Maintain the soil quality of winter jasmine, and loose and slightly acidic soil with good air permeability. The first method of rapid growth is free range. Give full play to the advantages of relatively developed root system of winter jasmine. The flowerpot is padded with coarse sand or broken red clay bricks. Then cover with a layer of humus soil, 3 to 7 cm, and then cover with fine sand to isolate the roots from humus soil. The planted soil should be mixed with pastoral soil and thick humus sand at a ratio of one third each. In the early stage, Jasminum nudiflorum grows in the mixed soil, and the rhizome is developed in the middle and late stage, plus the nutrients provided by humus soil. Winter jasmine will grow quickly.
Winter jasmine should be kept in the position of natural ventilation and astigmatism, and it is best to isolate it for 5 to 7 hours in the morning, middle and evening. The growth temperature is between 15 and 30. The relative humidity of air reaches above 65%. Water the winter jasmine, observe the wet and dry conditions of the basin soil, and ensure that it is thoroughly watered if it is not done. Then apply spray method to replenish water to the branches and leaves. Improve the environmental humidity of the air.
In the case of free-range, winter jasmine should be irrigated with cooked bean cake fertilizer and farmyard manure. Give "nitrogen" as the main nutrient to promote the growth of branches and leaves. A small amount of "P-K" compound fertilizer can promote rhizome growth and improve disease resistance. When the trunk grows thicker, the branches on it should be removed, so that the trunk can grow and the nutrients can be driven to the trunk. With the growth of trunks, the joint positions between trunks also increase.
Lower the terminal buds and concentrate the growth on the trunk. The main pole can grow rapidly. Without the growth advantage of the top, it will provide a lot of nutrients and grow rapidly in a short time. In a word, the maintenance of winter jasmine is very high, so that its trunk can grow rapidly. Without careful maintenance, it is difficult to ensure its growth effect.
