How to care for Bunny Ears Cactus

Opuntia microdasys · Cactaceae

cactuseasy to growpet-safe

Paired oval pads dotted with polka-dot tufts give this Mexican prickly pear its adorable rabbit silhouette — but those fuzzy dots are glochids, hundreds of hair-fine barbed bristles that detach into skin at the lightest touch. Look, never pet. Beyond that one rule it is a classic easy cactus: sun, grit, and near-neglect. Water roughly every 16 days while it's growing (about every 40 in winter), give it direct sun, kept above 45°F (7°C) — dry air is fine for it.

Care at a glance

Water: every ~16d growing · ~40d dormant
Light: Direct sun
Humidity: dry air is fine — no extra humidity needed
Keep above: 45°F (7°C)
Feed: every ~60d in season
Repot: every ~3 years

Water deeply once the soil has been fully dry for several days, and keep it almost completely dry over winter.

Direct sun for most of the day keeps pads thick and well-spotted; south-facing exposure is best.

Dilute cactus fertilizer once or twice in spring and summer.

Mistakes that kill this plant

  • Winter watering while the plant is cold and resting.
  • Placing it within reach of pets, children, or passing sleeves.
  • A shady spot that produces weak, etiolated pads prone to flopping and rot.

Seasonal tips

  • Give it a cold, dry, bright winter rest to encourage compact spring pads and possible flowers.
  • Handle only with thick folded newspaper or leather gloves — never fabric gloves, which glochids penetrate.
  • Remove any embedded glochids from skin with tape or tweezers promptly.
