When pruning palm, mainly pruning withered branches and leaves can better promote the growth of new branches and leaves of palm. When pruning palms, you can prune some old leaves, which can promote the growth of new leaves, because the photosynthesis of old leaves is very poor. Pay attention to the overall symmetry when pruning to avoid obvious differences, which will easily lead to the skewed growth of palms. The duckweed after pruning should be watered reasonably. It is generally best to water once a day. After watering, make sure the soil is moist. Appropriate fertilization is also needed, and organic fertilizer is needed for fertilizer. Proper loosening of soil before fertilization can help the fertilizer to be better absorbed by duckweed.
