Defoliation

About Defoliation

Defoliation refers to the premature loss of leaves, often caused by fungal infections, insect damage, or environmental stress. This condition weakens trees and shrubs by reducing their ability to photosynthesize, making them more vulnerable to pests and harsh weather. In Middle Tennessee areas like Franklin and Brentwood, timely treatment is essential to protect landscape plants from severe defoliation during the growing season.

Defoliation is an abiotic disorder — a non-living, environmental cause of plant damage — commonly encountered in Middle Tennessee, including Columbia, Thompson's Station, Spring Hill, and the surrounding areas. This entry is part of our Abiotic Disorders Library.

Unlike diseases caused by fungi or bacteria, abiotic disorders cannot be treated with pesticides. Correct diagnosis is essential — our UT Certified horticulturist can evaluate your lawn or landscape and recommend the right corrective action.
