As winter fades and the first signs of spring emerge, now is the perfect time to give your roses and fruit trees the protection they need to thrive in the growing season. One of the most effective ways to safeguard them from pests and diseases is by applying dormant oil. At Galaad Yard Care Services, we understand the importance of proper plant care, and we’re here to help you use dormant oil effectively to keep your garden flourishing.

What is Dormant Oil?
Dormant oil is a horticultural oil used during the dormant season (late winter to early spring) to control overwintering pests and their eggs. Made from refined petroleum or plant-based oils, it suffocates harmful insects such as:
Aphids
Mites
Scale insects
Whiteflies
By eliminating these pests before they become active, dormant oil reduces infestations and prevents damage to your plants.
Why Use Dormant Oil on Roses and Fruit Trees?
Dormant oil offers multiple benefits, making it a valuable tool for integrated pest management in your garden:
1. Controls Overwintering Pests
Many insects lay eggs on trees and roses in the fall, waiting for spring to hatch and wreak havoc. A well-timed application of dormant oil smothers these eggs, preventing an early-season infestation.
2. Reduces the Spread of Disease
Fungal spores, such as those that cause black spot on roses or powdery mildew on fruit trees, can overwinter on bark and stems. Dormant oil helps suppress these spores, reducing the risk of disease outbreaks.
3. Eco-Friendly and Safe
Unlike synthetic pesticides, dormant oil is low in toxicity and safe for the environment. Once dry, it does not harm beneficial insects like bees and ladybugs, making it a sustainable choice for home gardeners.

How to Apply Dormant Oil
To maximize effectiveness, dormant oil should be applied correctly. Follow these guidelines for best results:
1. Timing is Key
Apply in late winter or early spring before buds start to swell.
Ensure temperatures are above 4°C (40°F) for at least 24 hours to allow proper absorption.
2. Mix and Apply Properly
Follow the manufacturer’s instructions for dilution.
Use a sprayer to coat all branches, stems, and bark thoroughly.
Apply on a dry, wind-free day to prevent the oil from washing away.
3. Avoid Common Mistakes
Do not spray when temperatures are below freezing. This can cause plant damage.
Avoid application on stressed or frost-damaged plants.
Test on a small area first if using on delicate plants like Japanese maples.
