What happened to the cracking of the latest orchid leaves?

Orchid is a kind of flower plant with high ornamental value, which is welcomed by many people in our country. Now many people like to raise some orchid potted plants and put them at home for viewing. So now the planting area of orchids is still relatively large, but whether it is family maintenance or large-scale planting. The phenomenon of leaf cracking often occurs in the process of orchid planting, so what about the cracking of orchid leaves? Let's take a look at it.

1. Insect pests

Orchids will be threatened by pests in the process of growth, some pests will take the leaves and flowers of orchids as food, seriously affecting the growth of orchids. The most common pest in the growth period of orchids is scale insects, and the main symptom caused by scale insects to orchids is to cause leaves to crack. Because scale insects eat leaves from the inside out, the leaves will crack in the early stage. Therefore, we should pay attention to check the growth of orchids frequently, and if scale insects are found, we should control them in time. It is necessary to create a permeable environment for orchids and reduce the harm of pests.

2. Disease

Orchids will be harmed by insect pests, and naturally they may also be disturbed by diseases. There are many common diseases in orchids, such as leaf spot, downy mildew and so on. The main symptoms of common diseases of orchids are spots on the leaves, resulting in lack of water and drying up of the leaves, and gradually cracking in the middle of the leaves. Therefore, while we are preventing and controlling insect pests, diseases also need our attention. We should have some understanding of the common diseases of orchids, so that we can find out the specific diseases in time when the disease occurs. Then prescribe the right medicine to the case, and the condition is aggravated, which leads to the aggravation of leaf cracking.

3. Fertilizer damage

Although orchids need proper fertilization in the process of growth, they also need the supply of nutrients in fertilizer. However, when we apply fertilizer, we should pay attention to control the amount of fertilizer, if the fertilizer is insufficient, then the orchid will grow because of lack of nutrition, and the leaves will be yellowed, withered, cracked and so on. Fertilizer should not be too much, if too much fertilizer is applied, it is also very easy to cause the leaves to crack. At the same time, we should also be careful not to let the leaves touch the fertilizer directly, otherwise the leaves are easy to be burned by the fertilizer. Therefore, we should pay attention to rational fertilization to ensure the normal growth of orchids.

4. External factors

In addition to the above three, there are also some external factors that lead to the cracking of orchid leaves. For example, when planting personnel are watering, fertilizing and pruning, it is possible for improper operation to lead to leaf cracking. And if it is scoured by Rain Water or Rain Water is too large, there is a high probability that the blade will crack. Therefore, when planting, it is necessary to ensure that the orchid is in a place with good shelter from wind and rain, and when fertilizing, do not let the fertilizer touch the leaves directly to prevent the leaves from being burned.

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