1、 Improper watering
Longchuanhua likes a humid environment. If there is a lack of water, it is easy to affect the development of the plant, and then the leaves will fall off. At this time, you need to water immediately, but don't water too much. If more water is poured, there will be accumulated water in the soil, which will inhibit the respiration of the root and make it lose its leaves. At this time, it is necessary to drain the excess water, loosen the soil properly, maintain good ventilation and accelerate water evaporation p>
2、 Insufficient light
Longchuanhua is suitable for growing in an environment with sufficient light. If the environment is dark, the plant cannot receive light for a long time, and the leaves will fall off. Usually put the plant in a sunny place, but it needs proper shade at noon in summer to prevent the plant from being exposed to the sun. In winter, you can bask in the sun all day, because the light is softer at this time, which is also helpful to improve the temperature p>
3、 Soil discomfort
Longchuanhua is suitable to grow in acid sandy loam with good drainage. If the soil is alkaline or sticky, it is often unfavorable for root respiration. At this time, the soil needs to be replaced. Generally, 1 part of garden soil is combined with 1 part of river sand and 1 part of organic fertilizer, which can be fully mixed. It can also be prepared with pond mud, river sand and coconut bran, and the ratio of the three is 2:1:1 p>
4、 Fertilizer surplus
If you fertilize longchuanhua too much, the fertilizer will damage the root system and then drop the leaves. In view of this situation, it is necessary to wash the basin soil with clean water to wash away the fertilizer in the soil. When fertilizing at ordinary times, it needs to be fully diluted to reduce the concentration of fertilizer. It can be applied every 30-40 days during the growth period, and fertilization should be stopped in winter p>
