How is the leaf tip of an orchid blackened?

Orchid leaf tip blackening is also known as Jiaojian by orchid friends, and there are many theories about the causes of orchid scorched tip. This article is a senior orchid friend who summarized the reason for orchid leaf tip blackening according to his own experience.

I think the reason for the scorched tip of orchids is mainly caused by the metabolism of the plants themselves. For example, high humidity, suitable temperature and fast growth may be the reason why orchids are not scorched. The climate in the north is dry, so it is difficult to keep the orchids from scorching.

Therefore, the way to avoid the focal tip is to raise the root as well as possible, which can be done on the spring orchid, but it is very difficult for the cymbidium, because the leaves of the cymbidium are long, and the juice will leave some harmful substances in the leaf tip during the cycle. over time, it will cause the phenomenon of focal tip.

Of course, there are ways to avoid the scorched tip of Huilan as far as possible, thin and diligent, not to use too much fertilizer, so haste makes waste. Try to change the new plant material once a year, and gently rub the root under the old seedling with water each time, so that the harmful salts attached to the surface of the root bark will be removed and the orchid will come back to life.

If you want to make the orchids in the flower shed not scorched at all, you can add water curtains to increase air humidity, heat them in winter (15-30 degrees), and add some chemical elements that stimulate the rapid metabolism of orchids. But this not only violates the laws of nature, but also greatly reduces the stress resistance of orchids.

You can't have both a fish and a bear's paw, hehe!
