Pot soil for potted epiphyllum should be sandy soil with good drainage. You can put some bone powder at the bottom of the pot, or put horseshoes as base fertilizer, and apply thin oil cake water several times before and after flowering. The optimum wintering temperature is about 65438 05℃. At the same time, we should also pay attention to the following points: requirements for potted soil: loose, fertile, well-drained slightly acidic sandy loam with more humus should be used to cultivate epiphyllum. It can be prepared from 3 parts of coarse sand, 3 parts of humus soil or peat soil, 3 parts of garden soil and 1 part of organic fertilizer. Add a small amount of calcium superphosphate or bone meal acid agent, and mix well before use.

Cultivation temperature: the most suitable temperature for epiphyllum is 13 ~ 20℃, so the high temperature in summer should be placed in a well-ventilated semi-shady place, not in direct sunlight. It should be kept at about 65438 00℃ in winter. Too low temperature affects the formation of flower buds and makes it difficult to overwinter. Too high temperature will sprout new stems and branches, consume nutrients, and also affect the formation of flower buds and the next year's flowering.

Proper watering: Epiphyllum is suitable to grow in a slightly humid and stagnant environment, and the amount of watering depends on the season. When the temperature is low in winter, water should be controlled, and it is not advisable to dry too much, and the amount of water should be increased in spring. In the summer growing season, water should be fully watered to meet the needs of the growing season. But watering should master the principle of dry and wet, and water can't last long. Watering time should be in the morning and evening, pay attention to watering in bud stage to avoid falling buds.

Appropriate fertilization: the type of fertilization should be low-nitrogen and high-potassium compound fertilizer, and it is not suitable to apply a large amount of nitrogen fertilizer. It is necessary to adhere to the principle of "small amount and multiple times", and it is not appropriate to apply concentrated fertilizer to avoid the harm of fertilizer to plants. Generally speaking, it is appropriate to apply 1 times of fully decomposed diluted fertilizer and water every half month during the growth period. After budding, nitrogen fertilizer should be stopped and more bone meal or calcium superphosphate should be applied to promote more flowering. Nitrogen fertilizer should be applied in 1 ~ 2 times after flowers wither. Fertilization is not suitable when the temperature is low in winter or high in summer.

Pruning and shaping: the branches of epiphyllum are soft. Generally, bamboo sticks can be used to tie brackets in the basin to fix the stems and branches to form different shapes. This can not only improve the ornamental value, but also avoid the branches blocking each other and affecting the air permeability. When the stem of epiphyllum grows to a certain number, it should be properly controlled. The new buds at the base can be cut off, and the thin new branches at the top of the flower stem should also be removed. These weak stems are generally underdeveloped and cannot reproduce buds.
