What's the difference between a white orchid and an orchid?

Third, no pruning and shaping: during the growth period, dense branches, diseased branches and weak branches should be cut off in time to improve the permeability between branches. if they are not pruned for a long time, the leaves of the plant will turn yellow.

Solution: timely cut off all diseased branches, dense branches and miscellaneous branches according to the growth of the plant.

Fourth, the occurrence of diseases and insect pests: during the growth period, there will be brown spot, aphids and other diseases and insect pests that make the leaves yellow, so it is necessary to take good prevention and control measures.
