90% of absorbing roots are in the top two feet of soil, with the majority of them in the top six inches. They start well out from the trunk and extend well beyond the drip line in established trees in unencumbered soil. This is the area to be fertilized with DOGGETT TREE FERTILIZER.

Injections should be six to eight inches deep using a soil probe at 100 to 200 psi. Injections should be spaced 2-1/2 feet apart on a grid into the root area. Following the grid method, you should inject approximately 1/2 gallon of fertilizer solution at each point.This will apply 150 gallons over 2,000 square feet.
