WHICH TREES NEED TO BE TREATED PROACTIVELY VS REACTIVELY
Find out which product you should use to control your insect pressure.
Use this chart to help figure out what trees need to be treated preventatively for insects and the trees they target. This is a guideline and not a rule. We recommend preventative maintenance for many tree species that are important to a landscape or any tree that has had insect pressure in the past.
Please keep in mind that trees that are actively growing and healthy tend to be less susceptible to insect pressure than slow growing or unhealthy trees. Deep Root Tree Fertilization is a great way to help a tree stay healthy and strong and therefore prevent insect infestations.
Merit is a wonderful preventative
insecticide for trees and shrubs.
