Crown galls are taking over my cherry trees. I cut an enormous wisteria all the way to the ground today. I am very sad about it. How do I get it out of the soil?? I prefer something that won't hurt my dogs. Please help me.
I may not have the news you are hoping for.
Crown Gall is difficult to treat and most times removing the infected tree is best coarse of action.
