Rose Rosette

Rose rosette disease is devastating to roses and will be extremely hard to control if it becomes widespread. Now is the time you might notice it on new growth.
The disease causes very red foliage and stems, copious thorns, "witch's broom" at branch ends and eventual death of the plant. It seems to be spread by tiny mites that travel on the wind. The only cure for it is to pull out and destroy affected plants.

    I am glad that I have read this information on knockout roses. I planted a bush last year, and bought some yesterday. I will check them out when I get home this evening.
