1、 Change the maintenance environment

If watercress green is not properly maintained indoors, it will grow in vain. The cause of overgrowth is excessive watering, followed by insufficient light. It needs to receive sufficient light, and watering should be controlled appropriately

2、 Trim properly

If overgrowth occurs, its branches should be trimmed. Leave 3-4 leaves at the lower part of each branch, and cut off all the branches at the upper part. After cutting, new branches can be formed from the leaves retained at the lower part and the leaf buds. If the longer branches are still relatively high, they can be trimmed repeatedly, and they will grow low and plump
