Isabella from Tampa Fl writes,
How often can apply the spray to my tree
Fertilome Tree & Shrub Insect Drench is applied as a soil drench so that it moves down through the soil, where it is absorbed by the roots of the plant or tree, not as a foliar spray. When using Fertilome Tree and Shrub you should treat mid-fall and again in the spring with a a soil drench. You may need to moisten the ground prior to the treatment, use the higher volume of water as recommended on the label and keep the soil moist for the following 14 days after the treatment to encourage the tree to trans-locate the product.
