I moved to this home (Lancaster PA)5 years ago. There are 3 beautiful roses bushes in the side garden. The first several years ( I was here)they had strong beautiful flowers on strong stems. Now the flowers are still beautiful, but the stems are too weak, and the flowers fall over. I know the previous owner put manure on his beds and took very good care of the plants. Do i need to keep up that level of care?
