TREE WATERING GUIDELINES
April 5, 2019

Agtivate™ repairs the soil, supporting soil ecology and enhancing soil health and function, which means that it works on trees just as well as it does on row crops, garden vegetables, ornamentals, and grasses! We have put together some easy-to-follow guidelines on how you should water your trees. Simply dilute Agtivate™ as recommended (1 gallon to 320 gallons) and water your trees of any age or type and watch them grow!
(NOTE: We are not specialists on tree treatments and recommend that you consult an arborist for more information.) Visit: https://www.princetontreecare.com/tree-of-knowledge/caring-for-young-trees for more information
- Mix Agtivate™ at recommended dilution rate, i.e. 1 oz Agtivate to 2.5 gallons water (non-chlorinated)
- Apply 10-15 gallons of water (with Agtivate™ already diluted in it) for every inch of diameter of tree trunk measured at knee height. (This is a simple rule for all trees regardless of species and age.)3
- The amount of water to be applied will vary according to tree type, tree age, tree health, soil types and dryness of soil.
- The table below gives frequency of watering by tree type:
Tree Type | Frequency | Quantity | Drip* & Sprinkler*** Run Time |
Low water needs species | Once or twice in the dry season | 10-15 gallons/inch of trunk diameter | Drip: Approx. 90 minutes Sprinkler: Approx. 45 minutes |
Moderate water needs species | Every other month | 10-15 gallons/inch of trunk diameter | Drip: Approx. 90 minutes Sprinkler: Approx. 45 minutes |
High water needs species (Thirsty trees) | Monthly | 10-15 gallons/inch of trunk diameter | Drip: Approx. 90 minutes Sprinkler: Approx. 45 minutes |
- . The table below gives guidance for young trees (less than 5 years old)
Tree Age | Frequency | Quantity | Drip* & Sprinkler*** Run Time |
Three days after planted | Fill the watering basin 3 times, using a total of 15-20 gallons | 15-20 gallons | Hand watering best at this stage |
First three weeks after planting | Fill the watering basin once a week | 5-10 gallons | Drip & Bubbler run time: Depends on flow rate |
Two – Six months following planting | Fill the watering basin every week or every other week | 10-15 gallons | Drip & Bubbler run time: Depends on flow rate |
Remainder of first year | Water every other week in absence of soaking rain | 10-15 gallons | Drip & Bubbler run time: Depends on flow rate |
Year Two | Every two to four weeks when rain is scarce | 15-20 gallons | Drip & Bubbler run time: Depends on flow rate |
Year Three-Five | Once a month | 20-30 gallons | Drip & Bubbler run time: Depends on flow rate |
