Cultivation method of epiphyllum picture

Soil: it can be cultured with rotten leaf soil, garden soil and sandy soil. Fertilization: can apply rotten organic fertilizer, calcium superphosphate, ferrous sulfate solution and so on. Watering: in the low temperature season, to keep the basin soil in a dry state, the amount of water can be increased after the temperature rises. Light: cultured in shade, the suitable growth temperature is about 21 ℃-24 ℃. Change the basin: the young plants should change the basin once a year, and the formed plants should change the basin every 2-3 years.

1. Soil

1. Epiphyllum is suitable to be planted in slightly acidic sandy soil rich in humus, loose, fertile and well drained. The proportion of basin soil is rotten leaf soil: garden soil: sandy soil = 4:4:2.

2. After the basin soil is prepared, it can be exposed and sterilized in the sun, and when planting, put a layer of broken tiles or bricks at the bottom of the basin, which is beneficial to increase air permeability and drainage.

II. Fertilization

1. Epiphyllum prefers fertilizer. It is better to apply rotten organic fertilizer, and then add a small amount of bone powder or superphosphate. During this period, it should be mixed evenly with basin soil.

2. After topdressing the new stem in spring, if it is found that the leaves turn yellow during the growth period, the ferrous sulfate solution can be applied once, and 1000 times potassium dihydrogen phosphate can be applied once after the flower bud, and the flower can be withered every 20 days or so. The application of phosphorus and potassium fertilizer should be increased once, and fertilization should be stopped at the end of autumn.

Third, watering

1. Epiphyllum is afraid of waterlogging. When the temperature is relatively low in late autumn, winter and early spring, epiphyllum will be in a semi-dormant state. At this time, the amount of watering should be strictly controlled to make the basin soil in a dry state.

2. After the temperature rises in spring, epiphyllum will begin to grow again, and during this period, the amount of water can be gradually increased to keep the soil moist. In the period of vigorous growth, besides watering, it is necessary to sprinkle water around the plant, which is helpful to increase air humidity and strengthen ventilation.

Fourth, lighting

1. Epiphyllum does not have a high requirement for light, so it is more suitable to grow in a semi-shady and warm environment. In summer, it can be cultured in a shaded place, or in a place where there is no direct sunlight.

2. The suitable temperature for growth in spring and summer is about 21 ℃-24 ℃. It should be cultivated in greenhouse in winter and given full sunshine treatment, which is beneficial to flowering.

5. Change the basin

1. The young plants of epiphyllum should change their pots once a year, and the forming plants should change their pots every 2-3 years. The pots can be changed when the temperature is above 12 ℃ in spring or in September.

2. Stop watering before changing the basin, make the soil dry and take it off the basin gently, so as to avoid touching the plant, remove the old soil outside the root, then trim the dead root and cut the root, place it in a semi-shaded place after planting, and wait for 2 days to water slightly to keep the soil in the basin dry.
