What to do about root rot in cactus? Learn one trick to easily solve it

To solve the problem of root rot in cactus, first take it out of the pot, cut off the rotten parts and disinfect them, then place it in a ventilated place to dry, and once completely dry, insert it into the potting soil. Usually, 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. Remedial 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 place to dry. If it is not dried, it will be difficult 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. Preventive methods

1. Reduce watering

Reason: Cacti do not need too much water. If watered excessively, water will accumulate, and combined with an unventilated environment, its roots will easily rot and the whole plant may die.

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

2. Fertilize in moderation

Reason: When fertilizing a cactus, it is easy to apply too much if the amount is not well controlled, or applying unfertilized manure may also 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 concentration too high. During its growing period, fertilize once every 15 days. In winter, it is best not to fertilize, or apply only a small amount of fertilizer, so that root rot will not occur.

3. Adjust the temperature

Reason: If the winter temperature is low, the cactus will suffer frost damage, which can cause 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. The leaf surface can also be wrapped with plastic film, which can help protect against cold and keep it warm.
