History

A brief account

Cultivated by the Aztecs as nopalli, its pads and tunas appear on the Mexican flag. Carried by Spanish galleons to the Mediterranean, North Africa and Australia, where it became both staple food and notorious invader.

How to care for

Prickly Pear (Opuntia ficus-indica) grows best when its natural cycle of strong light, freely draining soil and measured watering is respected. Give it full sun year-round. will etiolate badly without it. Water it according to its seasonal needs: sparingly during growth; keep dry through winter rest. Plant it in sandy, fast-draining mineral mix with a little compost. A container with an unobstructed drainage hole is essential, because moisture lingering around cactus roots can quickly lead to rot. Keep its temperature needs in mind: -5 to 40°c. surprisingly cold-hardy when dry. During active growth, check the compost before watering rather than following a rigid calendar, since heat, light and pot size all change how quickly it dries. Reduce watering during cool or dormant periods, keep the plant well ventilated, and wait until the growing medium is dry before watering again.

How to propagate

Sever a pad, callous for a week, then set upright in dry sand. Take material from healthy growth with a clean blade or tongs, then leave the cut surface in a dry, shaded place until it forms a firm callus. Set it into a dry, gritty medium and introduce water sparingly only after roots begin to develop. Young cacti are especially vulnerable to excess moisture. Use a small pot with excellent drainage, provide bright filtered light while roots establish, and move the new plant gradually into the light, temperature and watering conditions preferred by a mature Prickly Pear.
