Getting Tulips to Rebloom in the South

Tulips often behave as annuals in warm climates like Georgia because they need two months of cool, bright weather after flowering to rebuild energy—conditions rarely met in Southern springs.

Improving Perennial Performance

1. Excavate a 12-inch deep bed.
2. Replace half the soil with a 1:1:1 mix of native soil, soil conditioner, and gritty sand for drainage and cooler root temperatures.
3. Plant bulbs on this mix, add a tablespoon of bone meal each, and backfill.
4. Choose a bright shade location, never full sun.

Recommended Varieties for the South

Darwin hybrids, lily-flowered, and parrot tulips are best treated as annuals. Species tulips like Tulipa clusiana 'Cynthia' and T. bakeri 'Lilac Wonder' perennialize better. Cultivars 'Queen of the Night', 'Maureen', and 'Pink Diamond' are also recommended.
