What causes orchids to have empty roots? How to save orchids with empty roots

1. Not watering thoroughly

1. Reason: When watering orchids, it is most taboo to water halfway and not fully water the planting material. This will cause the top half of the planting material to be moist and the bottom half to be dry. In this way, the roots under the planting material will become dehydrated because they cannot absorb water normally, resulting in the problem of empty roots.

2. Solution: At this time, the watering method should be improved to ensure that the planting material is completely wet each time it is watered. Specifically, every time you water, you should wait until you see water flowing out of the drainage hole at the bottom of the flower pot before stopping watering.

2. Hardening of the planting material

1. Reason: If the planting material used to maintain orchids is of poor quality or is used for too long, hardening may occur inside the orchid. The air permeability of compacted planting materials will be greatly reduced, and the roots of the plants will have difficulty breathing, resulting in root rot.

2. Treatment method: At this time, you need to replace the plant with a more breathable planting material. When changing the soil, it is best to add large, medium and small particles of planting material into the flowerpot in turn. This will allow the planting material at the bottom to maintain maximum air permeability to avoid the problem of empty roots in the plant again.

3. Planting material is not moisturizing enough

1. Reason: If the orchid planting material has poor moisture retention ability and dries up quickly after each watering, the plant will be in a dry environment for a long time and unable to absorb water normally. In this way, it will also have the problem of empty roots.

2. Treatment method: At this time, it is also necessary to replace the planting material for the plant. The new planting material should be prepared according to the variety of orchids being grown to ensure that it has sufficient air permeability and moisture retention to meet the growth needs of the plants.
