What if the leaves of Phoenix tail bamboo turn yellow?

Phyllostachys pubescens is a variety of filial piety bamboo of the genus Gramineae, which is suitable for planting in the corner of the wall, corner and door of the courtyard. The smaller bamboo can be planted on the flower bed, can also make bamboo bonsai, and is also planted in the temple garden. It is also widely used as a material for low hedgerows in the south. Let's take a look at how the leaves turn yellow.

Sunlight exposure

Phyllostachys pubescens likes a semi-shady environment. If the sun is too strong, it will accelerate the evaporation of water in the leaves of Phyllostachys pubescens, causing the leaves to wither and yellow. However, if Phyllostachys pubescens is placed in a shady environment and there is no light for a long time, it will result in lack of chlorophyll, yellowing or even shedding of leaves, sufficient light in the half-shaded part of the window, no strong direct sunlight, and good ventilation, so it is necessary to move the bamboo to the semi-shade. In general, in spring, autumn and summer, Phoenix tail bamboo is placed in the ventilated place of the window and in the sunny place in winter.

Lack of nutrition

If Phyllostachys pubescens lacks nutrition in the process of growth, especially the lack of fertilizer, it will also lead to yellow leaves. At this time, it can be properly fertilized and watered. Lack of phosphate fertilizer or excessive fertilization in the soil will cause the leaves of Phyllostachys pubescens to be withered and yellow, and the lack of phosphate fertilizer will be fine.

Long-term fattening

There is no application of ammonia fertilizer or no change of soil for a long time, and there is a lack of nitrogen and other nutrients in the soil, resulting in thin branches and leaves and thin and yellow leaves. It is necessary to pour the pot in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer into new loose and fertile culture soil. Overfertilizing. If you fertilize too much, the new leaves will be thick and uneven, and the dry tips of the old leaves will fall off. You should immediately stop fertilization and increase the amount of water to make the fertilizer flow out from the drainage hole at the bottom of the basin, or immediately pour the pot, rinse the soil block with water and then plant it again into the basin.

Moisture aspect

Phoenix tail bamboo lack of water, the leaf edge or leaf tip will appear dry and yellow, or even shedding phenomenon, at this time should be timely watering, but watering should not be too much, once thoroughly to keep the basin soil moist, will cause rotten roots, leaves are water yellow, need to loosen the soil and blow dry water. If the leaves are water-yellow, especially the young leaves are relatively small and no longer grow up, it means that there is too much water in the soil, and it is necessary to loosen the soil and blow dry. If the leaf edge or leaf tip is dry and yellow, or even the leaf is shedding, it shows that it is caused by the lack of water in the soil and needs to be watered in time.

Disease and insect damage

The leaf spot disease caused by fungi and other bacteria is easy to cause local necrosis of the leaves, yellow spots or patches appear, the whole leaves wither and fall off seriously, the leaves are mottled with yellow and green after being infected by mosaic virus, and are damaged by shell insects, red spiders and so on. the leaves will also become local yellow, or even the whole leaves will wither and fall off. All should be sprayed in time.
