Application Rates:

90% of the fine feeder roots are in the top two feet of soil, with most of those in the top eight inches. Start your application approximately 2 to 4 feet from the root flare and extend to beyond the drip line. The soil should be inoculated with a root probe going 4 to 6 inches deep from a power rig set at approximately 150 to 200 psi, depending upon the porosity or density of the soil. The root area of the tree should be injected in a grid or in concentric circles spacing 3 feet apart. Inject approximately ½ gallon of solution per injection site. Based on the 3 feet spacing this should put around 150 gallons. Site and soil conditions vary, so adjust your application accordingly. Shake before using.
