Once Ferti-lome Tree & Shrub Insect Drench is applied the product mixture runs into the soil where it is processed by the roots of any shrub or tree. Once absorbed by the roots, Ferti-lome moves up your tree 
or shrub where it provides a year-long protection against insects of all kinds.
No messy sprays, only once a year application and easy directions for controlling unwanted bugs in your yard. Great product to fight off aphids, spider mites, webworms, tent caterpillars and more!
For best results, use this product as part of an overall tree and shrub health care program before problems start. However, this product can be applied anytime except when the ground is waterlogged or frozen. These conditions inhibit the movement of the product down into the root zone. Recommended to apply 1oz. per inch of distance around trunk shrubs and 3 oz. per foot of height.
