Insecticidal aquatic canna has fewer pests and can keep the water clean; Salvage duckweed in time, remove weeds and pay attention to the harm of snails.
Prune and remove old leaves and dead leaves in time to maintain the overall appearance of plants. When the plant cluster density is too high, the flower stems should be drained in time, and the stems with too high density should be removed appropriately to increase permeability and promote the growth of new buds.
