My leaves are turning brown and rust color. They are curling up and then drop off. What is the cause?
A Snowball Bush
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.
