What causes tip burn in orchid seedlings? A principle-based analysis with prevention first

Let's talk about the tip burn problem in orchid seedlings from the principle level! Prevention first! You all know the principle that the taller the tree, the deeper the roots! Deep roots make lush leaves. Orchids are no exception. The tip burn problem is not only in Lianban orchids; all orchids in the Orchidaceae family have this problem! The causes are many-sided. It can be said that too dry will cause tip burn, too wet will cause tip burn, brown spot fungus infection will cause tip burn, too much sun will cause tip burn, stuffy and unventilated conditions will cause tip burn, overly concentrated fertilizer will cause tip burn, and compacted potting medium will cause tip burn even more. So when growing orchids, you must grow the orchid roots well. According to the introduction by the elderly Zhu Shuiting, second son of the Orchid King Zhu Zhangfu of Zhuji, every orchid leaf on the orchid seedlings he grows has no tip burn, and he took out a pot of orchids to show me, with neat white roots, not one damaged, and crystal heads transparent and shiny. It was he who told me that if the root tip rots, the tip will surely burn. The principles of orchid growth also tell us that the root tip is the vanguard of the transport team. If the vanguard is blocked, the nutrients transported are reduced. Orchid leaves function according to the factors arranged within the plant body. The root tip is like the leaf tip. Understand now! With the tip burn caused by all the above reasons, what you see is the phenomenon, but fundamentally the root tip has already been damaged to a greater or lesser extent. The facts are indeed so. As long as 3 orchid leaves have tip burn, I will deal with the orchid pot. If 3 orchid leaves are cut off, I will repot and deal with the roots. Except for professional orchid farms, tip burn is unavoidable in home orchid growing. The key is to observe frequently, identify the cause clearly, treat the root cause, and handle it promptly. For a small amount of tip burn, use a pin to pry it open, and try not to cut, as keeping it as it is is better, because orchid roots can regenerate, but orchid leaves cannot regenerate. A single orchid leaf only grows once in its lifetime. Take good care of orchid leaves as you would care for a beauty's face. ! Please excuse the comparison!
