Tulip bulbs need eight to 15 weeks of chilling between 35 and 55 degrees Fahrenheit or they won’t grow shoots and bloom.

Can you plant tulips in the fall&winter?
Plant tulips in the fall for spring and summer flowers, using a layer of mulch to protect the ground during cold months. If a heavy late-spring frost threatens, cover the tender new shoots so they don’t freeze.
A loose, light mulch, such as straw, can be added around the tulip plants and buds, covering them by at least an inch, to protect them from extreme temperatures and hard frosts. This can be labor-intensive if you have extensive beds, as the mulch has to be removed once temperatures warm up, but it can definitely preserve your blooms!
