In the growth period of light and temperature, it should be placed in a sunny place outdoors or in a greenhouse, which needs sufficient light. Go into the room in winter and cover it in a sunny place. It would be better if it were cultivated in a greenhouse. If the indoor temperature is kept above 65438 02℃ in winter, potted soil can survive the winter safely at 7-8℃. Water, fertilizer, spring and autumn are vigorous growth periods, so it is necessary to fully water and keep the basin soil moist, but not too wet. Water should be dry and wet, dry and thoroughly watered. The temperature is low in early spring and late autumn, so water should be controlled. Reduce watering in winter, keep the soil dry, and water it if it is too dry. Do not need too much fertilizer, apply dilute liquid fertilizer 1-2 times a month during the growing period, and stop fertilization in winter. Desert roses prefer phosphorus and potassium fertilizers, which are usually supplemented once a month or so. In summer, there should be enough fertilizer and water in the vigorous growth period, so that flowers can flourish and be bright. In addition, combined with changing the pot once a year, some long-term base fertilizers, such as rotten bean cakes and bone meal, can be appropriately applied in the pot. Pot fern desert rose pot soil? There is a vendor selling hay and other plants in the street. The vendor introduced the plant called desert rose to the guests. It is easy to feed, turns green after soaking in water for four to six hours, and produces beautiful flowers after three to five days. Flowers are shaped like roses, so they are named desert roses. Later, it was proved that desert rose is actually a fern called Selaginella, which is very drought-tolerant. In the dry season, it will turn yellow and wilt, just like hay. When the water supply is sufficient, the branches and leaves will stretch and turn green again, so it is also called "rejuvenation grass", but it can't actually bloom. & lt/SPAN>。 & lt/p & gt；
