With this Spring forecast to be a wet one, it’s a good idea to spray your fruit trees and roses with a combination of copper and dormant oil. These products are often listed organic and they help eliminate pests and fungal diseases. If you have a number of trees to be sprayed you might consider calling a pest service, such as the Hitmen or Hydrex. They offer competitive prices and have truck mounted power sprayers. Ideally, one should spray 3 times a year: in the late fall, mid winter, and just before bud break. However, if you spray once or twice in the next couple of months, it will still have a beneficial effect. Copper is effective against diseases like curly leaf, powdery mildew and rust. Dormant oil smothers the eggs and larvae of unwanted insects that burrow into fruit and rose buds.
