Russell Tree Experts offers fertilization services for trees and woody plants to help maintain tree health and vigor and to improve the condition of the soil. Without the proper nutrients, a tree’s health and growth can be stunted and appearances can start to look unsightly. Symptoms of nutrient deficiency may include yellowing chlorotic leaves, brown necrotic leaves, wilted leaves, and leaf scorch. Some nutrient deficiencies can resemble symptoms similar to pest or disease issues, which is why we often recommend a soil, leaf, or plant tissue sample to diagnose the problem and recommend the best management strategy.
