When to Plant Flower Bulbs
East Central
Optimum Planting Time: October 1st - November 30th
USDA Hardiness Zones: 5, 6, 7
Region "F" — East Central
Yours is an excellent area for most spring-flowering bulbs with moderately cold winters,
ample moisture, and warm to hot summers.
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: Extend the bloom season by selecting a range of bulbs that flower
throughout the early-spring, mid-spring and late-spring seasons. Remember that daffodils,
leucojum, galanthus and other members of the Amaryllidaceae family are generally
considered pest-resistant.
