How to Spray Cherry Trees

By Kelly Shetsky ; Updated September 21, 2017

There are two types of cherry trees--sweet cherries and sour cherries. They produce blooms in early spring. Cherry trees are susceptible to attacks from several pests and diseases. The one that is most concerning, though, is the cherry fruit fly. The pest deposits egg right into the developing fruit, so by the time it is ready to harvest, it is ridden by maggots. The only way to control cherry fruit flies is to spray cherry trees with insecticides. A mature cherry tree can be 20 to 30 feet high, so spraying them requires special equipment.

Buy insecticide that is made for cherry trees. Read the label or ask an expert at the garden center how much you need for the number and size of your cherry trees.

Choose a calm, dry day to spray cherry trees. If it is windy, the insecticides will not stay on the tree.

Apply a dormant oil fruit tree spray in the spring before budding begins. This will help prevent insect infestation.

Spray cherry trees four to five times before fruit harvest and one to two times after, if there are still unpicked cherries.

Fill a hand sprayer with insecticide if you are spraying a small cherry tree. Hand sprayers are available at nurseries or garden centers. Use a ladder to reach the upper portions of the tree.

Call in a pest control company if you need to spray cherry trees that are too large to reach by ladder. Industrial sprayers are needed to get the job done.
