There are two methods of propagation of beauty cherry, namely sowing method and cutting method. The sowing time is in spring and autumn, after the seeds are vernalized at low temperature, they are wrapped with wet paper towels to germinate, and when they are white, they are scattered in fertile soil at high speed and covered with fine soil. Cuttage time is usually in May-June, cut a section of branches as cuttings, insert them into the wet sand bed, appropriate shade waiting for rooting.

1. Nutrient supplementation

If the umbrella does not get enough nutrients for a long time, the plant will develop poorly, resulting in the phenomenon of yellow leaves.It is necessary to supplement the plant with fertilizer, usually nitrogen fertilizer, which is very helpful for the growth of leaves.But also pay attention to the concentration of fertilizer, otherwise it will lead to excessive growth of plants.

2. Enhanced illumination

The big leaf umbrella cannot grow in a dark place, otherwise it will not be able to carry out photosynthesis and synthesize nutrients because of insufficient light, resulting in the phenomenon of yellow leaves.In this case, it is necessary to move it to the sunny place in time so that it can fully see the light, but also to avoid being exposed to the sun.

3. Watering and Acidification

If the soil is alkaline, or if it is often watered with alkaline water, it will also cause the plant to yellow, thus making the leaves yellow.In this case, it is necessary to add a proper amount of ferrous sulfate when watering, which can have the effect of acidification, or apply a little alum fertilizer water to it, which can also effectively improve the acidity and alkalinity of the soil.

4. Appropriate cooling

Big leaf umbrella is afraid of strong light and high temperature, long time exposure to the sun, will also lead to yellow leaves.Usually, the plant is placed in a semi-shady place, sprayed with water around it, and the purpose of cooling is achieved through evaporation of water.In addition, good ventilation should be maintained to avoid bacteria breeding in high temperature and humidity environment and causing various pests and diseases.
