Deep Root Fertilization
Deep root fertilization is a process where a high quality nutrient
solution is injected into the root zone of trees. The materials are
injected into the root zone under pressure which helps aerate or provide
much needed oxygen to the root system. The soil injection begins just
below the surface and goes to a depth of twelve to fourteen inches. Soil
injection sites are placed two to three feet apart in a grid pattern
under the canopy area and beyond the drip line.
Normally, fertilization programs should be repeated once or twice a
year. There will be instances where severe root damage has occurred,
soil compaction exists, or other health problems are present. In these
instances, it may be recommended to increase the frequency in order to
improve conditions in and around the root zone which can improve overall
health and vigor.
Roots are opportunistic and develop where ever oxygen, nutrients, and
moisture are present. Ongoing deep root fertilization programs improve
the oxygen content, microbial activity, and nutrient levels within the
soil, leading to improved environmental conditions around and within the
root zone.
The formulation of our fertilizer is a custom mixture manufactured by
Plant Health Care, a leading manufacturer of organic solutions for
trees, shrubs and turf grass. The contents of our mixture is listed
below.
There will be times when your Arborist will recommend amendments to
the standard mixture when certain nutrient deficiencies or health
concerns are present.
