Clivia should leave the room before and after Qingming

 spring is the best time for Cymbidium to grow, and the following conservation measures should be taken during this season:

 1. Come out of the room in due course. Temperate zones are generally around Ching Ming Festival, while cold areas have to be delayed for about half a month. You can also leave the room when the temperature is above 15 ℃.

 2. Change the pot ramets. The pot change is usually carried out after flowering in spring. If there are tillering buds at the base of the plant, and there are 3 ~ 4 leaves, and the plant height is more than 10 cm, it should be combined with changing pots. Magnolia is a fleshy root, which requires loose, fertile and well-drained soil, which grows best at a slightly acidic pH value of 6.2-6.0. The basin soil can be prepared by mixing rotten chicken manure and pond mud at 4:6 or by mixing pine needles, rotten chicken manure and river sand at 5:3:2.

 3. Water and fertilize. Due to the rising temperature in spring, the number of times and amount of water should be from less to more. The gentleman orchid likes to grow in a humid environment, the air relative humidity should not be less than 60%, and the leaf color is shiny. If the environment is dry, the leaves will be dull or even wilted, the leaves will be yellow, and the growth will not be good. Therefore, it is necessary to spray water to the leaf surface 2 ~ 3 times a day. But be careful not to make the water flow to the rhizome to prevent waterlogging of the basin soil. Rarefied liquid fertilizer is usually applied about 10 days after leaving the room, such as compound fertilizer should be applied at the edge of the basin, the quantity should be less rather than more.

 4. Promote buds and flowers. In order to avoid arrows entrapment caused by low temperature, the room temperature should be increased 2 ~ 3 weeks before arrow drawing, the amount of water should be increased, liquid fertilizer should be applied once every 7 ~ 10 days or compound fertilizer dominated by phosphorus and potassium should be applied once a month, and the indoor temperature should be kept at 10 ℃-15 ℃ as far as possible, so as to promote the plant to bloom at the right time.

 5. Control diseases and insect pests. The plants can be sprayed with 0.3-0.5 concentration of stone-sulfur mixture, once every 10 days, 2 ~ 3 times continuously.
