Application of Human Medicines in Orchid Cultivation

Human anti-inflammatory, heat-clearing and analgesic medicines can be used fororchidpest and diseasecontrol. Generally speaking, liquid medicines can be sprayed at 1%, and tablets and powders at 1/2000. Before use, orchid growers should carry out an experiment on Tongcao (rice-paper plant pith) to observe and confirm there is no problem before using them, so as to avoid losses. Water in which beans, corn and peanuts have been boiled with their skins gives very good results when used to water orchids, and it can also be applied to weak seedlings. Although it contains chlorine, an occasional use does no great harm; it is best to let it stand for 12 hours to be safer. Song Mingyuan
