Prickly pear

Sun

Full sun; choose a hot, sheltered position.

Water

Low once established. Water young plants and containers thoroughly, then let the soil dry out; keep nearly dry during cool winter weather.

Soil

Sharply drained sandy, gravelly or rocky soil. For containers, use cactus compost with added pumice or coarse grit; avoid water-retentive soil.

Height

10-16 ft (3-5 m)

Spread

6-10 ft (1.8-3 m)

Flowers

Late spring to summer; yellow to orange flowers, followed by fruit that may ripen yellow, orange, red or purple.

Foliage

Evergreen. Broad, flattened green to blue-green stem pads replace conventional leaves. Pads may bear long spines, but even nearly spineless forms have irritating, hairlike glochids.

Growth

Moderate to fast in warm conditions; slow in cool climates.

Care needed

Low

• Plant above the surrounding soil level where drainage is uncertain; do not bury the base deeply.
• Allow soil to dry between waterings and never leave containers standing in water.
• Feed container plants lightly with cactus fertiliser in spring; established plants in the ground usually need no feeding.
• Use gravel rather than moisture-holding organic mulch around the base.
• Move containers into bright, frost-free shelter before winter in cold regions.
• Handle pads with tongs and protective clothing; gloves alone may not stop the fine glochids.

Pruning. In late spring or early summer, remove damaged, crowded or overhanging pads by cutting cleanly at their joints with disinfected tools. Collect every fallen pad, as discarded pieces can root.

Spring

Check for winter rot and remove dead or softened pads once conditions are warm and dry.

Late spring

Plant or repot into sharply drained soil, and gradually acclimatise overwintered plants to direct sun.

Early summer

Thin awkward growth if necessary and take pad cuttings during dry weather.

Summer

Water containers only after the mix dries; inspect pads for cochineal and scale.

Late summer to autumn

Harvest fully coloured fruit with tongs and remove all glochids before handling or eating.

Autumn

Reduce watering and move pots under bright, frost-free cover where winters are unsuitable.

Winter

Keep sheltered plants nearly dry and provide good ventilation.

• Use as a sculptural focal point in a sunny gravel garden, with generous clearance from paths.
• Combine with agaves, yuccas and low drought-tolerant plants for contrasting leaf shapes.
• Grow in a substantial, stable container on a sunny courtyard or terrace where it can be protected in winter.
• Include in an edible dryland garden where the climate allows fruit to ripen.

Garden styles it suits: Desert modern, Architectural minimal, Mediterranean, Desert / xeriscape, Mexican hacienda and Edible landscape.

Plant it with: Agave, Yucca, Lavender, Rosemary, Santolina and Ice plant.

Wildlife: Flowers provide pollen for bees, and ripe fruit attracts birds and other animals. Dense plants can offer shelter, but escaped growth can displace native vegetation.

• Root or stem rot: improve drainage, stop watering during cool conditions and remove affected tissue; salvage healthy pads if the base is rotten.
• Cochineal insects: white, cottony patches conceal sap-feeding insects; isolate affected pots and remove small infestations with a firm water jet or an insecticidal soap labelled for cactus use.
• Scale insects: remove small colonies manually and use an appropriate labelled treatment if they persist.
• Frost damage: blackened or collapsed pads indicate injury; provide winter shelter and wait until spring to cut back to sound tissue.

Not known to be chemically toxic to people, cats, dogs or horses. Prepared young pads and ripe fruit are edible, but spines and tiny glochids on pads and fruit can cause painful skin, mouth and eye injuries; swallowed spines can cause serious internal injury. Keep away from pets, children and livestock access routes.

Where it spreads. Can escape cultivation and form dense stands in parts of Australia, South Africa and the Mediterranean region. Detached pads root readily, and animals disperse the seeds. Australian restrictions differ by state and species; Opuntia ficus-indica is exempt from some broader prickly-pear bans, but check local rules before planting or sharing cuttings.

• Engelmann's prickly pear (Opuntia engelmannii)

  Usually a lower, spreading shrub with more conspicuous clusters of long spines; Indian fig more often develops a tall, trunked framework. Variable forms can be difficult to distinguish.

• Drooping prickly pear (Opuntia monacantha)

  Usually has thinner, glossy green pads, often drooping, with one or two prominent long spines at many areoles.

• Bunny ears cactus (Opuntia microdasys)

  Has much smaller pads dotted with dense yellow or white glochid clusters and remains far smaller than mature Indian fig.

The epithet ficus-indica means 'Indian fig', referring to its figlike fruit and the historical association of the Americas with the Indies.

Propagation. Take a healthy mature pad in late spring or summer. Let the cut surface dry and callus for about one to two weeks, then insert the base shallowly into dry, gritty compost; keep warm and introduce light watering sparingly as roots develop. Do not distribute plants where local weed rules prohibit it.
