Q.Rose buds that fail to bloom
This is a standard rose bush. Second year in the ground. A very healthy bush full of greenery and buds. However, the second year the buds become deformed at different growth sizes and will then fail to bloom and can sometimes fall off. There is some evidence of green fly but not overly so. There is no evidence of this problem on any of the other rose trees/bushes. What could it be and how can I treat it?
