The leaf shape of Clivia is first determined by the variety. In your case, the room temperature is low in winter and suddenly rises in spring, causing several leaves to grow together. Lighting generally requires bright scattered light, not strong light, and leaves are easy to burn.
① Soil: Clivia is suitable for soil rich in humus, with good air permeability, good water permeability, fertile soil and slight acidity (PH6.5). In humus. Infiltrating about 20% sand particles is beneficial to root culture. Pots for cultivation are gradually increasing with the growth of plants, and 3-inch pots are suitable for cultivating annual seedlings. Change a 5-inch flowerpot in the second year,1change a bigger flowerpot in the next four years. Changing pots can be done in spring and autumn. ?
2 watering: Clivia has developed fleshy roots, which can store more water and has certain drought tolerance. Generally speaking, the soil moisture content is about 30%. After the surface is dry, water three pots of soil for 1 time in winter, 3 ~ 5 days, spring and autumn 1 time, 1 ~ 2 days, and appropriately increase the watering times in summer. Water is needed less in seedling stage and more in flowering stage. Don't water the leaves in case they rot. When dust is found on the leaves, you can gently wipe the leaves with a soft cloth or brush them with a soft brush. Don't wash them with a lot of water. ?
③ Fertilization: Clivia likes to fertilize, but too much fertilization will lead to rotten roots. In addition to applying base fertilizer, topdressing should also adopt the method of "thin fertilizer and more fertilizer" Apply base fertilizer when changing pots. Apply fermented solid fertilizer every other month in spring and autumn, and then apply liquid fertilizer once a week, preferably without topdressing. The whole plant can grow slowly by relying on the nutrients accumulated in spring and autumn. When applying solid fertilizer, dig up the pot soil and bury it in the soil to a depth of 2 cm, so as not to directly contact the root system to avoid scalding; When applying liquid fertilizer, it is appropriate to apply fertilizer: water 1: 40 for small seedlings and 1: 20 for large and medium flowers. It is more appropriate to fertilize in the morning to avoid splashing on the leaves. After applying liquid fertilizer, water 1 time in time, but not too much. On the one hand, it can dissolve the fertilizer, on the other hand, it can clean and rinse the newly grown fleshy roots. There are different kinds of fertilizers in different seasons. Apply phosphorus and potassium fertilizer in winter and spring, such as bone meal; Partial application of nitrogen fertilizer in autumn, such as bean cake water; Top dressing outside roots is commonly used in summer. Foliar spraying with 0. 1% potassium dihydrogen phosphate or calcium superphosphate can be carried out all year round. ?
④ Illumination: During the whole cultivation process, try not to expose the plants to direct sunlight. About four hours of scattered sunlight every day is enough. Excessive light will narrow the leaves. Clivia should avoid high temperature and scorching sun in summer, so it should be placed in a cool environment with high air humidity and pay attention to ventilation. Clivia is afraid of cold in winter, so it should be moved to a place with sufficient indoor light, and it can safely overwinter at room temperature of about 5℃. If conditions permit, it is best to keep the ambient temperature stable at 15 ~ 25℃.
