Protecting Trees- Introduction:
Trees are important to your landscape, but simple actions can damage their health and life-time. The most common damage to trees occurs in three ways:
Damage to the roots is worst, because it affects the whole tree.
Most people do not know that the root zone of a tree is the area under the branches to the drip-line plus the area farther out about one-and-a-half to two times the distance of the drip-line (Ryan, et al., 2002).
Other experts indicate root spread may extend as far as two to three times the distance of the drip line (Appleton et al., 2000).
Roots grow all year long, and require air to survive. For example, roots do not grow deep into the soil in middle Tennessee, because air cannot penetrate much more that a foot or so deep in our clay soils.
