Is the withered leaves of orchids a disease? What's the basis?
People who raise orchids all want their orchid leaves to be dark green, but in fact, we often encounter the phenomenon of withered yellow or blackened leaves. So, is the orchid withered leaf asked by the subject sick? Is it necessary to apply medicine? In this article, I will not talk about the blackening of the leaves, but only about the withered leaves,
There are usually three cases of dead leaves of orchids. If we analyze them one by one, you will know if you are sick.
First, when the orchid goes down the mountain and goes into the pot, the orchid needs a period of time, during which the orchid root does not form a new root, and it also needs a process of adaptation to the new environment and plant materials. Langen can not absorb nutrients from the soil, but the orchid plant will not stop growing because of this reason, so it is necessary to obtain nutrients from the old seedlings, resulting in the withering and yellowing of the old seedlings. This is a normal aging seedling, not a disease. It will be better after taking the basin.
Second, the plant material or environment is too dry, resulting in the lack of moisture in the root. The instinct of plant reproduction will ensure the nutrients of the new seedlings, so the old seedlings will be supplied free of charge, which is also the reason why the orchid leaves are withered and yellow. Carefully observe whether there is a shortage of water, at this time watering should not be big, because Langen is too thirsty, can not drink too much water, it is appropriate to slow down the seedlings many times.
Third, diseases, disease symptoms caused by many bacteria will wither leaves. After excluding the above two articles, it is basically the third one. This kind of withered leaves need to be applied, mostly bactericidal drugs, and the stocking position should be moved to a cool and ventilated place. Once the dead leaves of orchids are irreversible, no matter which case, the dead leaves will be cut off at last.
