Fertilizing with Arbor Rx

Ground Probe Root Fertilization

The root fertilization that we offer is Arbor Rx. This mixture is designed with all the necessary nutrients for growing ornamental woody plants and trees, both deciduous and coniferous. It helps stimulate root growth and protects against drought stress.

We apply it with a soil probe every four feet in a grid pattern around the tree. Our probe is set at 4-8 inches to keep the fertilizer around the roots that take up nutrients.

Trees to consider fertilizing include:

  • Young Trees that were transplanted more than 2 years ago. Fertilizing newly transplanted trees could increase the shock of the transplant. Once the tree is established, fertilizing could increase growth and reduce the possibility of pressures.

  • Trees that are growing in well kept landscapes or close to paved areas. Trees in forested areas receive nutrients from decomposing organic material. This organic material (foliage) is most likely removed on a consistent basis if the tree is in a manicured landscape.

  • Highly valued trees. Fertilizer can help a tree fight future stresses and pressures.
