Fertilome Tree and Shrub Systemic Insect Drench would be an excellent option for scale on your holly trees. You will use 3 fl. oz. per foot of height per gallon of water. This product can beused for the overall healthcare of trees and shrubs and can be applied any time the ground is not frozen or waterlogged. These conditions will not allow the product to move through the soil properly.
