I. Causes of Leaf Drop in Radermachera sinica

1. Overwatering: Yellowing leaves are caused by prolonged rain exposure or excessive watering, which leads to excessively high moisture in the potting soil; the soil becomes oxygen-deficient and the roots rot.

2. Dry soil: Flowers dry out and yellow and fall off. This is caused by the pot soil being too full or by watering that does not penetrate for a long time. When watering, we must pay attention to keeping the soil moist and water appropriately.

3. Lack of fertilizer: Yellowing leaves are sometimes also related to root fertilizer. Applying too little fertilizer or not repotting for a long time causes the potting soil to lack nutrients. The nutrient supply to Radermachera sinica is insufficient, so the leaves turn yellow. Keep fertilizing and repot regularly.

4. Unsuitable light: Radermachera sinica likes light. If it is placed in a dark indoor place for a long time and cannot get light, it will also cause leaf drop due to insufficient light.

II. Solutions for Leaf Drop in Radermachera sinica

1. Watering: Watering twice a week is enough. When the potting soil turns white, it is time to water. If the potting soil is very moist, there is no need to water. Usually remember to loosen the soil often and control the frequency of watering.

2. Light: Radermachera sinica is a light-loving plant and can also tolerate partial shade. But in summer, do not let direct sunlight hit it; set up a shed for shade to avoid scorching the leaves. It is best to place it on a balcony or in front of a window. If placed in a dark indoor spot, it will cause leaf drop. In winter, try to let it receive more light.

3. Disease control: Strengthen indoor ventilation and air circulation, pay attention to controlling environmental humidity, and avoid water standing on the leaf surface for a long time. If a small number of diseased leaves are found, remove them promptly. You can spray 50% carbendazim wettable powder at 600 times dilution, for 3-4 consecutive applications, with half a month between each application. If live insects are found, wipe them off promptly with a cloth.
