Disclaimer:

The microinjection method is a safe and effective method of applying Nutri-Grow® to trees. This technique should be used when treating trees that are too large to safely or effectively treat with foliar application or to trees that have sparse foliage due to stress. Because the microinjection system uses a pressurized chamber, the nutrient solution forced directly into the vascular system of the plant.

Nutri-Grow® Injectable may be used twice during the growing season and may be used in conjuction with Nutri-Grow® Magnum foliar spray. Each microinjection unit contains 15 mls of nutrient solution. Use one microinjection unit for each 6 inches of tree circumference. For example a tree with a 12 inch circumference requires two (2) units.
