DC,
I am also, disabled, having my left leg amputated. I didn't know about your mum so I apologize if I had given any offense. I only mention the cardboard method as a no-dig,no till method of gardening. Personally, I eat the purslane. Purslane contains a high dose of Vitamin C and trace minerals; it also has a nice tart taste that goes nicely in a fresh salad or as a side for fish.
