Best Spring Bulbs for the South Central Region
Spring Bulbs, Spring Flowers
Your moderate climate with its mildly cold winters and hot, humid summers, suits most spring-flowering bulbs except for those that have longer cold requirements and drier summer dormancy.
Optimum Planting Time: October 15th - December 15th
USDA Hardiness Zones: 7, 8
- 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.
A number of bulbs do naturalize in this climate. Many heirloom or 'pass along' bulbs are found around old homes and cemeteries. Some tropical, semi-tender bulbs winter-over here with proper micro-climate placement and a mulch blanket.
While every effort has been made to describe these plants accurately, please keep in mind that height, bloom time, and color may differ in various climates. The description of these plants has been written based on numerous outside resources.
