Some Lanyou have a headache on the tip of the coke, and the causes are very complicated, which may be caused by too dry, too wet or fertilized, may also be bruised and infected, and root rot may occur. Once the focal point occurs, it is indelible. The common method is to cut the leaves (until the green part), pick out, pierce and other methods to control. Interested orchid friends might as well try the half-fold method, that is, fold in half at the green edge of the focal point to block the water supply and curb the expansion of the focal tip. When folding in half, the sound of breaking can sometimes be heard, which indicates that the focal tip is caused by overdrying. If there is no sound, there is moisture coming out of the fold, it may be too wet or fat injury (the fat wound is cooked at first, then the infection spreads). Through the half-fold examination, the problem can be found, so that the right medicine can be treated. This is much more fun than just cutting it off.

In addition, the part of the focal point is treated by the folding method, and there is another judgment function: to observe the development of the focal tip and disease spot in the upper and lower position of the fold. In general, it can be found in 3-5 days: the upper part of the broken line is dried, from dark brown to yellowish brown, and the disease focus no longer appears in the lower part of the broken line, which shows that the focal tip is caused by infection of fungi after physical injury, and the development of the focal tip can be controlled by blocking moisture. At this point, cut off the whitening part. If the focus continues to occur in the lower part of the broken line, and after folding down again, dark-brown disease spots still appear in the lower part of the fold, at this time, it should be suspected that the root has pathogens invaded and transported to the folded line wound, showing the expansion of the disease. It is suggested that in this case, the root should be checked until the pot is turned over and replanted!

Prevent coke tip, mainly control the dry humidity of plant material, plant formula should pay attention to permeability. Keep in mind that fertilization is too thick, at least 1/1000 or more, or even lighter. At the same time, maintain orchid ventilation and a certain degree of environmental humidity. If focal points and disease spots occur, the above methods can be used to deal with them. You can try!
