Winter maintenance of Fusang: appropriate fertilization

Potted Fuso likes loose, fertile and slightly acidic soil with good drainage, but the temperature is low in winter, and the demand for fertilizer is reduced accordingly. Therefore, fertilization should be controlled from October. A thin layer of dry fertilizer can be sprinkled on the surface of the basin soil, such as coarse-grained cake powder, sauce residue powder, etc. We should reduce the application of nitrogen fertilizer to avoid excessive growth of branches and leaves, which will affect physiological dormancy. If the leaves are yellowing, the concentration of watering can be 0. 3% ferrous sulfate aqueous solution to improve soil physical and chemical properties.  

Maintenance of Fusang in winter: control watering

During the winter in Fusang, the basin soil should be dry and avoid being wet. Therefore, watering should be controlled to keep the basin soil slightly wet. Generally, water should be watered every 5-10 days, and the amount of water should not be too much, so as to avoid root rot caused by low temperature and high humidity soil environment. The northern winter climate is dry, and the leaf color is light yellow and the leaf edge is dry. Therefore, we should pay attention to improving the indoor air humidity. Spray washing branches and leaves or covering with plastic film can be used to increase the air humidity around the plant and create appropriate humidity conditions for its growth

Fusang winter curing: keep the temperature

The suitable dormancy temperature of Fusarium in winter is 5 ℃ ~ 15 ℃. If the room temperature is higher than 15 ℃, the plant can not get full dormancy, which is bound to affect the flowering of the next year; If the temperature is lower than 5 ℃, it is easy to suffer from freezing injury. In addition, pay attention to the water temperature when watering. The difference between the water temperature and the air temperature is too large (more than 5 ℃), which is easy to damage the root system. Therefore, the water for watering flowers should be dried for one day first, and then used when the water temperature is close to the indoor temperature.  

Maintenance of Fusang in winter: reasonable pruning

Pruning can adjust the tree shape, form a reasonable tree structure, control unnecessary nutritional growth and promote tissue enrichment. Therefore, the mulberry should be re cut at least once from half a month after entering the house to before leaving the house in the next spring. Generally, leave about 10cm for branches, and cut the rest of the branches short. After germination, select and leave 2 lateral branches on each branch, and cut off the other twigs

For older plants, extremely heavy short cutting can be carried out, that is, only 2 ~ 3 buds are retained at the base of each lateral branch, and all the upper parts are cut off. When pruning, pay attention to the internal and external orientation of the buds, so as to control the growth direction of the branches in the future

Fusang winter maintenance: pest control

After entering the house in winter, Fusang is vulnerable to aphids and scale insects if the indoor ventilation is poor and the light is insufficient. Attention should be paid to improving the ventilation and light transmission conditions of the indoor environment, combined with drug control. When a small amount of scale insects are found on the plant, it can be gently brushed off with a brush
