Late winter blooms:
Galanthus, or snow drops, bloom the earliest. “If you’ve wondered whatthose little white, bell-shaped flowers are blooming in people’s yards startingin late January, they’re probably snowdrops, Species crocuses start blooming in late January or early February, followedby large-flowered Dutch crocuses in February and March.
Also blooming at this time are winter aconite, which resemble low-growingbuttercups; chionodoxa, which have pink, white or blue star-shaped flowers; andsquill, which have deep-blue flowers.
Early spring blooms:
Anemone blanda bloom in March and April and have purple, pink or whiteflowers that look like asters. Also blooming at this time are grape hyacinths,with grape-like clusters of purple or white flowers, and iris reticulata, whichlooks like other irises but grows only five inches tall.
“Some more familiar flowers also bloom during these months, such ashyacinths; double-early, Kaufmanniana and Fosteriana tulips; and miniature andtrumpet daffodils,.
Flowering bulbs can be planted in formal or informal beds, rock gardens andin established ground covers. Most prefer partial shade, so avoid planting themwhere they will receive direct midday sun. Heated basement walls can damagebulbs, so plant them at least five feet away from foundations.
“Keep in mind that you can fit a lot of bulbs in one space by plantinglarge bulbs, covering them with two inches of soil and planting small bulbs ontop of them,” says Nuss. “You also can plant shallow-rooted annuals ontop of bulbs.”
Bulbs need good drainage and a high amount of organic matter, so if your soilis mostly sand or clay, mix in peat moss or compost until organic matter isabout 25 percent of volume.
When planting tulips, daffodils and other large bulbs, dig out the entire bedto a depth of about 8 inches. Arrange the bulbs six inches apart with thepointed ends up. Smaller bulbs such as crocuses and grape hyacinths can beplanted three inches apart and five inches deep.
Before covering the bulbs, add one rounded tablespoon per square foot ofeither a sulfur-coated, slow-release fertilizer, or one handful per square footof bone meal plus one tablespoon per square foot of 8-8-8 or 10-10-10fertilizer.
You then can replace half the soil and water the area thoroughly, add theremaining soil, and water again. “A three-inch layer of wood chips, peatmoss or bark will retain moisture and keep mud from splashing on the flowersnext spring
When shoots start breaking through the soil in the spring, sprinkle a secondapplication of fertilizer around them. As flowers fade, cut them off so theydon’t go to seed and rob nourishment from the bulbs.
“The foliage gathers nutrients for the next season’s growth, so allow itto completely die before removing it,” says Nuss. “Other than thesefew steps, spring-flowering bulbs don’t need much attention. They’ll come backyear after year, just when winter seems as though it never will end.”
