Can I use vinegar to remove black spots on orchid leaves?

1. Can I use vinegar?

Black spots on orchid leaves are a disease that can be alleviated by using vinegar. You just need to spray it on the leaves. In addition to alleviating black spots, it can also alleviate diseases such as yellowing and powdery white. It is a relatively effective method. However, it cannot cure the disease completely. Generally, black spots appear on the leaves because the roots underneath are rotten. If you want to cure it completely, you still need to take other measures.

2. Solution

1. Prune rotten roots: slowly take out the plant, trim the old roots next to it, cut off the rotten parts, and then rinse it with water.

2. Repot early: prepare a new pot, add suitable substrate into it, be sure to pay attention to drainage and ventilation, and then plant the plant in it.

3. Control light: After completion, place it in a place with good air circulation and avoid exposing it to the sun.

4. Reasonable watering: After the plant gradually adapts, it needs to be watered correctly. Do not water too much to avoid water accumulation and root rot again. If placed outside, choose a place that can be sheltered from rain for maintenance. If you accidentally get caught in the rain, you need to pour out the water in the basin in time.
