What should I do if the leaves of the umbrella tree turn yellow? Why do the leaves turn yellow?

1. Supplement nutrients

If the umbrella plant does not get sufficient nutrients for a long time, the plant will develop poorly and yellow leaves will appear. The plants need to be supplemented with fertilizer, generally nitrogen fertilizer, which is very helpful for leaf growth. But you should also pay attention to the concentration of fertilizer, otherwise it will cause the plant to grow too tall.

2. Enhance lighting

The umbrella plant cannot grow in a dark place, otherwise it will not get enough light, which will cause it to be unable to photosynthesize and synthesize nutrients, resulting in yellow leaves. In this case, you need to move it to a sunny place in time so that it can get enough light, but also avoid being exposed to the sun.

3. Watering acidification

If the soil is alkaline, or if alkaline water is frequently used for watering, it can also cause the plant to turn yellow, causing the leaves to turn yellow. In this case, you need to add an appropriate amount of ferrous sulfate when watering, which can have an acidifying effect, or apply some alum fertilizer water, which can also effectively improve the acidity and alkalinity of the soil.

4. Appropriate cooling

The umbrella plant is very afraid of strong light and high temperature. If it is exposed to the sun for a long time, its leaves will turn yellow. Usually the plant should be placed in semi-shade and some water should be sprayed around it to achieve the purpose of cooling through water evaporation. In addition, good ventilation must be maintained to prevent the high temperature and high humidity environment from breeding bacteria and causing various diseases and pests.
