Fertilization of Trees

Fertilization aids in tree growth, reproduction and development. Before you fertilize, it is best to have a soil analysis test. Tests are available through the University of Georgia Cooperative Extension Service. Fertilization is not a "cure-all" for declining trees, but may be used to complement other tree maintenance activities, such as watering and mulching.

The ideal time to fertilize is late winter or early spring just as the leaves begin to expand. Fertilizer is not plant food, but a mix of essential elements necessary for plant survival. The most common nutrients found in fertilizers are nitrogen, phosphorus and potassium.
