What if the leaves of Luohan bamboo turn yellow

To say that the leaves of Luohan bamboo turn yellow, in addition to environmental discomfort, it is caused by improper maintenance: if the light is too strong, it needs proper shading; if it is watered too much, it is necessary to loosen the soil, and when there are rotten roots, it needs to be cut off, and then the pot soil needs to be replanted; if the soil is caused by alkali, the basin soil can be changed; if it is caused by diseases and insect pests, we need to spray to prevent and control it.

2. The causes of yellowing of Luohan bamboo leaves and its solutions.

1. Environmental mutation

There are many reasons for the yellowing of Luohan bamboo leaves, and the first thing we should consider is the environment. Nowadays, everyone likes to buy pots of Luohan bamboo online, which can easily lead to large geographical cross-clothing and great changes in the environment. Luohanzhu can not adapt to the leaf yellow for a while.

Solution: very simple, according to the growth habits of Luohan bamboo, to provide its most suitable growth environment: sufficient astigmatism, slightly wet basin soil, environmental ventilation. After a period of time, the plant will return to health.

2. Excessive illumination

Luohan bamboo likes light and needs sufficient light in the process of growth, but it avoids strong light. Once it is directly exposed to strong light in summer, the chlorophyll in its leaves will be destroyed, and the tissue can not carry out normal photosynthesis. As a result, the leaves will slowly turn yellow.

Solution: in summer, move the bamboo to a cool and ventilated place in time, wait for it to slow down, and then slowly increase the light, after a period of time, the leaves will gradually turn green.

3. Improper watering

① insufficient watering: Luohan bamboo likes the humid environment, if the watering is too little, the leaves will naturally turn yellow if they do not get the supply of nutrients. Solution: replenish water in time, but don't water too much at once, just keep the basin soil slightly wet.

② overwatering: although Luohan bamboo likes water, it is afraid of stagnant water. once it is overwatered, causing stagnant water in the basin soil, it will be difficult for the roots to breathe, and the leaves will turn yellow because they cannot absorb nutrients. Solution: loosen the soil and let the water evaporate quickly; if the roots have been soaked, the plant needs to be removed from the pot, then cut off the rotten roots and replanted with hearty soil.

4. Soil alkali.

According to the growth habits of Luohan bamboo, we know that it likes slightly acidic soil, if the soil is alkaline, or long-term watering of mineral water leads to alkaline soil, the plant will grow poorly, resulting in leaf yellow symptoms.

Solution: very simple, if the soil is caused by alkali, you can replace the basin soil. Remove the plant from the pot, then replace it with humus soil, pastoral soil, tree soil and fine sand in the ratio of 2 to 1, and then replant it.

5. Diseases and insect pests

In addition to the above points, the yellowing of Luohan bamboo leaves may also be caused by diseases and insect pests. The common diseases and insects are shell insects, which are mainly attached to the surface of the leaves and absorb nutrients in the leaves, so the leaves turn yellow and wither. Solution: a small amount of pests are directly removed manually, and a large number of them are sprayed with liquid medicine in time. For specific drugs, you can refer to the treatment of diseases and insect pests of Luohan bamboo.
