What is the reason for the leaf roll?

Cymbidium is very popular in our country, and its planting area is still relatively large. Because the ornamental value is high, so many people like to maintain hanging orchid potted plants. However, whether it is family maintenance or garden planting, there are often some problems in the growth process. The curling leaf is one of them, so what is the reason that leads to the curling leaf of the hanging orchid? The following editor will give you a brief introduction, let's have a look!

1. Lack of moisture

Water is very important to the growth of Cymbidium, and it is also the main reason for rolling leaves. When planting Cymbidium, if the soil water content is insufficient and the soil is too dry because it has not been watered for a long time, then the plant will cause the leaves to turn yellow and roll because of the lack of water. Therefore, when we are conserving, we should pay attention to watering to ensure the water content of the soil. If the soil is dry for a long time, then watering should not be poured in large quantities at one time, and should be done step by step to avoid the fact that the orchid is unable to adapt and lead to counterproductive.

2. Lack of light

Light is also an indispensable environmental factor in the growth of Cymbidium. During the growth of the orchid, it is necessary to maintain an appropriate amount of light time and intensity every day. The light time should be kept at least 4 hours a day, if it is in a dark environment for a long time, it is very easy to cause the hanging orchid to roll its leaves. And the light should not be too strong, mainly scattered light, if the light is too strong, then it will cause the leaves to be burned. Therefore, we should provide an appropriate amount of scattered light for the orchid to maintain the normal growth of the orchid, neither less light nor exposure.

3. Improper fertilization

The growth of most plants is inseparable from fertilizer, and Cymbidium is no exception. Fertilizer is the main way for Cymbidium to obtain growth nutrition, but we should pay attention to control the dosage and frequency when applying fertilizer. If the fertilizer is too much, the orchid can not absorb all of it, resulting in the accumulation of too many nutrients in the soil, resulting in fertilizer damage, resulting in curling leaves. However, fertilizer should not be too little, too little fertilizer can not meet the growth and nutrition of Cymbidium, but also cause leaf curling phenomenon. Therefore, we should apply fertilizer reasonably according to the actual situation, if there is too little fertilizer, we should apply fertilizer in time, and if we have too much fertilizer, we should water and dilute it in time.

4. Soil causes

In fact, soil is also one of the main reasons for the curling leaves of Cymbidium. Cymbidium is suitable for growing in soil with high permeability, water and fertilizer conservation and rich nutrition. If the soil is hardened and the drainage is poor so that the stagnant water cannot be discharged, then the respiration of the roots is blocked, thus affecting the leaves, resulting in leaf curling. Therefore, when we plant the orchid, we should pay attention to do a good job of loosening the soil, control the amount of water and improve the quality of the soil. If it is a potted plant, then we should change the soil regularly to ensure the normal growth of the orchid.

The above is a brief introduction to what is the reason for hanging orchid curling leaves. That's all for today's introduction. This article is for reference only. I hope it can help you all.
