Plant your bulbs anytime before the ground begins to freeze – there’s no need to rush. In the meantime, store them somewhere dark, cool, and dry. The ideal planting time is after the first killing frost when you’re raking leaves and doing other fall cleanup chores. Soil temperatures should be at least 55ºF or cooler.
If you garden in a warm climate (zones 8-10), your bulbs may need to be pre-chilled before planting. For instructions, read How to Grow Spring Bulbs in Warm Climates.
