Ideal Fall planting times by Region
This map shows the ideal Fall planting windows for the United States. Please note the following:
- Bulbs that flower in spring must be planted in Fall.
There is no getting around this requirement.
- Bulbs should be planted when the soil has cooled to about 55 degrees F.
Bulbs need cool soil to make roots before the onset of winter.
- You have about 8 weeks to plant after the first frost.
As long as the ground is not frozen, you can still plant bulbs.
- Colorblends can meet your Fall planting schedule.
If you need your bulbs at a particular time, just let us know.
