What is Deep Root Fertilization?

Deep Root Fertilization is the process where a nutrient solution of high quality and organic purity is injected into the root zones of a tree.


  • Provides proper nutrients for trees.
  • Encourages root growth
  • Aeration of soil
  • Reduction of soil compaction
  • Healthier and more attractive trees
  • More resistant to disease and insect infestation
  • Promotes luxurious foliage that adds beauty to your property

As the most preferred method of fertilizing trees and shrubs, deep root fertilization is the process of injecting a liquid, time released fertilizer about 8-12” deep and 2-3’ apart in a grid pattern around the tree or shrub. The fertilizer is injected below the roots of the surface vegetation to provide maximum benefit to the slightly deeper roots of the trees and shrubs.
