Hey Null, I actually don't know if I want any of those pads anymore, Ive experiment with some other opuntias and they all seem to rot on me
In ground or container? I had Torrance PCH#1 fruit in the ground in PSL, sugar sand type soil. It did get flooded a few times (I was not pleased with its progress, because it was getting heavy competition from st augustine grass and weeds. I moved it into a container, which I would suggest as the optimal method to grow for fruit (unless you have a gravel/rock garden area where the plant does not have competition with weeds.
The time that the pad is most susceptible to rot is when there is an open wound or the pad was recently disconnected. I use powdered sulfur on the wound to dry it out and prevent rot issues once the pad is disconnected. The pads native habitat is sandy soil on the side of a ridge very close to the coast, cool coastal marine layer days and higher humidity are common in this area. I don't see it having many issues with humidity as long as its in full sun with good drainage.
For inground planting, I recommend grafting it to native Opuntia sp. rootstock or any of the Opuntia sp. native to hot humid climates. This should show better inground performance with waterlogged conditions and nematode resistance. Not all Opuntia sp. are created equal when it comes to tolerance of humidity and water, Opuntia sp. PARL 342 is more adapted to desert conditions it seems and has horrible rot resistance. I have other PARLs in Florida that seem to be doing good though.
