What is the rate of Garlon 4 per gallon when using the hack and squirt method for tree of heaven?


The Garlon 4 Ultra Herbicide label does not recommend the hack and squirt method for any plants. It is best applied as a basal bark spray or as a stump treatment. If you are wishing to not cut the trees down first, you can follow the basal bark spray directions of the product label. If you wish to make hacks in the tree trunk prior to the bark spray you can do this as well. Per the label, it is best used on trunks 6 inches in diameter or less. Trunks with larger diameters should really be cut down to a stump and then applied at the recommended stump treatment rate.
