Planting isn't just a spring activity. If you're wondering what you can plant in the fall, the answer is almost anything. 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. 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.
Fall showers are generally plentiful, but it's easy to deeply water plants if it doesn't rain at least an inch per week.
Pests and disease problems fade away in the fall. You don't need fertilizer, either. Fertilizer promotes new, tender growth that can be nipped by winter weather; stop fertilizing by late summer.
The window for fall planting ends about six weeks before your area gets hit with a hard frost, usually September or October.
