Is it Better to Plant Bulbs Earlier or Later in Fall?

Spring blooming bulbs must be planted in fall.

Spring-blooming bulbs like hyacinth and daffodils need to be planted in fall. But fall covers several weeks, and it's best to know what part of the fall is optimal planting time for bulbs.

The Benefits of Fall Planting

Planting bulbs in the fall allows them to rest in a cold environment. This rest period is called vernalization, according to the University of Illinois Extension.

Early or Late Fall?

Planting early in fall is considered better than planting bulbs late in the fall. This gives the flower bulbs a chance to establish healthy root systems.

How Early is Too Early?

Wait for an average soil temperature of 55 degrees, and an average air temperature of 50 degrees, for two weeks. Before that, store bulbs in a cool, dark place.

Can Bulbs Be Planted Late?

Bulbs can still be planted if the ground isn't completely frozen; however, they may not perform as well in the spring. Alternately, plant them in a large pot and keep the pot in a protected, cold area, such as a porch, during the winter. In spring, you'll have cheerful potted flowers to display.

What If You Forget to Plant Some Bulbs

If you forget to plant bulbs and discover them the next summer or fall, you can still plant them if they feel firm. If they are mushy, or dry and papery, throw them away.
