Deep Root Fertilization

CAMPBELL — Like any plant, trees require nutrients to grow and flourish. While trees typically derive nutrients from the soil, under certain circumstances they may not be able to get adequate nutrition, which can put them in a state of stress. This can occur when trees are situated near lawns or in areas of dense vegetation, where competition for water, nutrients and minerals is intensified. In cases of extreme nutrient deficiency, a good remedial measure is deep root fertilization.

Deep root fertilization utilizes hydraulic injection to deliver nutrients directly into the soil at the tree’s root level. The nutrients are conveyed in the form of a liquefied solution, which makes it easier for the roots to absorb them. In addition to supplying nutrition to the tree, the hydraulic injection’s lateral spray aerates the soil, providing much-needed oxygen to the roots.

Depending on the tree’s needs, deep root fertilization is typically applied one or two times annually. By providing both nutrition and oxygen, this supplementary measure can go a long way toward safeguarding the health of at-risk trees.
