Ash trees live for 100 to 250 years and reach heights up to 100 feet with a canopy spread of 60 to 70 feet. There are a variety of species of ash trees that are suitable for use in the landscape. The white ash is an attractive tree with grayish bark and purple colors in the fall. European ash was introduced to the states from Europe and Northern Asia, it is similar to the American black ash. Other varieties include the blue ash, the green ash and the Biltmore ash. For a list of ash trees and their characteristics, see the reference list.
Choose the planting site for the sapling that is a large area away from taller trees that will rob the sapling of light and space. Ash trees grow best in damp, slightly alkaline soil conditions.
Select a tree that is between 5 and 6 feet tall. Nurseries sell young trees either in pots with soil around the roots or bare root with the roots wrapped in cloth or plastic to protect them from damage.
Dig up and turn over the soil in an area three to five times larger than the diameter of the root ball. Dig out a planting hole large enough to place the root ball in the center of the loosened soil. Remove the sapling from the nursery pot or unwrap its roots.
Place the tree into the planting hole with the base of the stem level with the surrounding soil. When planting multiple trees, space the saplings 60 to 80 feet apart to leave room for the trees to develop. Fill in the soil adding water as you go to settle the earth and fill in air holes.
Pat down the soil to secure the sapling in the ground. Keep the soil damp around the new transplant for the first two weeks until the roots get established. Spread a 2-inch layer of mulch over the planting area to keep moisture close to the ground. Plant trees in the fall before the first winter frost.
