Causes: 1. Overwatering. Although orchids prefer a humid environment, they should not be watered too much to cause root rot and dead leaves.

2. Less fertilizer or excessive fertilization. Less fertilizer will cause orchids to be malnourished and wither; Excessive fertilization will cause seedling burning and leaf withering.

3. Excessive lighting. Orchids are shade-loving and yang-phobing flowers.

4. The humidity is too low. Orchids require humidity to be between 60 and 80 percent, and if the foundation is too dry, it will cause leaf withering.

5. Low temperature. Orchids are suitable for living in warm environments, and low temperatures or freezing can cause the orchid to wither.

6. Suffering from diseases or encountering pests.

7. Failure to change pots and soil in time. Generally, orchids should be repotted and changed once in about 2 to 3 years.

Orchids belong to the more delicate flower species, and the dead leaves of orchids generally have the following reasons:

1. Overwatering. Although orchids prefer a humid environment, they should never be overwatered, otherwise it will lead to root rot and dead leaves.

2. Usually less fertilizer or excessive fertilization. Less fertilizer will cause orchids to be malnourished and withered, and excessive fertilization will cause seedlings to burn and die leaves.

3. Excessive lighting. Orchids are yin-loving and sun-phobing flowers, and excessive light is contraindicated.

4. The humidity is too low. Orchids require humidity between 60-80%, and if they are too dry, they will have dead leaves.

5. Low temperature. Orchids are suitable for survival in warm environments, and low temperatures or freezing can cause the orchid to wither or die.

6. Suffering from diseases or encountering pests will cause the dead leaves of orchids to die.

7. Failure to change pots and soil in time. Generally, orchids need to be repotted and soiled once in about 2-3 years.

8. Whether there is air pollution in the environment where orchids are cultivated. Orchid is one of the indicator flowers of air pollution, very sensitive to air pollution, such as oil smoke, soot, soot, paint, air fresheners, chemical synthetic agents, pesticides, etc., a little carelessness will lead to the orchid dead leaves or even die.

It can live, as long as the roots are not dead, and the orchid leaves are divided into the center of the leaf, the middle of the leaf, the front end of the leaf, and the tip of the leaf according to the part. Let's divide it into two parts, the first part is the middle of the leaf, the tip of the leaf, and the second part is the center of the leaf.

The first part of the leaves is rotten, relatively easy to handle, cut off the rotten leaves, the distance between the cut and the rotten leaves is at least one centimeter, don't be reluctant, cut down more, and then smear the sealing and sterilizing drugs at the cut to avoid water infection, and put it in a place with astigmatism and ventilation. This is not the end, we have to further observe the growth of orchids, especially the rotten leaves, if the rotten leaves continue to deteriorate, then we have to check again from the roots of the orchid, if the roots are also problematic, we must further treat the roots.

The second part of Ye Xin's heart is rotten, and then it will be a big trouble. When I first raised orchids, this was the problem. Leaf heart rot generally occurs on new shoots, the appearance is that the leaf heart is black, gently plucked with the hand, the leaf will fall.

If so, be careful, it is a bacterium that is caused under certain conditions and can spread to other new strains. At this time, the time has come for you to bother and labor, and you should spray 500 times of 50% carbendazim wettable powder for treatment. If it is seriously rotten, it needs to be turned over for disinfection and sterilization, and re-potted and planted.
