Another garden task that can be performed during the winter is spraying some of your trees and shrubs with dormant oils. There are many species that can benefit from this practice, but they are notably associated with the care of fruit trees and shrubs. Spraying them now will help your future crop production be optimal.


What Are Dormant Oils?

These products are created from petroleum and are designed to suffocate the insects that may have taken shelter in your plants for the winter. The oils form a layer on the pests that prevents them from breathing properly and hastening their demise. On some insects, the dormant oils will also actually start to eat away at their exoskeleton and inner body.

Some of these products will also help control fungal diseases that may be present in the plant. There are several different kinds available for purchase at your local garden center or nursery. The associates should be able to assist you in choosing the best option for you if you are not sure which one is necessary.

When Do You Use Dormant Oils?

As you may have figured out from the name, these products should be applied during winter when the trees and shrubs are dormant. Choose a time in the season when the temperatures are at least a bit above freezing to do your treatments. Follow the directions on the label and wear necessary safety gear like goggles and gloves.

Some insects can be very persistent, so watch for them in spring and summer to see if any survived. There are oils that can be applied in summer to help get rid of these stubborn pests.
