Jinhuang Xingsheng should not be watered too much for a long time. Keep the pot soil dry. The pot soil is too wet. The stems and leaves are easy to grow in vain. The leaves and roots will start to rot and lose their ornamental value. Especially in the low temperature environment in winter, there is too much water, and the roots are easy to rot and die.
Do not water too much in high temperature in midsummer, or the plant will suffer from physiological water shortage, resulting in leaf wilting. When the balcony is maintained in the open air, it is forbidden to shower.
During the growing period, fertilizer should be applied once a month to keep the leaves clear and green. But the fertilization should not be too thick, which is harmful to the growth of plants. Excessive frequency of fertilization will lead to elongation of internode and affect posture. If the branches are too long or old, they can be cut short and fertilized to promote rejuvenation.
The thin fertilizer of "low nitrogen, high phosphorus and potassium" is generally selected for fertilization. During fertilization, pay attention not to splash the fertilizer water on the leaves, so as to avoid the formation of ugly spots, which is difficult to remove.
Jinhuangxing will enter a short dormancy period in summer, and the leaves at the base will basically slowly fall off, leaving only a few pieces at the top. At this time, the plant is in a slow growth stage. Water once a month, do not water thoroughly, just maintain basic life. Pay attention to sunshade and ventilation in high temperature.
The main diseases of jinghuangxing are leaf spot and rust. When it comes on, it is necessary to spray 2000 times of weixiangling wettable powder in time. The common pests are root knot nematode and black elephant beetle, which are killed by spraying 1000 times of 40% Omethoate emulsion. However, the possibility of pests in the family is relatively small.
In winter, put it in the sunny place, keep the temperature between 6 ℃ and 8 ℃, and control the watering, so as to prevent the rotten roots caused by low temperature and humidity. It is also not suitable to water too much in high temperature in midsummer, otherwise the leaves will be withered and fallen off due to root rot, and the ventilation will be strengthened to prevent torrential rain.
Turn the basin once a year in spring, and the basin soil shall be loose and well drained. One portion of rotten leaf soil, one portion of garden soil and one portion of coarse sand are commonly used. After mixing, they can be used, and a small amount of bone powder is added as the base fertilizer.
After 4 years of maintenance, the plants of jinhuangxing are easy to age, so it is necessary to cultivate new seedlings to renew the old plants.
