If there is too little fertilization, the leaves will turn yellow if the plant nutrients are insufficient, but if the fertilizer is too thick, it will cause root burns, can not absorb nutrients and water, and will also lead to leaf yellowing.

Solution: Wenshu orchid applies base fertilizer before planting, and then rarely fertilizes, except that after entering the growing period, its demand for fertilizer soars, which basically needs to be fertilized once every two weeks. and in fertilization should also follow the principle of frequent application of thin fertilizer to ensure that the plant will not be burned.

Wenshulan likes the environment with plenty of light, but it is not resistant to strong light exposure, especially when the summer sun is strong, if it falls directly in the sun, it will cause burns due to excessive light, resulting in yellowing leaves.

Solution: when the temperature is relatively suitable in spring and autumn, we can put it outside to receive sunshine all day, but when the light is too strong in summer, we'd better keep it in a cool environment, and the light is weak in winter. Appropriate artificial lighting is needed.

4. Infection of diseases and insect pests

The damage of diseases and insect pests is also one of the reasons for the yellowing of Manjusri leaves, resulting in more yellowing diseases and insect pests, and in serious cases, it will cause the whole plant to die.

Solution: when the leaves of Wenshu orchid plants turn yellow because of diseases and insect pests, they need to be dealt with in time so as not to become more serious. in prevention and control, we should first identify which kind of disease according to the symptoms of diseases and insect pests, and then prescribe the right medicine to completely exterminate the disease.
