Q. What is the best season to plant an Elm?
The success of your new tree or shrub begins with planting at the proper time of year and both late fall and early spring are fine, though spring is preferable. As a rule of thumb, deciduous plants should go in the ground when dormant (leafless) but when the earth is unfrozen, in late fall or early spring.
You have chosen a great tree for disease resistance and stamina. Be sure to give your tree a site with excellent drainage and full sun. For more information on planting and siting your tree, refer to our guide Selecting, Siting and Planting Trees and Shrubs.
