Region "B" — Mid-Atlantic Coastal
In your area, you may be able to grow many of the tropical and other marginally hardy
plants by planting in warmer 'micro-climates' protected from exposure to winds and extreme
cold. If you're concerned about bulb foliage that emerges in the fall or winter, put a
light pine needle or straw mulch around the leaves to protect them from frost burn (but
don't worry, such leaf damage is only cosmetic and won't affect the flowers).
General Instructions:
Plant bulbs in the fall starting when nighttime temperatures stay between 40-50°F. But,
be sure to plant approximately six weeks before the ground freezes to allow sufficient time
for rooting. Bulbs will root best in cool soil and once rooted undergo natural changes that
keep them from freezing. Water your bulbs after planting to help them start the rooting
process.
After planting, apply slow release "bulb food" fertilizer on the top of the ground to
supply nutrients for the second year's bloom. (Bulbs are already fully charged with energy
for peak flowering performance in their first spring bloom season.) Do not put the fertilizer
in the hole with the bulb as this may burn the bulb's tender roots. PLEASE NOTE: Modern
bone meal generally has little value as a bulb fertilizer and often draws rodents and dogs
that dig up the bulbs looking for bones!
After the ground cools or freezes, cover your bulb beds with a lightweight mulch
(pine needles, buckwheat hulls, straw or chopped up leaves) 2 — 4 inches thick to
help keep down weeds and maintain a consistently cool soil temperature.
Special Note: If voles or other animal pests are eating your tulips, crocuses
or lilies, spraying the bulbs with a product such as Ropel may help protect them.
To ward off subterranean "bulb rustlers," try placing Vole Block or sharp granules
of a gravel-like substance around bulbs to help create a physical barrier. Regarding deer,
trials of products such as Deer Off, which must be applied at emergence and until
bloom, have had some success.
