Kalanchoe longiflora coccinea is an appealing succulent known for its unique appearance and straightforward care. Its striking foliage offers a distinctive visual element, popular for its ornamental value and minimal attention needs. It adapts well to indoor environments.
Understanding Your Kalanchoe longiflora coccinea
Kalanchoe longiflora coccinea, also known as Tugela Cliff-Kalanchoe or Long-Flower Kalanchoe, is a captivating succulent native to South Africa, particularly found growing on rock faces and shale slopes in the Tugela basin. This plant typically grows as a narrow bush, reaching heights of up to 12 to 16 inches (30.5 to 40 cm) tall. Its branches are often quadrangular and can sprawl, with the tips turning upwards. The plant’s most notable feature is its thick, fleshy leaves, which are shell-shaped with a wedge-like base and distinct jagged or tooth-like edges. These leaves are typically bluish-gray or green, but they develop striking pink to reddish-brown margins, or even turn entirely reddish, especially when exposed to ample sunlight. This vibrant coloration adds significant ornamental appeal, making Kalanchoe longiflora coccinea a favored choice for container gardens, rock gardens, and arid landscapes.
Caring for Kalanchoe longiflora coccinea
Light
Kalanchoe longiflora coccinea thrives in bright, indirect light conditions. Direct, intense midday sun can scorch its leaves, causing damage. For indoor cultivation, placing the plant near a south-facing window in the Northern Hemisphere provides sufficient illumination, though it should be positioned slightly away from the glass to avoid direct, harsh rays. Adequate light exposure is also crucial for developing the vibrant reddish hues along the leaf margins, intensifying their coloration.
Watering
As a succulent, Kalanchoe longiflora coccinea has adapted to store water in its leaves and stems, necessitating an infrequent watering schedule. The most effective method involves thoroughly drenching the soil until water drains from the bottom of the pot, then allowing the soil to dry out completely before the next watering. Overwatering is a common issue that can lead to root rot, which is detrimental to the plant’s health. Checking the soil moisture by inserting a finger or a stick a couple of inches deep can help determine if it is dry enough for another watering.
Soil
Optimal growth for Kalanchoe longiflora coccinea depends on a well-draining soil mix that prevents waterlogging around the roots. A specialized cactus or succulent potting mix is highly recommended due to its coarse, gritty nature. Enhancing drainage further can be achieved by amending the soil with mineral grit such as coarse sand, pumice, or perlite, typically in equal parts with the potting mix. Ensuring the planting container has adequate drainage holes is equally important for the plant’s well-being.
Temperature and Humidity
Kalanchoe longiflora coccinea prefers mild to warm conditions, ideally thriving in temperatures ranging between 60°F and 85°F (15°C to 29°C). It is not tolerant of cold temperatures and will not survive frost, making it advisable to bring outdoor plants indoors if temperatures drop below 30°F (-1.1°C). While it can tolerate typical indoor humidity levels, excessive humidity is generally not beneficial. Maintaining good air circulation around the plant can help prevent fungal issues.
Fertilizing
Fertilizing Kalanchoe longiflora coccinea should be done sparingly, as succulents do not require frequent nutrient boosts. During its active growing season, typically spring and summer, a balanced liquid fertilizer can be applied. It is recommended to dilute the fertilizer to half or even a quarter of the strength suggested on the product label. Fertilization once a month or bi-weekly during this period is generally sufficient to support healthy growth. During the dormant winter months, it is best to withhold fertilization entirely.
Propagating Kalanchoe longiflora coccinea
Stem Cuttings
For stem cuttings, select a healthy, non-flowering stem and cut a section with several leaves. After making the cut, allow the severed end to “callous” or dry for a few days; this forms a protective seal that prevents rot when planted. Once calloused, the cutting can be planted in a well-draining succulent soil mix.
Leaf Cuttings
Leaf cuttings also offer a viable propagation method. Gently remove a healthy, intact leaf from the plant, ensuring the base is complete. Similar to stem cuttings, allow the leaf to callous for a few days before placing it on top of or slightly inserted into moist, well-draining soil. With both methods, maintaining bright, indirect light and providing minimal moisture will encourage root development and the growth of new plantlets.
Common Issues and Solutions
Root Rot
One of the most prevalent issues encountered with Kalanchoe longiflora coccinea is root rot, which typically results from overwatering. Signs of root rot include mushy stems or leaves and a general decline in plant vigor. To address this, promptly remove the plant from its pot, trim away any diseased or soft roots, and repot it in fresh, dry, well-draining succulent soil. Adjusting the watering schedule to allow the soil to fully dry between waterings is crucial for prevention.
Lack of Coloration and Pests
A lack of the characteristic reddish coloration on the leaf margins often indicates insufficient light exposure. While the plant needs bright light to develop these hues, ensure it’s not receiving harsh, direct afternoon sun, which can cause sunburn. Relocating the plant to a brighter spot, such as near a south-facing window with filtered light, can help restore its vibrant colors. Common succulent pests, such as mealybugs and aphids, can also affect Kalanchoe longiflora coccinea. Inspecting the plant regularly for these small insects and treating infestations with insecticidal soap or neem oil can effectively control them.
