What Is Dormant Oil and What Is it Used for
Learn why applying dormant oil can help keep your trees and shrubs healthy and give you a head start on insect management in the spring. In this video you will learn the benefits of dormant oils and things to consider before choosing it as an option. We are commonly asked, “what can we do over winter to protect trees and shrubs for oncoming season?” Dormant oils are a great solution. Certain insects lay eggs in the fall season on trees and shrubs. Over winter and spring, larva will emerge. Untreated overtime the larva can cause significant damage to trees, shrubs and your landscape. Applying dormant oil helps control overwintering insect populations. Oils are less toxic for beneficial insects, like lady bugs, birds and other animals. Dormant oils are easy and cost effective. Things to consider before choosing dormant oils: 1. Timing Dormant oils should be applied during dormant season and before new growth occurs. Application should be applied in light winter/early spring. Optimal temperatures are over 40 degrees, but under 70 degrees. 2. Coordination A combination of dormant oil and other applications can create a dangerous compound. Know your application type and schedule for your entire property before applying. 3. Check the Label Look for a low viscosity oil which will spread more easily. Make sure it’s marked as dormant oil because other oils can damage trees and shrubs. Be sure to follow the application instructions on the label. This can be daunting!
