Spring is here?

Crocus It is always a joy to see the first signs of spring. It's still cold here in New Jersey and we have been having alternating warm and freezing days. In spite of that they have popped up anyway. These bulbs are four years old and still going strong multiplying every year. Sometimes I miss out seeing them because I have them covered with leaves to protect them through the winter. It is still too early to take off the leaves that are surrounding them, but they are in an area along side of the house that gets a lot of sunlight and is also protected from the wind. Tips - What can be done with spring-blooming bulbs which come through the ground in winter, due to a warm spell? If they are planted very shallowly, cover with a layer of soil, leaves, or whatever plant litter is available. However, some bulbs make early foliage naturally. Should tulips, crocus, daffodils, and hyacinths have mulch over them in fall? Not necessary except in extremely cold sections unless you are in an area subject to frequent alternate freezing and thawing. Damage is then from "heaving" of roots and bulbs from the soil. Under these conditions cover after the ground has frozen hard, with leaves, compost, march hay. This keeps ground uniformly cool and prevents damage to roots by heaving. Uncover gradually when growth appears. Crocus
