Potted crape myrtles generally have fewer diseases and pests, but they are vulnerable to scale insects and sooty mold under insufficient light and poor ventilation conditions. Scale insects can be killed by spraying 1000 times of 40% dimethoate emulsifiable concentrate or by using 3% of the granular soil poison. If it is sooty mold, lime sulfur mixture can be used for prevention and treatment.

3. Trimming and shaping

Including the flower stalks after the flowers fade, in order to make them bloom better in the future, it may be necessary to cut them off in time.
