If, like me, you are a gardener of good intentions, you probably have a few bags of spring flowering bulbs you never got around to planting. Well it is not too late! They can be planted as long as the ground is not frozen. It may not be as comfortable or enjoyable digging the holes in December as it would have been in early October, but better late than never. Bulbs not planted will not bloom.

Daffodils, tulips, crocus, hyacinth and scilla are commonly sold at garden centers, big box stores and through catalogs. Other species are available and all will need to be planted, and then experience a cold period of six to ten weeks to signal the bulb to bloom when the soil warms again in the spring. If the bulbs are not planted until next March or April, they will not bloom that year as they did not receive their needed chilling period. So get them in the ground now before we have to shovel snow.

Larger bulbs such as daffodils and hyacinth should be planted four to six inches deep, or two to three times their height.  Smaller bulbs of crocus and scilla go two to three inches deep into the soil. Add a teaspoon of bone meal into the planting hole mixing it into the soil in the bottom of the hole. Then place the bulb in the hole, pointed side up and flat side down. The roots will grow out of the flatter side and grow down; the leaves and stem will grow from the pointed end and reach up. If you can’t tell which end should be up, lay it on its side and each will find their way where they should be.

Bulbs can be planted in pots in potting medium for forcing indoors, too. They will still need the about ten weeks of chilling period at 40 to 45 degrees F. They can be kept out doors in an unheated shed or porch, or placed in a refrigerator which does contain any fruit. Fruit gives off ethylene gas as it ripens which will retard or kill the growing flower inside the bulb. After the allotted time, bring out the pot and all to be placed in a bright window for the warmth of the house and light to signal the bulbs to grow. This provides a nice bit of spring in late winter inside the house. After they bloom, and later in the spring, these bulbs can be replanted outside.

Annual care for bulbs planted outside is to leave the foliage on the plant. The leaves are the food factory for the bulb. Leaves are where photosynthesis happens, taking energy from the sun to convert it into carbohydrates to be stored in the bulb. If the leaves are green, let them be. Only remove them after they have yellowed and turned brown. Do not braid or wrap the leaves together either. The leaf is like a solar plate and must access the sunrays, which it cannot do if wrapped up. Flower stems should be trimmed off so energy is not wasted making a seed. Bulb beds can be fertilized after all foliage has turned brown. Fertilizing before flowering can cause disease to attack the bulb.
