You notice abnormal flower development on cranberry cotoneaster. This stubby blossom disorder shows up occasionally but lacks clear management strategies in current research. When present, it causes cosmetic flower defects. If plants are otherwise healthy, the issue generally remains minor and doesn't require intervention beyond general plant care.
Good sanitation is your most effective tool against false blossom. Remove and dispose of infected plant material, clean up fallen debris, and sterilize your pruning tools between plants. Reduce leaf wetness by watering at soil level and spacing plants for adequate air movement. These practices reduce the pathogen load in your garden over successive seasons.
