Prepare the area where you are going to plant the nopal cactus pad. Remove all weeds and add additional potting soil, such as sandy loam, to the area.
Cut off one individual pad from an existing nopal cactus for every one that you wish to plant using a knife. Use tongs or well-padded gloves to remove the pad.
Lay the pad on a dry surface, preferably in direct sunlight, for a couple of days to allow the pad to dry out somewhat.
Place the cut pad of Nopal cactus cut-side down into the area that you previously prepped.
Water the surface of the soil just to make it wet so that the pad can settle into the soil.
Wait for roots to develop, which should occur within a few weeks.
