Slow-to-establish trees, which tend to have fewer, larger roots, are best suited to spring planting. These trees benefit from generous spring rains and a long growing season before cold sets in. One drawback of spring planting: trees may still be vulnerable when the hot summer weather sets in.

On the Other: Fall Planting Is Best for Some Trees

Mid-August to mid-October can be an ideal time to plant trees that have shallow fibrous root systems. The relatively moderate air temperatures combined with the season's soil temperatures and moisture levels promote root growth. Deciduous trees are often capable of growing even when soil temperatures reach 45 degrees, so they have enough time in the fall and the following spring to become well-established before summer heat hits.

Bottom Line

The best season to plant a tree depends upon the type of tree. Trees such as maple, ash, elm, crab apple, honey locust, sycamore, linden, and buckeye can establish themselves quickly and thus are good candidates for fall planting. Slow-to-establish trees, which include include birch, oak, hemlock, willow, sweet gum, and ginkgo, are best suited to spring planting.
