Fall-Planted Bulbs
Autumn planting runs on falling soil temperature, and it gives bulbs the rooting weeks they need before the ground freezes. The bulbs that go in now are the ones that flower in spring, and a mild winter is the one thing that can still change the plan.
What you'll find here
The bulbs in this group are planted in autumn and flower the following spring.
Soil temperature is the trigger, and the calendar is only a backup.
Both edges of the window cost you: too early invites rot, too late leaves no time to root.

When to Plant Tulip Bulbs
Plant tulip bulbs in fall once soil drops below 60°F and nights settle into the 40s, which usually lands 6 to 8 weeks before the ground freezes.
