When to Plant
Delivery & Planting Times
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.

To get the most from daffodils, follow these 3 basic rules:
- Plant them where they will get at least 6 hours of direct sunlight, even after they have finished flowering and the trees have leafed out. Daffodils need lots of sun after they bloom to produce next year’s flowers.
- Plant them in soil that drains well. Avoid areas where water stands after a rainstorm.
- After daffodils flower, wait at least 8 weeks—until the leaves turn yellow — before cutting them. Never tie or braid daffodil foliage. This year’s leaves = next year’s flowers.
If you want to naturalize daffodils (i.e., plant them so that they look as though they had sprung up on their own), we suggest that you set them out in drifts (not in blocks or lines) and that you space the bulbs farther apart than recommended on the bag label (to allow room for the clumps to increase in size). If you want to naturalize daffodils in a grassy area, you must wait to mow until their foliage has turned yellow, which means allowing the grass to grow very tall.
