Horticultural oils when used correctly can be an attractive alternative to traditional pesticides. But are they right for your garden? Learn how to use horticultural oils with confidence to control disease and insects in your home vegetable garden and orchard. Join veteran Master Gardener Bob Cain via Zoom for “Using Horticultural Oils” Thursday, Feb. 24, from noon to 1 p.m.
Bob will cover the basics of what a horticultural oil is and what factors to consider when purchasing oils, as well as the correct methods for spraying, and the use of safety and protective equipment. In addition, he will highlight why and when to spray, and what diseases and insects can be effectively controlled by the use of horticultural oils in both organic and non-organic gardening.
