Key points of orchid conservation after winter

With the gradual decrease of air temperature, the water supply of indoor potted orchids is very important, so we should water more, but at the same time, we should pay attention to watering and moisturizing. If the humidity is too low, it can be sprayed to ensure that the orchids have enough humidity to prevent the tip of orchids from withering. After the orchid plant grows in summer, the nutrients in the basin are exhausted, so we should pay attention to fertilization before winter. The method is to apply organic fertilizer to the root once every 10 days, and to spray nitrogen fertilizer on the leaf surface once every 10 days, and the two can be carried out alternately. At the same time of applying organic fertilizer, proper amount of phosphorus and potassium fertilizer can be mixed to promote bud. It is still a season prone to soft rot, stem rot and other diseases, and insecticides such as agricultural streptomycin, chlorothalonil and methyl topiramate can be sprayed alternately. Sunlight can enhance the ability of bluegrass to resist diseases and insect pests and cold, so bluegrass should "bask" in the sun more at this stage. For orchid varieties such as sword orchid that bloom in summer and autumn, the flower branches should be cut off and nutrients should be replenished in time after flowering. At the same time, orchid leaves should be arranged to cut off diseased and withered leaves.
