African Jasmine cultivation methods and precautions
Today's editor will explain the relevant content of family flower cultivation of African Jasmine, including the cultivation methods and precautions. Let's introduce it next.
African Jasmine is a plant that is very popular among flower growers, with its full plant shape and lush green leathery leaves, it has become a popular indoor ornamental leaf plant in recent years. But how to cultivate African Jasmine?
African Jasmine grows well in warm climatic conditions, with an optimal growth temperature of 18°C to 32°C. When the temperature exceeds 38°C in summer, it will inhibit the growth of the plant; in some parts of South China, it can be planted outdoors and overwinter; while in areas north of the Yangtze River, potted African Jasmine requires a greenhouse temperature of no lower than 3°C to 5°C in winter, at least above 0°C, otherwise it is prone to frostbite on leaves and tender shoots.
Cultivation methods and precautions for African Jasmine:
1. 【Soil】 For cultivating African Jasmine in the south, the planting site should have loose, fertile, and well-drained sandy loam soil. For potted African Jasmine in the north, it can be mixed with 7 parts of decomposed leaf soil, 1 part of river sand, 1 part of decomposed organic fertilizer, and 1 part of fermented sawdust. Loosen the soil once a month during the growing season to keep the roots in a well-ventilated state. Additionally, change the soil for potted African Jasmine every 1 to 2 years.
2. 【Fertilizer】 Apply a dilute decomposed cake fertilizer water once a month during the growing season, and apply a phosphorus-potassium fertilizer before flowering in May to promote blooming; in autumn, supplement with 1 to 2 applications of phosphorus-potassium fertilizer to ensure safe overwintering. In the north, add 0.2% ferrous sulfate to the fertilizer water during the growing season to prevent leaf yellowing. When planting, apply enough base fertilizer, and in late autumn, apply cake fertilizer around the root system, about 0.5 to 1 kilogram per plant.
3. 【Temperature】 African Jasmine grows well in warm climates, with an optimal temperature of 18°C to 32°C. When the temperature exceeds 38°C in summer, it will inhibit the growth of the plant. In some parts of South China, it can be planted outdoors and overwinter, while in areas north of the Yangtze River, potted African Jasmine requires a greenhouse temperature of no lower than 3°C to 5°C in winter.
4. 【Light】 African Jasmine loves sunlight, with its native environment often being semi-shaded. In South China, when planted as a garden tree, it is best to choose a location with side shade; in areas north of the Yangtze River, it can receive full sunlight in spring and autumn, but requires shading in summer, or moving it under the dense shade of a tree, at least avoiding direct sunlight for several hours around noon. It is particularly important to note that after prolonged rain in June and July, when the temperature suddenly rises and sunlight is very strong, proper shading must be done to prevent the young tender shoots and leaves from being scorched. For potted African Jasmine in public places, there should be sufficient scattered light, or placed near a window, not too dark, otherwise it will cause the leaves to lose green, turn yellow, or fall off.
5. 【Water】 Whether planted in the ground or in a pot, African Jasmine requires sufficient water, but the roots should not accumulate water, otherwise it is prone to root rot. Watering in spring and autumn should keep the potting soil moist; be cautious of waterlogging during the plum rain season; in the hot summer, spray water twice a day, morning and afternoon, to increase humidity and cool down; in winter, for indoor potted African Jasmine, keep the potting soil slightly moist, and spray water on the leaves around noon when the temperature is relatively high. In spring, summer, and autumn, if the lower leaves of potted African Jasmine turn yellow and fall off under normal fertilization, it is likely due to waterlogging and root rot, and it is necessary to change the potting soil in time; in summer, if the new tender shoots wilt due to insufficient watering, do not immediately pour a lot of water into the potting soil, but first spray some water on the leaves, and then water the potting soil with an appropriate amount of water after the leaves have slightly recovered.
Precautions: If the African Jasmine at home is a bagged seedling or ground-planted seedling purchased from the south during the autumn and winter of the same year, special attention should be paid to winter frost protection. When strong cold air from the north comes south and there is a significant drop in temperature, heating should be provided in the greenhouse using electric heaters, radiators, or coal stoves to ensure the greenhouse temperature does not drop below 5°C, otherwise the plant may not recover from frostbite for a short period of time the following year. For a small number of potted plants placed in offices or living rooms, in addition to using double-layer plastic bags, the air conditioner or heater can be turned on at night, and one should not be careless.
