A snowball bush
My leaves are turning brown and rust color. They are curling up and then drop off. What is the cause?
There are several plants that are know informally as snowball bush. If you are speaking of a viburnum, here is a run-down on diseases that sometimes affect them. Your state's county extension service is always a good resource for problems cropping up in your area. Check the website or call the office to speak to a Master Gardener.
