Deep Root Fertilization: Learn the Benefits

Fertilizing tree

Deep root fertilization is a process that consists of injecting fertilizer deep into the soil for it to be absorbed by a tree’s deepest-reaching roots. Deep root fertilization prolongs your tree’s life, promotes health, and provides preventative care. Read on to learn more about deep root fertilizing and the various ways it benefits your soil and trees.

What Does Deep Root Fertilization Entail?

ISA-certified arborists use an industrial tool called an air spade to drill a grid of holes deep into the root zone (the soil surrounding a tree’s roots). The air spade injects a slow-release liquid fertilizer into the holes near the root system. This fertilizer is usually comprised of a blend of micro-organisms, fertilizer, and other organic matter. This delivers nutrients to the deepest-reaching roots (usually about 8′ to 10′ deep) that would otherwise not have such access.

What are the Benefits of Deep Fertilizing a Tree’s Roots?

Normal lawn fertilization is beneficial to grass, soil, and the shallow roots of a tree, but it is more difficult to get this fertilizer down to penetrate the roots further beneath the surface. Fertilizing the deep roots gives the entire root system access to the nutrients the tree needs to thrive. Here are some of the perks of the process:

  • Stimulates root growth.
  • Aids flowering, fruit development, and healthy foliage.
  • Creates an increased resistance to disease and pest infestations.
  • Improves soil conditions and neutralizes nutrient deficiencies.
  • Prevents chlorosis (insufficient amounts of chlorophyll that results in yellow leaves).
  • Aerates soil and reduces compaction.
  • Promotes new shoot growth.
  • Reduces weather-related injuries like frost and sunburn.
