Monterey Fruit Tree & Vegetable Systemic Soil Drench is not specifically labeled for cannabis so we cannot recommend the application for effectiveness or safety.
The mixing ratio for Fruit Tree & Vegetable Systemic Soil Drench is dependant upon the distance in feet from the trunk of the tree to the drip line, not the diameter of the tree trunk. Please refer to the product label on our site for information.
