To solve the problem of root rot in a cactus, first take it out of the pot, cut off the rotten parts and disinfect them, then place it in a ventilated spot to dry. Once completely dry, insert it into the potting soil. In normal care, control the amount of watering well, do not let water accumulate, and do not fertilize too much or too frequently, so as to avoid root rot.

I. Rescue Methods

Take the cactus out of the pot, use sterilized scissors to cut off the rotten parts, and if possible, disinfect them. Then place it in a ventilated spot to dry; if it is not dried, it will be difficult for it to survive. After the wound is completely dry, insert it into the potting soil. Do not insert it too deep, as this may cause rot. It is best not to water it before it grows new roots.

II. Prevention Methods

1. Reduce watering

Cause: Cacti do not need too much water. If you water too much in normal care, water will accumulate, and combined with a poorly ventilated environment, its roots can easily rot, which can also cause the whole plant to die.

Solution: Try to place it in a ventilated environment, and water only after the soil has dried. In daily care, water in appropriate amounts and do not water too frequently.

2. Fertilize in appropriate amounts

Cause: When fertilizing a cactus, it is easy to apply too much if the amount is not controlled well, or to apply unrotted fertilizer; either can cause root rot.

Solution: Fertilize at the right time and in the right amount. Do not apply too much fertilizer, and do not make the fertilizer concentration too high. During its growing period, fertilize once every 15 days. In winter, it is best not to fertilize, or to apply only a small amount of fertilizer. In this way, there will be no root rot.

3. Adjust the temperature

Cause: If the temperature in winter is relatively low, it will freeze and damage the cactus, thereby causing root rot.

Solution: Adjust the temperature appropriately. In winter, it is best to keep the temperature above 5°C. During the day, it is best to let it receive sufficient light. You can also wrap the leaves with plastic film, which can help protect against the cold and keep it warm.
