Known Hazards
The plant has numerous minutely barbed glochids - these are barbed spines that are usually small to minute and are very sharp and brittle. The glochids are very easily dislodged when the plant is touched and can penetrate the skin where, because of their barbs, they become stuck and are very difficult to see and remove. They can cause considerable irritation and discomfort[

Opuntia species can contain quite high levels of oxalic acid, especially in older parts of the plant. Perfectly alright in small quantities, foods containing oxalic acid should not be eaten in large amounts since it can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[

Propagation
Seed - sow early spring in a very well-drained compost in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first two winters. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Give the plants some protection from winter wet. Make sure you have some reserve plants in case those outdoors do not overwinter.
Cuttings of leaf pads at any time in the growing season. Remove a pad from the plant and then leave it in a dry sunny place for a couple of days to ensure that the base is thoroughly dry and has begun to callous. Pot up into a sandy compost. Very easy, rooting quickly.
