Spring may be special, but fall is fine for planting. Turfgrass, spring-blooming bulbs, cool-season vegetables, perennials, trees, and shrubs can all be effectively planted in the fall.
Fall has distinct planting benefits. Autumn's cooler air temperatures are easier on both plants and gardeners. The soil is still warm, allowing roots to grow until the ground freezes. On the flip side, in spring, plants don't grow until the soil warms up. Fall has more good days for planting than spring does when rain and other unpredictable weather can make working the soil impossible. And there's a lot more free time for gardening in autumn than in always-frantic spring. Plus, the late season is usually bargain time at garden centers that are trying to sell the last of their inventory before winter.
