Has anyone ever heard of Witch's Broom Disease? My rose bushes have this, and I don't know how to get rid of it or how to prevent it. Any help would be great. Thanks.
Please tell your friend that what I have discovered is that there is no cure for it. To get rid of it, prune it away thusly:
Wait for a day when it is dry and no chance of rain for 24 or more hours. Prune about 6" inches below the mass. Immediately dip the shears into a 10% bleach mixture to clean the shears. Or, alcohol may be used in a 10% solution. This will help keep the disease from spreading.
What I did was type witches broom into my search engine and read until I was satisfied. If this is the disease her plants have, she may be able to decide if it is with the photo's shown. Hope this helps.
