Learning when and how to water, prune, mulch, and fertilize pine trees is an essential part of nurturing a flourishing, healthy pine tree that can provide shade and beauty for years to come. Learn more from experts about caring for and fertilizing the pine trees under your care.
In general, pine trees will grow best in partial sun to shade conditions, where soil is moist and acidic with excellent drainage. Regular pruning and maintenance, including maintaining a thick, protective layer of mulching around the base of the tree and over the root system area, will assist the tree with producing new healthy growth and reduce the threat of infestation from pests or fungal diseases.
Fertilization is an essential part of routine pine tree care. For best results, experts recommend that pine trees be offered one cup of fertilizer or equivalent for every inch of the diameter of the pine tree trunk. In general, the pine tree's root system will extend to 150 percent of the diameter of the pine tree canopy and fertilization should be disbursed throughout the root system for best results. Fertilizer can be offered in slow-release pellet as well a liquid, or granule form. After fertilizing the pine tree, water the entire area of the root system thoroughly to ensure the fertilizer reaches throughout the root system. In general, fertilizer should not be offered until after the pine tree has been established for one full year, and care must be taken not to over fertilize.
