Bunny Ears Cactus Opuntia microdasys

Reviewed June 2026 · how we check this

A charming little prickly pear named for the way its flat, oval pads sprout in pairs like a rabbit's ears. Instead of long spines it wears neat polka dots of tiny barbed glochids, making it a slow, easygoing desert succulent that's irresistible to look at but best admired hands-off.

Light

Bunny Ears Cactus is a true sun lover and wants the brightest spot in the house — a south or west window with several hours of direct light keeps the pads plump, upright, and densely freckled with their signature glochid dots. Starved of light, the pads grow pale, thin, and stretched, and new growth points awkwardly toward the glass instead of forming the tidy paired 'ears.' Indoors through dim winters it usually benefits from a grow light. Outdoors it relishes full desert sun, but a plant moved from indoors to a blazing patio should be acclimated over a couple of weeks, or the broad pads can sunburn into pale, scarred patches.

Watering

Soak the soil thoroughly, then let it dry out completely before watering again — roughly every 2–4 weeks in warm growing weather and far less in winter, when monthly or even less is plenty. Like all prickly pears, Bunny Ears stores water in its fleshy pads and is built for long droughts, so it always prefers too dry over too wet. Overwatering is the number-one killer: soggy soil rots the shallow roots and softens the base of the pads. Pour water at the soil line, not over the pads, and when in doubt, wait another week. A slightly wrinkled, deflated pad means it's genuinely thirsty.

Soil & potting

Sharp drainage is essential. Use a gritty cactus or succulent mix, or cut ordinary potting soil heavily with coarse sand, pumice, or perlite until water runs straight through. Bunny Ears has a shallow, spreading root system, so a wide, shallow pot suits it better than a tall, deep one, and unglazed terracotta helps by wicking moisture from the mix. Always choose a container with generous drainage holes. Repot only every couple of years, in spring — and wrap the pads in folded newspaper or use thick leather gloves to handle them, since the glochids detach at the lightest touch.

Humidity & temperature

This is a desert plant that thrives in dry air and warmth, and high humidity does it no favors — damp, stagnant conditions invite rot and fungal spotting on the pads. Keep it comfortably warm, ideally between 50 and 95°F, with bright airflow. It's hardy outdoors only in Zones 9–11; below about 50°F growth stalls, and a hard frost will turn the water-filled pads to mush. In cold climates grow it in a pot and bring it indoors before the first frost. A cool, dry, bright winter rest actually encourages it to bloom the following season.

Fertilizing

Bunny Ears is adapted to lean desert soils and needs very little feeding. During spring and summer growth, a dilute cactus or succulent fertilizer at half strength, applied once a month or even less, is ample — and many plants do fine with nothing at all. A diluted high-potassium or 'bloom' formula in spring can nudge a mature, well-rested plant toward its cheerful yellow flowers. Never feed in fall or winter while growth has stalled. Over-feeding pushes soft, oversized, easily damaged pads and can leave a crusty mineral build-up on the soil surface.

Pruning & maintenance

Pruning is rarely needed, but you can remove a damaged or shrivelled pad, or take off a few pads to reshape a lopsided plant, by snapping or cutting cleanly at the narrow joint where pad meets pad. Always wear thick gloves and grip the pad with tongs or folded newspaper — the barbed glochids lodge painfully in skin and are maddening to remove. Pruning in spring lets cuts callus quickly in the warmth, and every removed pad is a ready-made cutting. Sweep up any shed glochids so curious pets and bare feet don't find them.

Propagation

Bunny Ears practically begs to be propagated, since each pad is a cutting waiting to happen. Wearing gloves, snap or cut a healthy pad off at its joint, then set it somewhere dry and shaded for several days to a week until the cut surface forms a firm callus — skipping this step invites rot. Press the calloused end about an inch into gritty, barely moist cactus mix, prop it upright if needed, and wait. Withhold water for the first week, then water sparingly. Roots and new growth usually appear within a few weeks. It's reliable, fast, and true to the parent.

Through the year

Spring

Active growth resumes and new pads form — return to soak-and-dry watering, repot if crowded, and feed lightly once to encourage spring blooms.

Summer

Peak growth under full sun. Water only when the soil dries completely, and watch for sunburn on pads moved suddenly into intense light.

Fall

Growth slows toward dormancy — taper watering sharply, stop feeding, and bring potted plants indoors before the first frost.

Winter

Largely dormant. Give it a cool, dry, bright rest, water rarely if at all, and keep the pads out of frost and damp air.
