Care at a glance

Light

Full direct sun. Generous daily direct sun prevents weak elongation and keeps pads nicely rounded.

Watering

Water sparingly; soak the gritty mineral mix only when completely dry. Keep virtually dry throughout winter.

Conditions vary with pot, season and location. Always check the mix and your plant's response.

How to identify it

Popular branching cactus forming pairs of paddle pads dotted with neat polka-dot clusters of golden-yellow glochids.

Environment and placement

Warm, arid conditions (14-30 °C / 57-86 °F). Well-adapted to low indoor humidity and bright sunny windowsills.

Potting mix and feeding

Prioritise a very free-draining mix and a pot with holes. Heavy mix that remains wet for weeks raises root risk.

Feed sparingly during active growth if needed; do not fertilise a plant weakened by overwatering.

Problems to check

Etiolation (thin, elongated pads) in weak light; fine barbed glochids irritate skin upon contact.

Common question

How do you safely handle bunny ears cactus?

Use tongs or folded newspaper collars rather than garden gloves, as the micro-barbed glochids easily pierce fabric.
