Then put it in an environment of about 20℃, maintain it for a period of time, and wait for it to recover. 2. Flower fertilizer burns1.

Treatment method: Use a wet wipe to repeatedly wipe the leaves with black spots on the plant to wipe off the fertilizer on them, and then maintain it for a period of time. If there are leaves with a lot of black spots, it is recommended to cut them off directly. 3. Spraying to remove bacteria1.
