1, drought and water shortage. Crab claw orchid is drought-tolerant, but if the soil is dry for a long time, the leaves of the plant will become soft and thin. Move the potted plants to a cool and ventilated place, water the plants once in time, and then water them in time when the soil in the pot is nearly dry, so that the leaves of the crab claw orchid can stand upright after a period of time.

2. The water is rotten. Crab claw orchid is drought-tolerant and afraid of water accumulation. Usually, watering should follow the principle of "dry and thorough watering". If the soil is watered too many times, the root system of the crab claw orchid is easy to rot and lose its water absorption function, resulting in the softening and thinning of the leaves of the plant. It is necessary to take the plants out of the flowerpot, check the roots, cut off the rotten roots and replant them.

3. Lack of nutrition. Crab claw orchid needs to consume a lot of nutrients every time it fails to bloom. At this time, if the nutrients in the soil are insufficient, the crab claw orchid will become soft and thin because of the lack of nutrients. Therefore, after each flower failure, it is necessary to replenish fertilizer and water in time to promote plant regeneration, rejuvenation, rapid growth and re-flowering.

4. Sudden exposure. The light is too strong in summer, so remember to put the crab claw orchid in a relatively cool place. If the plants are suddenly exposed to the sun, the leaves of the crab claw orchid will become soft and thin, so shade them in time and keep astigmatism in summer.
