Fungacide On My Knockout Roses They Look Sick What Can I Do

Question

What is the best fungicide to use on knock out roses Thank you Jerry

Answer 1

Not sure how your rosebushes look. Droopy leaves? You might try a couple things. One, water the rosebushes with some water that has both a product called Super Thrive in it and a Root Stimulator product in it. Water them with a fresh batch of this mix the next 3 to 4 times they need watering. For a fungicide. I have used Green Cure for many years now. They went out of business but still some on-line to be purchased. Or you can buy a fungicide called Milstop on-line and get the same thing as Green Cure. They are great earth friendly fungicides that work very well. I mix it at the Cure Rate which is two tablespoons per gallon of water. Spray every 7 to 10 days if fungus issues are present. Spray every 14 to 29 days otherwise. I use the Cure Rate mix all the time as it lasts longer and performs better.
