How to remedy cactus root rot

1. Remedies

Take the cactus out of the pot and cut off the rotten parts with sterilized scissors. If conditions permit, it is best to disinfect it. Then place it in a ventilated place to dry. If it is not dried, it will be difficult for it to survive. After the wound is dry, insert it into the potting soil. Don't insert it too deep to avoid rot. It is best not to water it before it grows roots again.

2. Prevention Methods

1. Reduce watering

Reason: Cactus does not need too much water. If it is watered too much, water will accumulate. Coupled with an unventilated environment, its roots will easily rot and cause the death of the entire plant.

Solution: Try to place it in a ventilated environment and wait until the soil is dry before watering. Water it in moderation for daily maintenance and do not water it too frequently.

2. Apply fertilizer appropriately

Reason: If the amount of fertilizer applied to the cactus is not well controlled, it is easy to apply excessive fertilizer or apply uncomposted fertilizer, which may cause root rot.

Solution: Apply fertilizer at the right time and in the right amount. Do not apply too much fertilizer or too high a concentration. It is enough to apply fertilizer once every 15 days during its growth period. It is best not to apply fertilizer in winter, or apply a small amount of fertilizer, so that the roots will not rot.

3. Adjust the temperature

Reason: If the temperature is low in winter, the cactus will be frozen, causing root rot.

Solution: Adjust the temperature appropriately. It is best to control the temperature above 5°C in winter. It is best to allow it to receive sufficient light during the day. The leaves can also be wrapped with a film to keep out the cold and keep warm.
