In general, the arrow lotus does not need pruning. If pruning is needed, the branches of diseases and insect pests, weak branches and overlapping branches can be selectively pruned, so that the leaves can be spread as far as possible without overlapping, the contact between the leaves and sunlight can be maximized, and more nutrients can be created for their normal growth. There is no specific limit to the pruning time, and it can be carried out all year round, usually after flowering and germination.
