Taking Care Of Opuntia Microdasys Monstrose “Crazy Bunny Ears”

Ideal conditions

Having high light demands, Opuntia Microdasys Monstrose “Crazy Bunny Ears” will do best outdoors. The Crazy Bunny Ears cactus does well when provided with at least 6 hours of full sun per day, and while this isn’t impossible to ensure for indoor plants, it’s much easier to achieve when keeping this cactus outdoors.


Opuntia Microdasys Monstrose “Crazy Bunny Ears” has typical water needs for a succulent. It’s drought-resistant and doesn’t need much water, so you should only water it when its soil is dry to the touch. Too frequent watering can lead to waterlogging and root loss.

The Crazy Bunny Ears cactus is dormant in winter and should thus be kept dry. You can do this because this cactus’ water needs in winter are very low.

Also, keep in mind that cacti are much more sensitive to overwatering in winter than in summer.

Where to plant

To prevent water from accumulating around the roots of this cactus, plant it in a fast-draining cactus potting mix. For extra drainage, you may add mineral grit like perlite or coarse sand. There aren’t strict guidelines on how much mineral grit to add, but a 1:1 ratio between the grit and potting mix should be adequate.

Opuntia Microdasys Monstrose “Crazy Bunny Ears” isn’t a big cactus and can be easily kept in a pot. When choosing a pot, get one with large drainage holes at the bottom.

If you want to see the Crazy Bunny Ears cactus thrive and want it to obtain its distinctive structure, then you should keep the cactus outdoors. Roughly 6 hours of full sunlight are a must for this cactus.

Indoor growing is also possible, but only if you can provide the Crazy Bunny Ears cactus with adequate sunlight. If sunlight is lacking, then you may compensate for it with grow lights, but keep in mind that natural light is preferable.

In winter, be sure to move this cactus indoors – it’s not frost-hardy and will not survive long-term exposure to low temperatures. But you won’t need to do this if winters are warm in your area.

General care information

Occasionally fertilize your Opuntia Microdasys Monstrose “Crazy Bunny Ears” cactus to ensure consistent growth. Opuntia Microdasys cacti tend to be slow growers, so every bit of growing boost you can get is beneficial.

Fertilization should be done throughout spring and summer. Typically, cacti fertilizers diluted to half strength are given to the cactus once every 4-8 weeks, though this may depend on your fertilizer.

Repotting should also be done sometimes. A small pot will restrict your Crazy Bunny Ears cactus and prevent it from growing further. Ideally, repot your cactus every spring so that you can inspect its roots and treat them if necessary. If you can’t do this, then repot the cactus once it outgrows its pot.
