Treating large shrubs and trees for insect damage after it is discovered can be very difficult because of the sheer size of the plants. In addition, loosing a large tree or shrub is a lot harder to replace than a small plant. Therefore, any shrub or tree that is susceptible to insect damage should be treated yearly with Bayer's systemic insecticide and fertilizer.
Bayer's Advanced Systemic Insecticide and Fertilizer come in either a granular or liquid concentrate. Application is simple. First measure the shrub or tree according to Bayers specifications. Next apply the proper amount of systemic insecticide and fertilizer. That's all there is to it. Depending on the size of the plant, it can take up to a month for the insecticide and fertilizer to reach all parts of the tree or shrub.
