However, in roses the most common cause of phyllody is environmental stress, such as hot weather when flower buds are forming, or water stress. If environmental factors are the cause, affected plants usually have normal and abnormal flowers simultaneously but otherwise look healthy. When the weather cools, the bush resumes producing normal flowers.
Rose growers familiar with the characteristics of individual varieties can assess if phyllody is caused by disease or environmental stress by carefully examining plants. A lack of stunting or yellowing and good overall growth indicate a virus or phytoplasma likely isnÃ¢â‚¬â„¢t the cause but instead an individual flower probably is responding to specific environmental conditionals.
No management practices are suggested other than pruning out individual blooms.
