The soft and fertile sandy loam with good drainability should be used, and the neutral soil is the best. The soil of banana is a mixture of rotten leaf soil, culture soil and coarse sand. It is better to add a small amount of compound fertilizer as the base fertilizer in the culture soil. The base fertilizer can be sprinkled into the basin soil at the time of potting.
Zhu Jiao is extremely sensitive to water, so it is necessary to keep a certain humidity during its growth. Lack of water will cause the leaves to fall, too much water will cause water in the basin, which will cause the leaves to turn yellow and fall. During the growing period, water should be sprayed frequently, and the humidity is mainly 50-60%. In the growing season, the banana should be watered adequately. In the dry season and hot summer, it needs to be watered every day. In order to keep the humidity, it needs to spray water on the leaf surface.
The suitable growth temperature of banana should be between 20-25 ℃, the daytime temperature in summer can reach 25-30 ℃, and the winter temperature is relatively low, which should be kept between 7-10 ℃. Remember that the temperature should not be lower than 4 ℃, and individual varieties can withstand the low temperature environment of 0 ℃, which shows that the growth adaptability of banana is relatively strong.
Zhu Jiao likes light. In the northern area, it can be maintained in the indoor half light place or in the outdoor shade in spring and autumn. In winter, the temperature is low and the illumination is weak. It can be directly placed in the sunny place indoors to reduce the watering of plants and stop fertilization. The winter temperature should be higher than 10 ℃.
The fertilizer should be applied every half a month during the peak growing season. Too little fertilizer will also lead to the growth of banana leaves dim, thin, serious and even yellow withered leaves, thus affecting the growth and viewing of banana.
Zhu Jiao is often plagued by leaf spot and anthrax. Therefore, when encountering these two kinds of hazards, you can spray with antimicrobial solution, and when encountering scale insects, you can spray with 40% Omethoate 1000 times solution.
