. I call it the dance of the dragonfly and now I see they come dressed in their finery for the occasion.

The season wasn’t all work, nor should it be. We made time to enjoy the fruits of our labor and spaces we created, and hope did also. With summer and the main growing season are behind us, I hope it left mark on your heart and memories for your mind, until next year when we can all try again, try some new plant and find a new adventure.

This year I had the opportunity to work in the UConn Soil and Nutrient Analysis Laboratory during the ‘spring rush’. During this time the Soil lab can get up to hundreds of samples a day. These samples may come in one at a time from homeowners with established lawns or garden beds who are looking to maintain their plantings or from new homeowners who have never planted or cared for a landscape before, or dozens of samples from commercial landscapers on behalf of their clients, or from commercial growers.

For over 50 years farmers, greenhouse growers, and homeowners have been served by the UConn Soil Lab. With more than 14,000 samples coming in on an annual basis, that is a lot of soil! Soil fertility is the first building block of plant health. If a plant is not growing in soil that has the proper proportion of available nutrients then it will not grow as well as it could. Poor soil health leads to stressed plants with stunted growth and stressed plants are vulnerable to insect and disease issues.

There are a minimum of 16 elements that have been deemed necessary to vigorous plant health. In order by atomic weight they are: hydrogen, boron, carbon, nitrogen, oxygen, magnesium, phosphorus, sulfur, chlorine, potassium, calcium, manganese, iron, copper, zinc, and molybdenum. Some other elements that may not be used by all plants are sodium, silicon, vanadium, and cobalt. The big 3 are, of course, nitrogen, phosphorus, and potassium. Represented by their symbols from the periodic table as N-P-K, they are the prime ingredients in most fertilizers. The seedlings below show signs of nutrient deficiency and are in need of a weak solution of a balanced fertilizer.

 

Also essential to healthy plant growth is the pH of the soil. It won’t matter how much fertilizer is applied if the soil pH is not in the correct range for the host plant. pH stands for potential of Hydrogen and is represented by a scale that runs from 0-7 for acidic solutions and from 7-14 for the alkalis. The higher the concentration of hydrogen ions, the more acidic the sample is. All soil test results will recommend the addition of either limestone to raise the pH, sulfur to lower the pH, or no action required if the pH falls into the acceptable range for the plant/crop.

All standard nutrient analysis tests begin their journey in the same way. For each area to be tested one cup of soil is sent or brought to the lab along with the soil sample questionnaire. The standard test will provide soil pH, the macro and micro nutrients, the total estimated soil lead, and basic texture and organic matter content. Many homeowners and growers request additional tests or only require specific information in the form of textural analysis, organic matter content (measured by Joe in the images below), soluble salts, a pH only test, saturated media analysis (for soil-less potting media for greenhouses), or nitrate testing (for commercial growers).

 

This spring was very cool and wet, as we all know. Many samples were sent in later than usual and a good many were very much wetter than usual. It is important then that the first step requires that soils be spread onto paper toweling and allowed to dry.

1. Spread soils on drying rack

Once the soil has adequately dried out it must be sieved so that any rocks or bits of organic matter are removed. This step may also involve some pounding to break up any chunks of soil as shown by Skyley.

 

From there a small amount of each sample is placed in a paper cup by Louise to be tested for its pH. It is mixed into a slurry with a small amount of distilled water, the calibrated testing meter probe is placed in the mixture and the pH level is stored in the computer program for later retrieval.

 

In a manner similar to a coffee pour over, some of the soil is placed in filter paper that is resting in a test tube in preparation for the nutrient analysis. A Modified Morgan solution is the liquid used for this extraction method.

 

The nutrient analysis is done by a machine called the ICP which stands for Inductively Coupled Plasma. This machine would be right at home in Abby’s lab on NCIS! When I was in school back in the 70’s we were taught that matter existed in three states: solid, liquid, and gas. But matter has a fourth state and it is plasma. It doesn’t exist on Earth under normal conditions but we do witness it every time we see a lightning strike.  Plasma can be generated by using energy to ionize argon gas.

The plasma flame is hot. Really hot.  6000 Kelvin.  For some perspective, the surface of the sun is approximately 5,800 K.  The solution from the individual tube samples is passed through a nebulizer where it is changed to a mist that is introduced directly to the plasma flame. A spectrometer is then able to detect the elements that are present in the soil sample.

 

Additionally, the testing for phosphorus is done with this machine shown below, the Discreet Analyzer.

 

Some soil samples come from outside of CT and those may present a particular set of problems. The USDA has quarantines in several states to limit the spread of certain invasive insect pest species such as the imported fire ant, golden nematodes, and even a few plant species. For more information visit the Federal Domestic Soil Quarantines site.

Working at the UConn Soil Lab has been a great experience and quite an eye-opener. Who knew that there was so much behind a soil test?

When I first moved in to my present residence, there were neglected flower gardens and poorly maintained landscapes that did not seem to attract nor support many insects or even birds. The expression “out goes the old and in comes the new” is an appropriate aphorism for what needed to be done. The not so modest enterprise my sister and I undertook was to establish a more useful environment for pollinators, butterflies and birds. The emphasis would be mostly on pollinators, as the birds already there seemed happy enough. As butterflies often share the same flowers with bees we assumed we would attract them as well.

Out with the old…

We were able to rip out most of the plants, whether shrubs or perennials, that were really not important food sources for most pollinators, and we concentrated the first year on putting a majority of native plants like elderberry, currant, Joe-pye weed, boneset, blue curls, bloodroot, May-apple, trillium, blueberry, winterberry, Asclepias, Aronia (chokeberry), mountain mint, goldenrod and turtlehead. We also included non-native perennials that bees love like blue giant hyssop, Caryopteris (bluebeard) obedient plant, Veronicas, and yarrow.

…in with the new

The first year we saw quite a few species of bees, especially sweat bees and all kinds of bumblebees. We also had the handsome Colletes inaequalis bees, who visited the early spring flowers like dandelions, henbit, willow and maple. They actually built their solitary ground nests in the neighbor’s sandy soils, but stopped by our nearby flowers. We also had honeybees, from who-knows where. Since bees active in the fall were already there, a couple of native witch hazels were also added.

The second year we put in some annuals that flower from early summer through fall. Lantana, cosmos, Euphorbia (‘Diamond Dust’ and ‘Diamond Frost’ are really good cultivars), petunias, sweet alyssum, salvias (pink and black and blue varieties that really attract lots of bee species as well as hummingbirds) and zinnias. Non-native perennials yarrow, coreopsis and Echinacea were also added. Perennials are even better the second year, and many more species of bees were seen throughout the second season.

It is often difficult to tell native bee species apart. For instance, the tiny Halictidae family sweat bees that are metallic green can be hard to sort out. A good reference book for identifying bees and learning about the flowers they like and nesting sites they need is “ The Bees in Your Backyard” by Joseph S. Wilson and Olivia Messinger Carril. There are good photographs of the bees, and also maps showing where they can be found in North America. Good anecdotes are also a feature of this book. Douglas W. Tellamy wrote “Bringing Nature Home’, a must-read for anyone concerned about supporting wildlife through thoughtful native plant selection.

excellent resource books

Here is a link to the University of Maine’s bulletin on “ Understanding Native Bees, the Great pollinators; Enhancing Their Habitat in Maine ” https://extension.umaine.edu/publications/7153e/. This is suitable information for those of us who live in Connecticut, as the same native bees are found here as well.

Many bees are important keystone species who have an essential role in maintaining diversity in ecosystems. This is because they pollinate the flowers they will later bear fruits that will support other fauna in the system. And whatever is not eaten will fall to the ground, where the seed will produce more plants, allowing a landscape that is sustainable(as long as there is no human interference to its natural continuation). If you can provide nesting and food sources for bees that are nearby your property, that will help the birds and other fauna that share the same territory.

It has been four years since the renovations in my own gardens, lawn and landscapes. Perennials are now well established, native cherries have been planted to support both bees and other creatures, and a few more plants are popped in as we see what bees we have and what flowers they may also like. There are pollen and nectar sources from spring to fall, so many bee species that are active at different times of year will find what they need. This last summer, there were many species of bees that seemed to be new- at least we had never seen them. We had leaf-cutter and mason bees, all sorts of bumblebees and sweat bees, Hylaeus masked bees, and others.

If you are looking to add some plants to your own landscape, consider choosing something that will be enjoyable for you and then useful the native bees. Sort of a dual purpose, double-for-your-trouble investment. Itea virginica, ‘Henry’s garnet’, is a beautiful sweetspire shrub with cascading white flower spikes that are very attractive to all kinds of bees and butterflies. Tree hydrangeas, Hydrangea paniculata, are a great late summer pollen and nectar source for native bees, and Rose- of Sharon is another. They are beautiful to look at and serve a good purpose for our little native heroes of the natural world.
