1. spring pruning: when plants are moved out of the house in spring, they can be pruned once. Re-cutting orchids in spring is mainly to cut each branch short, so that orchids have more lateral branches and make the plant shape fuller.

2. Seedling pruning: the orchids are pruned and reshaped, and a trunk with a height of 15cm ~ 20cm is reserved, so that the trunk branches are not exposed to the surface, but are pruned above the trunk with a height of 15cm. After pruning in Milan, the plant can continue to sprout lateral branches, which can make the crown of the plant flourish and densely spaced.

3. Pruning in summer and autumn: Pruning in summer and autumn is mainly to shorten the branches that are growing too vigorously, and remove the inner branches, pests and diseases, dead branches and weak branches, which is beneficial to ventilation, centralized supply of nutrients to other branches and flowering of orchids. Of course, pruning should be combined with plastic surgery to avoid affecting the plant shape.

4. Pruning after flowers wither: After flowers wither, orchids should be pitted, and the branches in the center should be shortened appropriately, so that they can sprout a large number of new branches, which is beneficial to the growth of plants in the coming year.
