Homemade Treatment for Rust Diseases on Roses
- 1). Pour the vegetable oil, liquid soap, Listerine and baking soda into the tank of a 1 gallon garden sprayer.
- 2). Add 1 gallon of unchlorinated water to the garden sprayer tank. If unchlorinated water is unavailable, pour 1 gallon of chlorinated water in an open container and allow it to sit for 24 hours. This allows the chlorine in the water to dissipate into the atmosphere.
- 3). Pour the apple cider vinegar into the tank. The apple cider vinegar is poured in last so it does not interact with the baking soda and begin to foam or effervesce. Gently shake the garden sprayer to mix the ingredients.
- 4). Spray the homemade treatment over the entire rose bush. Concentrate on the underside of the leaves where rose rust disease is usually found.
