Trees growing in the landscape face unique challenges. Often confined or living in inhospitable soils, tree roots can be found at the source of many issues. Below are some examples of tree problems involving roots.
Heavily compacted soil and improper planting cause problems with tree roots.
Poor planting and mulching techniques often shorten the lifespan of trees.
Heavy clay soil can limit root development in trees, increasing the likelihood of wind-throw.
Excessive pruning removes a tree’s food-supply, which can lead to underdeveloped roots.
