Grated Moon Cactus Stock
The top of my moon cactus began to shrivel and leak, so I removed it from the rootstock. Instead of grafting something onto it, is there anything else I can do with the stock? Also, what type of soil is best for these types of cacti?
The moon cactus needs to be grafted onto another rootstock because it lacks the ability to photosynthesize - meaning it can't make its own food.
