Key points of orchid planting and cultivation in spring

Water, avoid "wet" in spring, "moist" is fine! My pellet aquaculture is "permeable" once every 5 days, while New Zealand peat aquaculture is basically watered about 8 days in 5murmuri! After watering, please use a fan to dry the leaf surface to prevent stagnant water on the leaf surface to breed bacteria and new bud core stagnant water! Choose to water in the evening when the temperature is not high and the sun is abundant! Prevent high temperature from burning seedlings! Fat, what kind of fertilizer do orchids need in spring? Want many orchid babies and strong implementation of fat is the key, orchids have entered the budding stage! A small amount of nitrogen fertilizer can be used in the early stage, remember that a small amount of nitrogen fertilizer can be applied twice at most, and potassium dihydrogen phosphate can be applied many times in the later stage. Nitrogen fertilizer can promote the germination of orchids, and potassium dihydrogen phosphate can promote the root after budding. Light. The "supplementary light" of orchids in spring is very important! Orchid seedlings have entered the bud and growth period, good light can enable orchid seedlings to effectively accumulate energy, moisturize Reed heads, and strengthen new buds! The sun should be properly shaded at the end of spring to prevent high temperature from burning seedlings! Temperature, my orchids are generally not sunshaded in spring, unless the temperature in late spring is too high! "Spring cover autumn freeze", it is necessary to let the baby Lan adapt to the coming high temperature in summer! Humidity, spring season humidity should not be too high! Generally speaking, it is about 70% in 50 / 50 / 50 / 50 / 50 / 50 / 50 / 50 / 50 / 50 / 50 / 50 / 50. Especially in hot weather, the humidity must not be too high to prevent rotten sprouts! Disease control, orchid diseases generally occur more in spring, pay attention to the prevention and control of anthrax, black spots, stem rot, soft rot and so on! In general, it is mainly early prevention, especially in the rainy season, fungicides and viral drugs are often used! Generally, one drug is used three times in a row, and then another drug is used after three times, so as to avoid drug resistance of bacteria and viruses.
