Fertilization of Phalaenopsis

Phalaenopsis should be fertilized frequently because of its fast growth and long growth period. The orchid plant has just changed its basin in May and is in the recovery period without fertilization. From June to September, it is the growing period of the orchid plant. It should be applied once a week so that foliar fertilizer and potassium dihydrogen phosphate can be used alternately, or farm manure can be used to add water to ferment and then irrigate fertilizer water. Under certain conditions, special orchid fertilizer and "Huabao" liquid fertilizer can be diluted 2000 times to spray on the leaf surface and cultivation substrate, and stop fertilizing in summer when high temperature. At the end of autumn, the growth of orchid plants slows down, and fertilization should be reduced. Too much fertilization often causes orchid plants to be too exuberant, affecting the formation of flower buds and preventing them from blooming. Extracted from the Treasure Book of Orchids
