There are many reasons for the shrinkage of the folds at the base of the cactus. If it is overwatered, you need to dig out the cactus, check the root system, remove any rot in time, dry the wound and replant it. If the temperature is too low, you need to find ways to increase the curing temperature, such as placing a heated room or covering it with a plastic bag. If it is exposed to the scorching sun, it needs to be properly shaded in summer or moved to the east balcony for maintenance.

1. Overwatering

1. Overwatering

Cause: The cactus is a succulent plant and is particularly drought-resistant. If water is overwatered and the soil accumulates water, it will easily lead to root rot, which is manifested at the bottom of the cactus. The folds shrink and, in severe cases, cause the cactus sphere to rot.

Solution: If the pot soil feels damp, dig out the cactus and check the root system. If there are any rotten parts, remove them in time. Apply some carbendazim to the wound and let it dry before replanting it in moist soil. The flowerpots for planting should not be too large, and use breathable earthenware pots.

2. The temperature is too low

Reason: Cactus likes warmth and is afraid of cold. In winter, it is best to ensure that the maintenance temperature is above 10℃. If it is below 10℃, watering should be reduced. If the temperature is below 0°C, cactus is prone to frostbite, which is manifested by yellow spots on the sphere and wrinkles and shrinkage at the bottom of the plant.

Solution: Avoid applying nitrogen fertilizer in late autumn and apply more phosphorus and potash fertilizer to improve the frost resistance of the cactus; place the cactus in a heating room in winter, but keep it away from heating and floor heat; find a plastic bag in winter Cover the cactus and open the bag to ventilate during the day.

3. Sun exposure

Reasons : Although the cactus is a succulent plant that loves the sun, it still needs to be properly shielded from the scorching sun in summer. Long-term exposure to the sun will cause rapid loss of soil moisture, causing the bottom of the cactus to wrinkle and shrink. Sudden exposure to the sun can easily burn the ball of the plant.

Solution: The main thing to prevent is summer sun exposure. You can set up a sunshade net above the plants to block part of the light; or move the cactus to an east-facing balcony to only get the relatively soft light in the morning.
