Kalanchoe beauverdii is a distinctive succulent known for its tall, climbing growth habit. Native to the dry shrubland forests of southern and southwestern Madagascar, this plant features slender stems that can twine and clamber, often showcasing green leaves streaked with purple and sometimes a waxy coating. During winter and spring, Kalanchoe beauverdii produces bell-shaped, pale green to gray-green flowers with red-purple streaks, which hang in terminal clusters.
Kalanchoe beauverdii Care
Light
Kalanchoe beauverdii thrives in bright, indirect light. While it can tolerate some partial sun, intense, direct sunlight can scorch its delicate leaves. Conversely, insufficient light leads to leggy growth as stems stretch for illumination. Position the plant near a south or southwest-facing window for ample light without harsh direct exposure.
Watering
Proper watering is important for Kalanchoe beauverdii to prevent root rot. As a succulent, it stores water in its fleshy leaves and stems, making it drought-tolerant. The “soak and dry” method is ideal: water thoroughly until water drains from the bottom of the pot, then allow the soil to dry out completely before watering again. During the active growing season in spring and summer, water about once a week. During the dormant periods in autumn and winter, reduce watering to every two to four weeks.
Soil
A well-draining soil mix is important for Kalanchoe beauverdii to thrive. A specialized succulent or cactus potting mix is recommended to prevent waterlogging. You can also create your own mix by combining potting soil with coarse sand, perlite, or horticultural grit to enhance drainage and aeration. The soil should allow water to pass through quickly, mimicking the rocky and sandy terrains of its native habitat.
Temperature and Humidity
Kalanchoe beauverdii prefers temperatures from 60°F to 85°F (15°C to 29°C). It tolerates average indoor humidity. It is sensitive to frost and should be protected from temperatures below 25°F (-3.9°C). If grown outdoors in colder climates, bring the plant indoors before temperatures drop significantly.
Fertilization
Fertilize Kalanchoe beauverdii sparingly, typically during its active growing season in spring and summer. Use a balanced, liquid fertilizer diluted to half strength, applying it every two to four weeks. Over-fertilization can harm the plant, so follow dosage guidelines carefully. Fertilization is not necessary during the plant’s dormant period in winter.
Growing Kalanchoe beauverdii
Kalanchoe beauverdii is a vining succulent with a vigorous climbing habit, with stems reaching up to 16.4 feet (5 meters). Its slender stems and hooked leaves enable it to clamber and twine around supports. Due to its vining nature, it benefits from a trellis, stakes, or other structures to support its upward growth. Allowing it to cascade from a hanging basket is another suitable option.
This plant can be grown both indoors and outdoors, depending on your climate. For outdoor cultivation, it is best suited for USDA hardiness zones 9b to 11b, where temperatures generally remain above 25°F (-3.9°C). In regions with colder winters, it is typically grown as a houseplant or in containers that can be moved indoors to avoid frost damage.
Propagating Kalanchoe beauverdii
Propagating Kalanchoe beauverdii is straightforward, with stem cuttings being the most effective method. The optimal time is during spring or early summer when the plant is actively growing. To take a cutting, select a healthy, non-flowering stem segment about 2 to 4 inches long and make a clean cut just below a leaf node.
After taking the cutting, allow the cut end to dry and form a callus for one to two days; this step helps prevent rot once planted. Plant the callused cutting in a well-draining succulent or cactus soil mix. Water lightly and place the potted cutting in a warm location with bright, indirect light, avoiding direct sunlight. Roots typically develop within a few weeks, and new growth will emerge.
Common Issues and Solutions
Kalanchoe beauverdii is susceptible to root rot, which typically results from overwatering. Signs include mushy stems or leaves. To address this, reduce watering frequency and ensure the soil dries completely between waterings. Using a well-draining soil mix and a pot with drainage holes helps prevent water from accumulating around the roots.
Pest infestations, such as mealybugs or aphids, can occasionally affect Kalanchoe beauverdii. These can be identified by small, cottony masses or tiny insects on stems and leaves. A solution of insecticidal soap or neem oil can effectively treat these pests. Environmental stress can manifest as stretched, leggy growth (indicating insufficient light) or leaf discoloration (from excessive direct sun). Adjusting the plant’s light exposure can correct these issues.
Safety Considerations
Kalanchoe beauverdii is considered toxic if ingested. All parts of the plant are harmful to humans and animals, particularly pets such as cats and dogs. Ingestion can lead to symptoms that affect the heart and nervous systems.
Position Kalanchoe beauverdii out of reach of children and pets. If accidental ingestion occurs, seek immediate medical or veterinary attention.
