The Donkey Ear Plant (Kalanchoe gastonis-bonnieri or Kalanchoe daigremontiana) is a distinctive succulent known for its unique, elongated leaves resembling a donkey’s ear. Its striking foliage, often mottled with brown spots, makes it an appealing choice for indoor gardeners. This plant is also relatively easy to care for, making it suitable for various experience levels.
Donkey Ear Plant Care Essentials
Donkey Ear Plants thrive in bright, indirect sunlight, which helps maintain vibrant foliage and compact growth. An ideal spot is near a south or west-facing window, providing ample light without harsh afternoon sun.
Excess direct sun can scorch leaves, causing brown or crispy spots. Insufficient light leads to leggy growth, where stems stretch excessively and the plant loses its upright form. Rotate the plant periodically for even light exposure.
Watering is crucial for Donkey Ear Plants due to their succulent nature. They store water in their thick leaves, making them prone to root rot from overwatering. Allow the soil to dry out completely between waterings.
When watering, thoroughly drench the soil until water drains from the pot’s bottom, then discard any excess. Water more frequently during spring and summer’s active growing season, and significantly less in fall and winter as growth slows.
A well-draining soil mix is essential for Donkey Ear Plants to prevent waterlogging. A specialized succulent or cactus potting mix, containing perlite or sand, is recommended to enhance drainage.
Good drainage aerates the root zone, preventing fungal diseases and maintaining root health. Repotting every few years may be necessary to refresh the soil and accommodate growth.
Donkey Ear Plants prefer average room temperatures, from 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). They are not frost-tolerant and need protection from temperatures below 50 degrees Fahrenheit (10 degrees Celsius). Average household humidity is sufficient, as they do not require high humidity.
Fertilizing can support healthy growth, but it is not a frequent requirement. During the spring and summer growing season, apply a balanced liquid fertilizer, diluted to half strength, once a month. Over-fertilization can harm the plant, so use moderation.
Propagating Donkey Ear Plants
Donkey Ear Plants propagate uniquely by producing small plantlets along their leaf margins. These miniature plantlets, complete with tiny roots and leaves, are clones of the parent plant, making propagation straightforward.
To propagate, gently remove plantlets when they are about half an inch to an inch in size. Place them directly onto the surface of a well-draining succulent or cactus potting mix.
Keep the soil lightly moist, but not soggy, during the initial rooting phase. Once established, care for the new plants as you would a mature Donkey Ear Plant.
Addressing Common Donkey Ear Plant Issues
Overwatering is a common issue, often leading to mushy stems or yellowing leaves. If these symptoms appear, reduce watering frequency and ensure the plant is in well-draining soil to prevent root rot.
Conversely, underwatering manifests as wilting or crispy leaves. In such cases, provide a thorough watering, allowing excess water to drain, and adjust your watering schedule to be more consistent.
Spider mites or mealybugs can affect Donkey Ear Plants, appearing as small white cottony masses or fine webbing on the leaves. Manage these pests by gently wiping them off with a cotton swab dipped in rubbing alcohol or by using an insecticidal soap formulated for houseplants.
Safety Considerations for Donkey Ear Plants
Donkey Ear Plants are toxic if ingested, especially for pets and young children. They contain compounds that can cause gastrointestinal upset. Keep these plants out of reach of curious pets and small children. If ingestion occurs, seek advice from a veterinarian or medical professional.
