Kalanchoe tomentosa ‘Nigra’, also known as “Panda Plant Black,” is a distinctive succulent. This cultivar stands out with its exceptionally dark, velvety foliage, covered in fine, dense hairs that give them a soft, felt-like texture and a deep, almost black coloration. This compact plant makes an attractive addition to any succulent collection, offering a striking contrast to lighter-colored plants.
Kalanchoe Nigra Care
Light Needs
Kalanchoe tomentosa ‘Nigra’ thrives in bright, indirect light. A south-facing window provides ample light without harsh direct sun exposure. Too much direct sunlight, especially during peak afternoon hours, can scorch its delicate, hairy leaves, leading to brown spots. Insufficient light may cause the plant to stretch, resulting in leggy growth and diminished leaf color.
Watering Practices
Proper watering is crucial for Kalanchoe ‘Nigra’. Allow the soil to dry out completely between waterings to prevent root rot. When watering, thoroughly drench the soil until water drains from the bottom of the pot, then discard any excess water in the saucer. Watering frequency varies seasonally, with less needed in cooler, dormant months and more during active growth in spring and summer.
Soil Requirements
A well-draining soil mix is fundamental for Kalanchoe ‘Nigra’ to flourish. This prevents waterlogging around its roots. A specialized succulent or cactus potting mix, containing sand, perlite, or pumice, provides necessary drainage and aeration. Adequate drainage holes are equally important to facilitate water runoff and maintain healthy root conditions.
Temperature and Humidity
Kalanchoe ‘Nigra’ prefers average household temperatures, ideally 60°F to 75°F (15°C to 24°C). It tolerates slightly cooler temperatures but needs frost protection, as it is not cold-hardy. While adaptable to typical indoor humidity, it is susceptible to issues in overly humid environments. High humidity promotes fungal diseases and rot, so good air circulation is beneficial.
Fertilization
Kalanchoe ‘Nigra’ is not a heavy feeder, requiring minimal fertilization. If desired, apply a balanced liquid succulent fertilizer, diluted to half strength. Do this sparingly during its active growing season in spring and summer. Avoid fertilizing during dormant winter months to prevent stress and nutrient burn.
Propagating Kalanchoe Nigra
Propagating Kalanchoe tomentosa ‘Nigra’ is straightforward, commonly achieved through stem or leaf cuttings. For stem cuttings, snip a healthy section with at least two sets of leaves. For leaf cuttings, gently twist a leaf from the main stem, ensuring a clean break. Allow cuttings to air dry for several days until a callus forms over the cut end.
Callusing prevents rot when the cutting is planted. Once callused, plant the cutting in a well-draining succulent potting mix. Lightly mist the soil every few days to encourage root development without saturation. Roots typically form within a few weeks, after which you can gradually transition to a regular watering schedule.
Troubleshooting Common Problems
Overwatering often leads to mushy stems or yellowing, dropping leaves. If these symptoms appear, reduce watering frequency and ensure the soil dries completely between applications. Conversely, shriveling or wrinkling leaves indicate underwatering, signaling the plant needs more consistent moisture, though still allowing for dry periods.
Light problems also affect this succulent’s appearance. Insufficient light causes etiolation, where stems elongate and stretch. Providing brighter, indirect light encourages more compact growth. Direct, intense sunlight can cause leaf scorch, appearing as brown or reddish patches on the foliage, requiring relocation to a shadier spot.
Pests like mealybugs and spider mites can infest Kalanchoe ‘Nigra’. Mealybugs appear as white, cottony masses in leaf axils; spider mites cause fine webbing and tiny dots on leaves. Wipe mealybugs with a cotton swab dipped in rubbing alcohol. Manage spider mites with a strong spray of water or insecticidal soap. Ensure good air circulation to deter fungal issues, which can arise from persistent moisture on leaves or overly humid conditions.
