Proper fertilization can ensure the robust growth and flowering of Paphiopedilum papyrifera. However, Paphiopedilum glabra is very sensitive to salt, so it must not be applied more to avoid salt damage. If you can't master the fertilization technology correctly, it is better to apply less. Orchids in Taiwan Province Province have a good way to prevent salt accumulation, that is, water it again 1 ~ 2 hours after watering, and then the salt in the matrix can be separated out. Generally, except that the temperature is too high in winter and summer, water-soluble quick-acting fertilizer can be sprayed once every 15 ~ 20 days. Pay attention to the proportion of nitrogen, phosphorus and potassium in fertilizer, and use N-P-K = 20-20 or 15-65438 for non-flowering plants. Farmhouse manure can also be used for ground planting, but it can only be diluted and applied after being decomposed with water. All Paphiopedilum species are vulnerable to starscream attacks, especially those with smooth leaves. Therefore, please check the blade from time to time. Other pests rarely harm paphiopedilum. Common diseases of Paphiopedilum also include bacterial and fungal infections. Fresh and ventilated air can play a preventive role.
Pests and diseases of Paphiopedilum mostly occur in rainy and hot summer, and common diseases include stem rot, anthracnose, brown spot and so on. Spraying chlorothalonil and thiophanate 500~ 1000 times every two weeks can prevent the occurrence of these diseases, and improving ventilation conditions can prevent the occurrence of paphiopedilum. Common pests include scale insects, whiteflies, slugs, snails, etc. The control methods can be spraying or trapping related pesticides. Paphiopedilum virus disease is an incurable disease. Once found, it should be isolated or buried immediately to avoid infecting other healthy plants and eventually being completely eliminated.
