1. Water control: its root system is very weak, unable to withstand the excessive water, the root burden is too large, resulting in suffocation. Similarly, if water is omitted, the leaves may droop and then fall. These two kinds of situations need to control the degree of watering well. When there is more water, control it. When there is less water, make up the watering.
2. Control fertilization: if the fertilizer is too thick or the raw fertilizer is not mature, the plant will be damaged by fertilizer. At the beginning, it will only turn yellow slightly, and then the leaves will fall off in large quantities. The application of water can be increased to ensure that water can flow out from below, so that it can be well remedied. When necessary, we need to turn over the basin to change the soil.
3. Keep acid: if water is applied to the basin for a long time, the basin soil will inevitably become alkaline. It can be properly applied with some alum fertilizer water to reduce its pH value, so as to create a suitable living environment for it
Defoliation may be caused by unreasonable application of water and fertilizer, or pH value change of flower soil. In addition, it may be that the light is not given correctly, which can be adjusted as soon as possible.
