Many Petri’s lawn customers want their trees and shrubs taken care of as well. Many common plants such as Ixoras and Hibiscuis are very susceptible to piercing-sucking insects like aphids, mealy bugs, scale, spider mites, and whiteflies. Chewing insects like beetles and caterpillars can also cause damage to the foliage of trees and shrubs. Petri’s recommends that trees and shrubs get sprayed three to four times a year at a minimum and up to six times a year for best control. Many plants are susceptible to fungus as well, especially if they are overwatered. Petri’s will treat with a fungicide if a fungus condition exists.
We will also fertilize trees and shrubs at least twice a year and up to four times a year for best results. If a customer should notice a problenm with their trees or shrubs inbetween our regularly scheduled visits, we will return for free retreatment.
