How to Grow and Care for Kalanchoe Dragonfire
Learn to maintain a healthy Kalanchoe Dragonfire. This guide covers foundational care and the specific techniques to develop its deep red leaf margins.
The Kalanchoe Dragonfire is a striking succulent, recognized for its large, paddle-like leaves. This plant is a specific cultivar of Kalanchoe luciae, developed in California in 2015. Its fleshy, blue-green leaves feature vibrant magenta or deep red edges that intensify with greater sun exposure. The plant’s structure grows in a rosette pattern, with new leaves emerging from the center and stacking outwards. Its low-maintenance nature makes it a popular choice for both new and experienced gardeners.
Kalanchoe Dragonfire Care Essentials
Kalanchoe Dragonfire requires several hours of bright, direct sunlight each day for healthy growth. While it can tolerate partial sun, sufficient light is needed to maintain its unique coloration. Placing the plant near a window with bright, filtered light is a good strategy to prevent scorching from intense, unfiltered sun.
A well-draining soil mix is a priority to prevent root rot. A commercial succulent or cactus mix works well, or you can amend a standard potting mix with perlite or sand to improve drainage. The container must have drainage holes to allow excess water to escape.
Follow the “soak and dry” method by thoroughly saturating the soil and then allowing it to dry out completely before the next watering. Before adding more water, check that the top one to two inches of soil are dry. Overwatering is a common issue with this drought-tolerant plant, so it is better to water less frequently.
This succulent prefers average household temperatures between 60 and 85 degrees Fahrenheit and is not frost-tolerant. It should be protected from cold drafts and brought indoors if temperatures are expected to drop. The plant has minimal fertilizer needs, but if you choose to fertilize, a diluted succulent fertilizer can be applied once or twice during the spring and summer growing season.
How to Get the ‘Dragonfire’ Red Color
The intense red and magenta hues on the leaf margins are a direct response to environmental “stress,” primarily triggered by high levels of direct sunlight. This benign stress is a desirable trait that many gardeners encourage for aesthetic purposes. The plant changes color to protect itself from the sun, much like a suntan on human skin.
To achieve this coloration without harm, acclimate the plant to increased sunlight gradually. A sudden move from a low-light environment to full, direct sun can cause the leaves to scorch or turn yellow. Start by placing it in an area that receives morning sun, then slowly increase its exposure to more intense afternoon light over several weeks.
Cooler temperatures can also contribute to deepening the red tones of the foliage. While the plant must be protected from frost, exposure to cooler air (around 40 to 50 degrees Fahrenheit) can enhance its color. This temperature-induced stress works with sunlight to produce the most dramatic “Dragonfire” effect.
It is important to find a balance, as too much stress can be detrimental. Leaf edges that become dry or brittle may be a sign of insufficient water or excessive sun exposure. If the red color begins to fade, it means the plant is not receiving enough light.
Propagating and Repotting
Propagate Kalanchoe Dragonfire using the small offsets, or “pups,” that grow at the base of the main plant. Gently separate them once they have developed their own small root system. After removal, allow the offset’s base to dry and form a callus for a few days before planting it in well-draining soil to prevent rot.
This succulent is a slow grower and does not require frequent repotting, needing a new container only every two to three years or when it becomes root-bound. When selecting a new pot, choose one that is only one size larger than the current one. The best time for repotting is during the active growing seasons of spring or summer.
Solving Common Issues
A common problem is etiolation, or stretching, caused by inadequate light. This results in a tall, leggy plant with pale leaves and weakened stems. To fix this, move the plant to a location with more direct sunlight.
Root rot is the most frequent care issue and is a direct consequence of overwatering or poor drainage. Signs of root rot include a mushy stem base and yellowing leaves that may fall off easily. You should also keep an eye out for common succulent pests like mealybugs, which appear as small, white, cottony masses on the leaves and stems.
