Our customers love our wide variety of Leonard-brand tree fertilizer. These controlled slow-release tablets offer trees and shrubs much-need nutrients at rates of 3-4 months, 12 months, and 24 months. They are the perfect option for professional landscapers and gardeners looking for effective tree fertilization at a great value.

Tree fertilizer and plant food comes in all shapes and varieties, and at A.M. Leonard we stock a diverse selection of fertilizers from the industry's top brands. Our popular PHC Tree Saver features survival packs of mycorrhizal fungi that are a vital part of successful plant growth but are often lacking in more urban environments. For more precise nutrient delivery, check out our inventory of micro-injectable fertilizers, insecticides, and fungicides. These solutions are shot directly into the tree's vascular system, ideal for high-population urban areas where spraying is not recommended.

Healthy trees are a crucial part of landscapes and ecosystems. Ensure that your trees are fed only the best-quality tree fertilizer with help from A.M. Leonard.
