What to do if the leaves of white orchid turn black and fall off

Yellowing disease

If you want to prevent and control the problem of white jasmine leaves falling, you must first understand the reasons. In fact, it is not difficult to find that this situation must be caused by problems in plant management. One of the main reasons is that the leaves may be infected with yellowing disease. The symptoms of the disease are that the newly sprouted buds at the top of the branches lose their green color, and then gradually show a top-down trend, slowly extending downwards. If timely measures are not taken to control the problem, the veins of the leaves will turn yellow, burn, and eventually fall off.

In this case, you can appropriately supplement the plant with some ferrous sulfate. You can apply it to the soil, or bury a small ferrous sulfate particle in the cortex under the plant and then wrap it with plastic film. You can also dilute it with water and spray it on the diseased leaves. Repeat the operation for several cycles and it will be cured.

anthrax

The greatest harm of anthracnose is that it attacks the leaves of white orchid. In the early stage, it mainly manifests as a small faded spot on the surface of the leaf, which then gradually expands and later develops into a size that occupies half or even the entire leaf. The edges become burnt and the leaf margins become black, and then the leaves fall off more rapidly. The best way is to use the drug Anthrax Fumei, mix it with water in proportion and spray it on the affected area, which can improve this situation.
