Jasminum nudiflorum is usually planted in the open or potted outdoor for maintenance. It can also grow normally in the wind and rain. Especially in the rainy season, the drainage of the soil is poor after the rain, the water in the basin is not removed in time, and the root respiration is blocked, thus affecting the growth of the plant.
In fact, there is no fixed time for watering each kind of flowers. The flower friends water according to their feelings. The air is dry and the temperature is too high, so they water more. This is wrong. Winter jasmine is afraid of waterlogging. Too much water will slow down the growth of plants, and the new branches and leaves will turn yellow.
The growth of Jasminum nudiflorum needs timely fertilization, otherwise it is really difficult to extract new branches and affect the growth of plants.
The main symptoms were small leaves, deformity, dark green spots or yellowing, no flowering or even smaller flowers.
Remove weeds in time, reduce the source of infection, and ensure the surrounding environment of Jasminum nudiflorum is clean. Secondly, control aphids and reduce transmission medium.
Correct watering, do not rely on the feeling, check the dry and wet conditions of the soil before watering, adhere to see wet and dry. If there is no proper measure, the amount of water can be effectively controlled by sun exposure immediately after watering, or by using soaking basin method. (the pot soaking method is to place the flowerpot in the water, so that the water does not exceed 2 /3 of it, and the water naturally enters the soil.)
When selecting soil, the loose soil with good drainage performance shall be selected. When entering the flowerpot, a layer of coarse sand shall be paved at the bottom of the flowerpot as the water resisting layer. The poor air permeability of the soil is found in the maintenance, and the basin shall be turned in time for soil replacement.
The winter jasmine peanut needs 2-3 times of top dressing for a long time, mainly nitrogen, phosphorus and potassium. When potted Jasminum flowers are potted, sufficient basal fertilizer should be applied. Before flowering, nitrogen fertilizer should be applied once. After flowering, prune the branches and leaves in time and apply fertilizer once. In the process of maintenance, fertilizer should be applied reasonably according to the growth of plants. Every time we irrigate thin liquid fertilizer, so as to avoid fertilizer damage caused by excessive fertilization.
