Causes of Yellowing Leaves in Wampee and How to Prevent and Treat Them

Wampee is a fruit with a rich aroma and intense flavor. It prefers a warm, humid environment, and in China it is currently grown mainly in the south. However, during the cultivation of wampee, yellowing leaves occur very easily. Once the fruit tree shows yellowing leaves again, the nutrients produced by photosynthesis are insufficient, which can seriously affect the growth and development of the tree. It may fail to sprout for a long time and may even cause a drop in yield. So what causes yellow leaves in wampee? Let us take a look together.

I. Causes of Yellow Leaves

1. Insufficient nutrients

We all know that plant leaves are green, and this green color comes from chlorophyll, that is, chloroplasts, which are important substances for plants to carry out photosynthesis. The chloroplasts in the leaves also contain protein components. When nitrogen is deficient, the protein content in the leaves decreases, which in turn reduces chloroplasts and causes yellow leaves in wampee.

2. Excessive water accumulation

During the cultivation of wampee, because of excessive water accumulation, the root system can suffocate and rot. The young, tender roots are especially prone to rotting. Once the roots lose their ability to absorb nutrients, over time, after the nutrients in the leaves are used up, the leaves will gradually age, fade and turn yellow.

II. Prevention and Treatment Methods

1. Strengthen fertilizer and water management

During the cultivation of wampee, topdressing should be carried out from time to time according to different growth conditions. Use well-rotted farmyard manure as the main fertilizer, and reasonably combine it with microbial fertilizer and compound fertilizer. Of course, the type of fertilizer applied still has to be decided according to the growing environment. For example, on dry sloping land, in addition to supplementary fertilizer, the most critical thing is still to water to keep the soil moist for a long time, ensuring sufficient fertilizer and water and providing the roots with adequate nutrients.

2. Dig ditches for drainage

Water accumulation is often caused by poor drainage, so make sure that on rainy days the water level in the drainage ditch is at least 20 cm above the ground level at the roots. If water remains for a long time, dig it even lower. This is mainly because wampee fears water, so after rain it is essential to drain promptly. When watering normally, do not use too much either; it is recommended to water frequently in small amounts and just keep the soil moist. As long as drainage is done properly, there will be no root rot caused by water accumulation, and there will be no yellow leaf symptoms either.
