Dormant Oil Treatment

Unwelcomed insects can cause considerable damage to your landscape. Trees and shrubs are the costliest and the most prominent of all your plants. Oftentimes, you will not know there is an insect problem until you catch them in the act of destroying your plants during the growing season. Unfortunately, by this time they may have already done considerable and irreversible damage.

Dormant oil treatment is one way to combat insects before they break into full-on feeding mode. Insects like to spend the winter inside your trees where they can lay low, and lay eggs, sheltered from the elements. In the spring, they will emerge hungry and in greater numbers.

Dormant oils are specialized oils that are made to coat the bark of trees and shrubs before insects have emerged. This oil cuts off insects’ necessary oxygen – killing adult insects as well as their eggs and larvae. Harmful insects are destroyed before you even see them!

In late winter, your yard may look dormant but the yard work should not be. Late winter and early spring, when the temperatures are barely above freezing, is the best time to apply preventative dormant oil. Dormant oil sprays are used on trees before the buds begin to swell. Dormant oil is an oil-based product, typically petroleum but can also be vegetable oil-based, specially designed for use on fruit trees. This oil has surfactants added to enable it to be mixed with water.

You have a lot of time and energy invested in your trees and shrubs – stopping insects before they become a problem will maintain their longevity! The professionals at Nurney Landscape & Design want to help you protect your investment. Call to learn more about our tree pruning and insect management oil services, 215-794-8599.
