Does anyone have any advice on growing Opuntia lasiacanta? I picked up 3 pads from a farmers market. Just love cactus and wanted to see if the pads would root. I took them home, placed them in a pot with dry soil to see if they would root. One turned black in just 2 days so I threw it out. A week later, the other had large black spots so I pulled it out of the pot to find several roots! The remaining one is green and firm, I'm sure it has even more roots and will live. When do I water for the first time, what other needs will this Opuntia lasiacanta need as it turns from a food product into a wonderful plant in my collection? By the way, the temps here have been pushing 100 F for the last several days..but VERY humid! Several thunder stoems but the plants are under my awning and gets no direct rain.
