Yes, French orchids should be pruned constantly in cultivation. When the old leaves turn yellow, they should be cut off in time to facilitate ventilation, and the dry tips of some leaves should also be cut off. In particular, leaves damaged by pests and diseases need to be removed in time to avoid infection. When cutting off infected leaves, don't cut off diseased leaves with scissors to prevent virus infection. If the same scissors are used, they need to be disinfected.

In order to suppress the occurrence of orchid diseases, besides properly controlling the dry humidity of potted soil, pottery pots should be used as much as possible in the selection of flowerpots, and glaze pots should be used less. Doing so makes the pot soil easy to dry, which can promote the growth of orchids and reduce the incidence.
