The rotten cactus can also take root by hydroponic culture. first, deal with the rotten root, dig out the sphere, cut off all the rotten part, then smear a little carbendazim and put it in a ventilated place for at least three or five days until the wound is completely dry. The more water it lacks, the faster it will take root.

Choose a water culture bottle of the right size, add water and nutrient solution, fix the cactus at the mouth of the bottle or set the planting basket, the nutrient solution should not touch the sphere, about one or two centimeters away from the sphere, so as to avoid cactus decay. After that, it is best to cover the transparent bottle when it has not taken root, and only the sphere can see the light.
