What if there are black spots on the leaves of orchids?

The black spots on the leaves of orchids show that orchids are infected with viruses, indicating that viruses invade orchids, and if flower friends do not pay attention to controlling the spread, it will endanger the growth of orchids. Black spots mostly appear in summer and autumn when it is hot, rainy, sultry and windy.

Some orchids have black spots in the center of their leaves, while others have black spots on the edges of their leaves. At first, the black spot is a small point on the tip of the needle, which will gradually expand and grow into an obvious round black spot, which will hinder the transportation of orchid nutrition. The upper part of the leaf withered slowly, and the lower part accelerated aging.

After the appearance of black spots, flower friends need to master three tips and techniques to prevent them well:

1. Spray carbendazim on orchids once or twice a year before the high temperature rainy season comes; Usually pay attention to put orchids in ventilated places, so that the air in orchids can circulate.

2. Observe the changes of orchid leaves. If there are dark spots on orchid leaves, isolate them in time and apply them with aloe juice or skin ulcer liquid.

3. Don't stop watering orchids and keep the soil dry after discovering the black spots on the leaves of orchids.
