Q.What Can I Use To Treat Witchs Broom On Roses?
I have included a picture of the abnormal growth, also I have other rose bushes quite close. How can I treat the infected bush and the surrounding bushes from being infected as well. Is there a product on the market to treat roses from the type of disease?
Unfortunately, there is nothing to treat roses with that have the Witches Broom or what is known as Rose Rosette Disease. The very best thing you can do for your other roses is to dig out the infected one and get rid of it. Get as much of its root system as you can. Then I strongly suggest getting some miticides such as Avid and perhaps Floramite. Spray all of your rosebushes with the Avid miticide, then after about a month spray them all again with the Floramite. This should kill mites that may be carrying the disease to your roses. I got smaller quantities of the miticides on Ebay for a very good price, as buying them in their larger amounts can be very costly.
