Bloom balling
The very full, heavy flowers can flop or fail to open in rain. Provide an open, sunny site and consider light support for laden stems.
Blackspot
Possible in damp seasons despite good vigour. Maintain airflow, water at the base, clear fallen leaves and use preventative sprays when needed.
Stem flop under bloom weight
Large blooms can weigh stems down. Grow in a sheltered spot, feed for sturdy growth and stake heavily laden plants if necessary.
