How to save the cactus if it is rotten, and how to remedy the cactus when it is rotten

Rotten and dead, there is no way.

Water less with a nutrient solution.

Root excision: Rotten roots are removed along with a small amount of healthy tissue. Use quicklime:

Cut off the rotten parts and sprinkle quicklime on the rotten roots. Disinfection treatment: remove the rotten parts as much as possible, and rinse repeatedly with potassium permanganate solution.

Precautions: Fungicide should be mixed into the potting soil where the cactus is planted for disinfection.

1. Cut off the root system

If the cactus ball is only scattered like a star, the rotten roots can be cut off along with a small amount of healthy tissue, and then the wound can be coated with plant ash to prevent infection and disease, speed up the wound healing, and finally place it in a dry and ventilated place to dry.

2. Use quicklime

If the rotten part of the cactus ball is in the shape of a nest, you need to cut off the rotten flesh, sprinkle quicklime on the rotten roots, clean it while sprinkling, and after two or three times, put the plant in a ventilated place to dry, if it is in summer, you can use the soil sand heated in the sun to sprinkle the rotten roots.

3. Disinfection treatment

If the cactus is rotten in many places, but the middle is healthy, you can remove the rotten parts as much as possible, rinse them repeatedly with potassium permanganate solution, or soak the plants with 500 times of 50% compound thiophanate-methyl wettable powder, and finally put them in a ventilated place to dry and replant.

4. Precautions

When the cactus is replanted after the rotten parts are treated, the new potting soil should be mixed with 95% dicorosone soluble powder and other fungicides for disinfection, and after the planting is completed, it is placed in an environment with air humidity of more than 60% without watering.

Cactus balls can survive rotting, so they should be depotted in time, and the rotten parts and roots should be pruned off with sterilized scissors. The wound is then disinfected with carbendazim solution and placed in a cool place to dry. It is then repotted and planted in new soil, carefully maintained and waiting for it to recover.

When it is found that the cactus ball is rotten, it can be saved. First of all, you need to remove the cactus from the potting soil, taking care not to hurt the root system. Then smooth out the roots one by one, and use sterilized scissors to prune off the rotten parts and roots.

After pruning, disinfect the wound with carbendazim solution and place it in a cool and ventilated place to dry. Finally, when repotting, the potting soil can be fully disinfected and sterilized, which can effectively avoid the recurrence of decay.

After the cactus is replanted, it is necessary to maintain and manage the cactus in order to avoid root rot again. Do not water too much in the early stage to avoid the potting soil being too wet. If the potting soil is relatively dry, you can water a little water to keep the potting soil slightly moist.

Maintain adequate sunlight every day to help cactus grow healthily and vigorously. In summer, it is necessary to pay attention to proper shade and prohibit long-term exposure. In winter, when the temperature is cold, you can move it indoors to a warmer and sunny place.
