Complete Tree and Shrub Protection

Your trees and shrubs represent a growing investment worth protecting. There are hundreds of insects and diseases which can attack and infest your landscape. Our trained and licensed technicians are able to identify and control these problems before severe damage or plant loss occurs. We offer seasonal and regularly scheduled treatments to help keep all of your ornamentals healthy and in top growing condition.

Plant, Shrub, and Tree Fertilization

At McCauley Ag & Pest, we provide applications with liquid fertilization two to three times annually. Treatments to plants and shrubs are applied topically with a mechanical sprayer. Larger trees and shrubs are treated by using a mechanical feeder and or a deep root feeder.

Tree Injections

We use tree injections as a very effective way of managing many tree problems such as insect, disease, fruit elimination and nutrient deficiencies. Are you noticing problems with your trees? Are they showing signs of canopy die back or leaf wilt? Your trees may have an invasive pest or disease. McCauley’s agricultural pest products safely and effectively manage and control tree problems threatening residential and commercial areas.

Invasive Insects

Many communities are threatened by invasive insects such as borers, beetles, aphids and scale. Are you seeing sticky residue on your car? Your tree could be invaded by aphids.


Many trees have fallen victim to diseases such as Dutch Elm disease, Fire Blight, and Anthracnose to name a few. These diseases can be treated using an injection of material that can provide control for up to a full year.

Fruit Reduction

Treating with a seasonal topical application, McCauley Ag & Pest can reduce unwanted ornamental fruit up to 70% on trees such as: Flowering Plum, Liquid Amber, and Olive.

Deep Root Fertilization

Healthy soil is one of the most important factors in maintaining a healthy landscape. At McCauley Ag & Pest we go beyond the standard landscape fertilization of other companies. Our balanced deep root fertilizer blend includes precise amounts of premium slow-release nitrogen, phosphorus, potassium, iron and a micro nutrient package designed to significantly enhance the health and beauty of your valuable landscape all season long.

What Is Deep Root Fertilization?

Deep root fertilization is applied by injecting blended fertilizer directly into the root zone of your trees and shrubs. Our timed release fertilizer formula continuously feeds and nourishes your landscape throughout the entire growing season to give you the healthiest and vibrant landscape possible.

According to most experts, the optimum time to fertilize is fall and spring. Fall deep root fertilization will help your landscape overcome summer stress and prepare for winter. Trees and shrubs will make use of these nutrients through the cooler months.

During the fall and winter they will develop reserves of nutrients in the root systems. These reserves help create superior root development, vivid green foliage, improve plant vigor and help reduce damage from insects and disease. A second application in the spring ensures this overall health over the entire year.

What Our Customers Are Saying

OMG! Glen and his crew are THE BEST! I had a rat issue for months, and after Glen came, it was resolved right away. Now we are working on making sure it doesn't happen again. I had a contract service with another reputable company for more than a year, and they really could not do as much as it was...
