dormant oil recipe

Very early in spring, while trees and shrubs are still dormant, is the time to add domant oil to the bark and buds of ornamental, flowering trees and shrubs, roses and fruit crops. The oil spray suffocates overwintering insects and prevents their eggs or larvae from developing. Spray before the buds break and when the temperature is above 4.5°C.


To make dormant oil, mix well:
1 cup vegetable oil
2 tbsp mild non-anti-bacterial hand/dish soap
