The bunny ear cactus is a favored indoor plant, appreciated for its visual appeal and minimal care requirements. Originating from northern Mexico and the deserts of Arizona, this cactus is commonly referred to by various names, such as the bunny ear cactus, angel’s wings cactus, and polka dot cactus. However, don’t let its charming names deceive youdespite its seemingly harmless appearance compared to other cacti with large, menacing spines, the bunny ear cactus is equally spiky. The white dots adorning its surface are actually glochids, clusters of tiny spines that can easily detach and embed themselves in the skin. Therefore, it’s important to handle the bunny ear cactus with caution and to always wear protective gloves.
The cactus grows at a gradual pace, often requiring as much as 20 years to fully mature. It seldom produces flowers when kept indoors.

Light
The bunny ear cactus thrives on ample bright, direct sunlight, making it essential to position it in the brightest area of your home when cultivated as a houseplant. It ideally needs six to eight hours of direct sunlight daily. For indoor growth, a south or west-facing window is the best choice, or you can utilize a grow light to enhance its light exposure. If you are growing it outdoors, make sure to avoid areas that are shaded.
Soil
Similar to many cacti, the bunny ear cactus thrives in dry, sandy soils that drain well. A typical cactus or succulent potting mix works well and can be easily sourced from most nurseries or garden centers. Alternatively, you can create your own potting mix at home by combining equal amounts of potting soil, coarse sand, and perlite.
Water
This desert plant is resilient to dry conditions and does not need regular watering to thrive. The bunny ear cactus is highly susceptible to excessive watering and can develop root rot if it receives too much moisture. It’s important to let the soil dry completely before the next watering, and if you’re unsure, it’s better to wait a little longer before watering again. Keep in mind that in desert environments, cacti can go for weeks, and in some cases, even months, without any water.
Climate and Moisture Levels
The bunny ear cactus flourishes in warm, arid environments and is sensitive to frost and high humidity levels. It performs best in temperatures exceeding 70°F and can withstand summer heat reaching up to 100°F. This cactus can be cultivated outdoors throughout the year in USDA zones 9 to 11.
Fertilizer
This cactus thrives in low-quality soils and does not need frequent fertilization. Nonetheless, it can benefit from an annual dose of cactus or succulent fertilizer in early spring, which can enhance its growth during the active growth season.
Pruning
During spring, trim away any thin or unhealthy pads. Removing the tips of the pads promotes branching and denser growth. Additionally, you can reshape an overgrown bunny ear cactus, but be careful not to cut away more than one-third of the plant in a single session.
Reproducing Bunny Ear Cactus
Similar to many other cacti, the bunny ear cactus can be readily propagated through cuttings.
- Detach a pad from the cactus and place it in a dry location for a day to allow the base of the pad to form a callous.
- Fill a container with a potting mix that allows for good drainage, preferably a mix designed for cacti. Gradually add water until the potting medium is thoroughly saturated and excess water begins to flow from the drainage holes.
- Place the pad with the cut side facing down into the soil, pushing it down about an inch, and lightly compact the soil around it. As an alternative, you can position the pad flat on the soil surface, which is more effective for larger pads.
- Position the pot in an area where it can soak up a few hours of direct sunlight daily.
- Hold off on watering until the roots are established. Be cautious with the amount of water, as excessive watering can cause rot. After several weeks, you should start to see root growth.
Transplanting and Replanting Bunny Ear Cactus
The bunny ears cactus needs to be repotted every two to three years. When repotting, it’s important to wear thick gardening gloves to shield your hands from its sharp spines. You can also use tongs to handle the cactus without direct contact.
Utilize gloves or tongs to securely grip the cactus, then carefully maneuver the root ball out of the previous pot, aiming to dislodge as much of the old soil from the roots as possible. Next, place the cactus into the new pot, surrounding the roots with fresh soil and pressing it down firmly.
Overwintering
Cacti cannot withstand frost. In regions below USDA zone 9, it’s best to cultivate them in pots and move them indoors for the winter. Place them in a spot that receives some sunlight and maintains a temperature between 50 and 65 degrees Fahrenheit. During the winter, water them only minimally.
Frequent Insects and Plant Illnesses
The bunny ear cactus may sometimes encounter typical pests like mealybugs or scale, but it generally remains quite resilient against infestations. These sap-feeding pests can be managed effectively by applying rubbing alcohol to the infested spots using a Q-tip or cotton swab on a regular basis.
One of the most prevalent issues to be aware of is root rot, which occurs due to excessive watering or high moisture levels. A clear indication of root rot is the presence of brown, mushy stems and roots. Regrettably, by the time root rot is detected, it is often too late to take effective action. It is advisable to quickly remove the healthy pads and propagate them.
Is it against the law to possess bunny ear cactus?
In Australia, the bunny ear cactus is designated as a restricted invasive species according to the Biosecurity Act, which prohibits its sale, possession, or release into the wild. Conversely, there are no such regulations in the United States.
What could be causing my bunny ear cactus to sag?
Wilting may indicate either excessive or insufficient watering. Check your watering schedule to determine if adjusting it resolves the issue.
Do bunny ear cacti produce flowers?
When kept as a houseplant, it seldom produces flowers. However, in outdoor settings, it can bloom under optimal growth conditions that replicate the sunlit, dry desert environment, characterized by warm days and cooler nights.
