What is Deep Root Fertilization?
Deep root fertilization is a tree maintenance routine that involves fertilizing the tree’s roots directly, by applying an injection of liquid fertilizer into the soil to replenish depleted soil with nutrients. Deep Root Fertilizing is one of the best ways to get nutrients directly to your plant, while aerating the soil. Deep root feeding is necessarily beneficial in suburban areas, due to lack of nutrient rich soil.
Best Time for Deep Root Feeding?
If a tree is showing out of season yellowing leaves, deadwood, new shoots growing improperly, or visible decay, then deep root fertilization will be helpful whenever done, as long as the ground is not frozen.
Spring time root fertilization: If the deep root feeding is done for tree care and maintenance only, then ideally the fertilization should be done in the spring.
Fall time root fertilization: It will replenish nutrients used up over summer months. Also, if the ground is not frozen, then root feeding will promote root growth during the winter months.
