Climate matters. This page is a practical baseline. Confirm cultivar, local frost/heat conditions, mature size and regional restrictions before planting.

Growing directions
Plant bulbs pointed end up at a depth of 3 times their height, typically 6–8 in deep, in well-drained soil — standing water will cause rot. In warmer zones (7–8), pre-chill bulbs for 6–8 weeks in the refrigerator before planting to simulate the cold period they need. Most hybrid tulips perform best in year 1; replanting fresh bulbs annually is common practice in mild climates. Allow leaves to die back naturally after bloom to recharge the bulb.
