Frequently Asked Questions About Horticultural Oil Treatments for Trees and Shrubs

With more than 40 years of experience in dormant oil treatments, Lawn Pride is the local Tree & Shrub care team you can trust. Below, we’ve compiled a few of the most common questions homeowners have about tree and shrub Dormant Oil Treatments.

What pests does dormant oil control?

Dormant oil can control a range of pests, including aphids, spider mites, mealybugs, thrips, whiteflies, adelgids, scale insects, and caterpillar eggs. It suffocates young insects and eggs, which helps reduce pest populations in the upcoming growing season.

When should dormant oil be applied?

The best time to apply dormant oil is in late fall after leaf drop or in early spring before plants break dormancy. This timing ensures the oil can target overwintering pests without harming plant growth or pollinators.

Is horticultural oil safe for pollinators?

Yes, dormant oil is safe for pollinators because it leaves no toxic residue and dissipates fast. Since it is applied during the dormant season when pollinators are less active, there is minimal risk of harm.

How does dormant oil help prevent plant diseases?

Dormant oil can help reduce the presence of powdery mildew, a common disease affecting trees and shrubs, by creating a protective barrier. By controlling insects that may contribute to disease spread, the oil indirectly supports plant health.

Can dormant oil be used year-round?

Traditional dormant oils should only be applied during a plant’s dormant phase. However, newer formulations—often called horticultural, superior, or all-season oils—can sometimes be used at lower concentrations outside of dormancy. Contact us for the best option based on your plants and season.

Is dormant oil safe for humans and pets?

Horticultural oil spray is regarded as safe for both humans and pets. It is a non-toxic treatment that doesn't leave harmful residues, making it a popular option for environmentally conscious homeowners.
