(1) Soil utilization and fertilization. Suitable for well-drained and nutritious soil. 2 parts of peat soil, coarse sand 1 part, slag 1 part can be selected for preparation, and peat soil, humus soil, sand and perlite can also be prepared according to the ratio of 4: 3: 2: 1. Fertilize once every half month in summer, and add phosphate fertilizer once when the buds are in full bloom in early summer. Too much fertilizer and water, too much shade, easily lead to long stems and affect flowering. Fertilizers are mainly decomposed cake fertilizer, diammonium phosphate and potassium dihydrogen phosphate. Stop watering and fertilizing after budding.

(2) moisture. Epiphyllum likes moist soil and high air humidity, and is afraid of waterlogging. Therefore, when plants begin to grow in spring, the principle of watering is to water the soil once after it is dry, and to water the fertilizer thinly between watering, instead of watering. In the season of vigorous growth in summer, water is usually poured once every two days, and water is sprayed on plants and the ground 1 ~ 2 times in the morning and evening to increase the air humidity. During the flowering period from July to August, keep the soil moist and avoid being too dry or too wet. It is not advisable to water too much in autumn, and then water the basin soil after it is slightly dry. Winter is dormant, so water should be controlled and the soil should be slightly dry.

(3) illumination and temperature. Sufficient light is the first condition to promote the flowering of epiphyllum, and it should be ensured all year round. The suitable temperature for growing period is 20 ~ 25℃, and the room temperature in winter should not be lower than 5℃.

(4) plastic trimming. The leaflike stems of potted epiphyllum are weak, so pillars should be set up. In addition, in the bud stage, the new buds on the deformed stems should be removed in time to concentrate the nutrients on the buds; Prune in time after flowering, remove old branches, and apply nitrogen fertilizer 1 ~ 2 times appropriately. Summer is a period of vigorous growth, so attention should be paid to pruning, thinning the weak buds at the top and upper parts of deformed stems, and retaining the strong buds at the middle and lower parts.

(5) pest control. Irrigation with 400 ~ 500 times potassium permanganate solution can prevent root rot. Pests such as snails and mealybugs can be caught manually or controlled with pesticides.
