Ash Tree Pruning Tips

Ash tree pruning is necessary in order to train your tree to grow properly. These trees will develop a strong, healthy growth only through correct pruning methods. Pruning will also allow sunlight and air to circulate among the tree's branches which aid in the reduction of certain diseases. Ash trees do well in moist, rich soil, full sun and plenty of room in which to grow. When cared for through careful and regular seasonal pruning, these trees will grow to 80 feet high and spread out to 60 feet or more.

Benefits of Pruning

Pruning Removes Pests

Carefully inspecting your ash trees will also determine if pruning if necessary. If diseased or dead branches are noted, they should be removed as soon as is convenient. Removal will prevent pests and decay-producing elements from infecting the tree through these infected branches. Inspect the underside of tree bark for an S-shaped pattern. Emerald Ash wood-boring beetles are responsible for this pattern and have killed millions of ash trees in the United States alone. This pest attacks the trees nutrients and nutrient carrying system. If defoliation is evident, this can be caused by anthracnose. Whether it is frost damage or anthracnose damage, telltale signs of brown areas on leaves or cankers on the branches should be signs of necessary pruning as soon as possible. Insect and disease conditions can weaken the tree and lead to serious problems if not addressed quickly by pruning.

Other Pruning Benefits

Make a second cut, 1 inch past the first cut on the top of the branch. Remove the stump after the branch falls cleanly away from the tree.
