When cultivating cypress, its leaves sometimes grow densely, and the dense leaves should be thinned and pruned in time to ensure good ventilation of the crown. If there are long branches, they should be pruned according to the situation. Just cut the branches shorter. If not properly maintained, dead leaves, diseased leaves, yellow leaves, etc. will also appear, so they should be cut off during pruning. In addition, it can also be shaped by tying during pruning.
