If so how much to use? I have hemlock trees with wooly adelgids.
Bio Advanced 12 Month Tree & Shrub Insect Control Landscape Formula is applied as a drench around the base of the tree. Per the product label, this product is applied once a year. For trees, you will need to get the DBH of the tree and apply 0.5 fl oz per inch of distance around trunk.
To get the DBH of the tree, measure distance in inches around tree trunk at chest height. A flexible tape measure is the recommended tool. Multiply the number of inches by 0.5. This is the number of ounces of this product to apply.
