What to do when the leaves of the orchids turn yellow, apply thin fertilizer/control the amount of watering/avoid strong light

Wenshu orchid is a kind of highly ornamental flower plant, which can not only be potted, but also can be planted in a large area. However, no matter how high the ornamental plant, if the leaves turn yellow, it will also affect its overall beauty. What if the Manjusri leaves turn yellow? Next, the editor will take you to learn about it.

First, what if the leaves of Wenshulan turn yellow? find the reason.

If we want to know what to do when the leaves of Wenshu orchid turn yellow, we must first understand what causes it. Only by finding the cause can we solve the problem pertinently. Such as improper watering and fertilization, too strong light may cause this phenomenon, as for the specific solutions are described in detail below, let's take a look.

2. The treatment of yellowing of Wenshu orchid leaves.

1. Improper fertilization and frequent application of thin fertilizer

Fertilizer is one of the main nutrients of Wenshu orchid, but it is more fastidious when applying fertilizer, if it is applied too little, it will make the leaves yellow because of insufficient nutrients, and it is easy to burn plants if thick fertilizer is applied directly.

Solution: after entering the growing period, Wenshu orchid has a high demand for fertilizer, which basically needs to be fertilized every two weeks, and we should follow the principle of applying thin fertilizer frequently when fertilizing it, and the fertilizer must be diluted before fertilization.

two。 Improper watering, control the amount of water.

In the process of cultivating Wenshu orchids, watering is also a point that needs to be paid attention to. If too much watering causes stagnant water, it is easy to cause rotting roots, and if too little watering, it will also cause Manjusri leaves to turn yellow, so the frequency of different seasons is very important.

Solution: the water demand of Wenshulan is different in each period. Before sprouting, we need to keep the soil as moist as possible. After its budding, we need to gradually reduce the amount of water and keep the soil surface as dry as possible. This can prevent diseases and insect pests to a certain extent.

3. The light is so strong that it is kept in the semi-shade in summer.

Wenshu orchids prefer light, but they are not tolerant to strong light, especially when the summer light is relatively strong, if we cultivate it directly in the sun, it will burn the plants because the light is too strong, thus causing the leaves of Manjushri to turn yellow.

Solution: when the light is more suitable in spring and autumn, we can keep it outside and let it receive light all day. However, when the summer sun is too strong, it is best to move it to the indoor semi-shade for breeding.

4. Do not delay timely prevention and control of diseases and insect pests

The emergence of diseases and insect pests is also one of the reasons for the yellowing of Manjusri leaves, many diseases and insect pests will cause this phenomenon, and in serious cases, it will also lead to the phenomenon of plant death.

Solution: if this phenomenon is caused by diseases and insect pests, then we must deal with it in time, because the longer the time drags on, the more difficult it is to prevent and cure. As for the specific treatment methods, the editor has introduced the pest control of Wenshulan, which we can learn about.
