Hackberry is a wonderful tree for birds with their berries and it also is the host plant for the Snout butterfly. It’s a great tree but boy they can be a mess with the wooly aphid, which drops black sooty mold all over your plants, patio furniture, vehicles and more. Fertilome Tree and Shrub Systemic Insect Drench can be used to prevent hackberry trees from getting wooly aphids. The trick is to apply between now to mid April to stop them from reaching maturity.
