The successful application of spray to control insects and plant disease depends on several factors:

• 1.) The problem you wish to control

• 2.) The time of year

• 3.) Proper spray ingredients

• 4.) Complete spray coverage

Some problems can be controlled by one spray application while other problems may need repeated applications.

The average yard requires a 6 spray program on the ornamental trees and shrubs to aid in controlling insects and plant diseases.

Please keep in mind, our Northwest weather conditions may vary the timing of sprays as we cannot spray in the rain or during windy situations.

Most sprays generally are effective from two to four weeks, depending on the weather and the chemical used.

We offer a Tree and Shrub Deep Root Fertilizing program consisting of an early spring feeding of all ornamental trees and shrubs and a late fall feeding of Rhododendrons and Azaleas.

Native trees and shrubs do not require fertilizing and may even cause burn or root problems.  Please ask our technicians if this is a concern for you.
