1、 Improper moisture

Reason: during the growth process of maple, it needs reasonable watering to maintain the growth demand. Improper water will lead to fallen leaves. Excessive watering will lead to wet basin soil, promote root rot and fall leaves. If the watering is too little, the basin soil will be very dry, unable to absorb water, and it is difficult to maintain good growth. There is no water supply on the plant, which will also lead to defoliation

Measures: apply water reasonably to ensure that the demand for growth can be maintained. When there is too much water, it is necessary to promote the discharge of water. If there is too little water, it is necessary to water properly

2、 Improper fertilization

Reason: fertilizer is also an important point. Too much or too little fertilizer will do great harm to maple, and will also cause plant defoliation

Measures: fertilize according to the growing season and growth trend. If the fertilization is too much or too little, it needs to be adjusted in time

3、 Infectious diseases and insect pests

Reason: if you don't pay attention to maintenance during the growth process, you may be infected with diseases and pests, resulting in leaf loss

Measures: pay attention to ventilation for potted plants raised at home, find out the source of the disease and treat it in time

4、 Light discomfort

Reason: on the one hand, irradiance can also cause fallen leaves

Measures: give reasonable light and place it in a place with bright light
