Taking Care Of Opuntia Microdasys “Bunny Ears”

Ideal conditions

Opuntia Microdasys “Bunny Ears” is best to grow outdoors for two reasons – it thrives under partial to full sunlight, and it will easily grow to its natural height of 3-4 feet outdoors where there is enough space for it.

Indoor keeping is also possible, but when potted, the Bunny Ears cactus will have a much harder time getting big, not to mention that sunlight isn’t as abundant indoors.


Opuntia Microdasys “Bunny Ears” is very sensitive to overwatering and should only be watered when its soil is dry to the touch. Excessive amounts of water will very likely lead to root rot.

In winter, suspend watering to allow the Bunny Ears cactus to enjoy its dormant period. When dormant, cacti require little to no water to survive, and overwatering is much more likely to cause root rot in winter than in summer.

Where to plant

To ensure adequate water drainage, plant your Opuntia Microdasys “Bunny Ears” cactus in a fast-draining cactus potting mix. Consider adding coarse sand or perlite in a 1:1 ratio to the potting mix to further improve drainage.

If you are intending to keep this plant potted, then choose a pot that has large drainage holes at the bottom.

If you want to see your Opuntia Microdasys “Bunny Ears” in its full beauty, then keep the cactus outdoors, preferably in the ground rather than in a pot. It’s much easier to get this cactus to its full size when it is in the ground not restricted by the pot.

With that said, ground growing is reasonable only if winter months are warmer in your area. Otherwise, you will have to repot the cactus to bring it inside, which can be tricky.

Another thing to keep in mind is that Opuntia Microdasys “Bunny Ears” cacti easily spread in the ground and can easily take over your landscape. If this is undesirable, keep this cactus in a pot.

Indoor growing is also possible with the Bunny Ears cactus, but keep in mind that this cactus prefers full sunlight and will not grow adequately in a shaded location. Only keep this plant indoors if you have a window sill that is lit directly by the sun. 

General care information

Opuntia Microdasys “Bunny Ears” grow fairly slowly, and it will take years before it reaches a few feet of height. In the meantime, you should fertilize the soil with a cactus fertilizer diluted to half strength to ensure consistent growth. Fertilize the cactus throughout spring or summer once every 4-8 weeks.

Since this cactus is a slow grower, you probably won’t have to repot it into a bigger pot every year. However, annual repotting can also be very beneficial – it allows you to inspect the cactus’ roots and introduce the plant to fresh soil, possibly boosting its growth.
