Every day I look out my window and see several rose bushes with canes flattened to the ground. Sometimes the canes are detached at the base, other times they are barely hanging on to the base and just touching the cane makes it detach. (I am talking about canes that are broken underground, not further up.) Here are pictures..... There is a small hole in the rose garden which I assumed is a chipmunk. Is this damage from an animal chewing ( although they are breaking under the ground) or is it from an animal pulling down the canes and snapping them? It's distressing because this spring I had to prune most of my roses to the dirt. This new growth is very important to me. Kind of stressed about this.
