Kalanchoe ‘Dragonfire’ is a striking succulent, admired for its distinctive appearance and low-maintenance nature. It features vivid apple-green leaves with fiery red margins, which intensify in color under specific environmental conditions. This plant is a popular choice for both indoor and outdoor spaces.
Getting to Know Kalanchoe Dragonfire
Kalanchoe ‘Dragonfire’ is a hybrid succulent, developed in California in 2015 from a cross-pollination between Kalanchoe luciae and another unnamed hybrid. It has thick, fleshy leaves and stems, growing in a loose rosette formation, typically reaching 4 to 6 inches tall. The vibrant red edges deepen in color with cooler temperatures or higher light intensity, a phenomenon sometimes called “happy stress.” While many Kalanchoe species are known for their blooms, ‘Dragonfire’ is valued for its eye-catching foliage, though it can produce small, delicate white flowers. Its Madagascar origins indicate a preference for well-draining soil and ample sunlight.
Essential Care Requirements
Light
Kalanchoe ‘Dragonfire’ thrives in bright, indirect sunlight indoors. It can tolerate some direct morning sun, but prolonged exposure to harsh afternoon sunlight can scorch its leaves. Outdoors, choose a location with full sun to partial shade, protecting it from intense midday rays. Insufficient light leads to leggy growth and reduced red coloration.
Watering
Kalanchoe ‘Dragonfire’ requires infrequent watering, following a “soak and dry” method. Allow the soil to dry out completely between waterings to prevent root rot. Overwatering can lead to mushy leaves and a foul smell, while underwatering might cause leaves to shrivel. Watering frequency varies by sun exposure and season; less water is needed in spring and fall, with a slight increase during summer.
Soil
A well-draining soil mix is important for Kalanchoe ‘Dragonfire’ to prevent waterlogging and root rot. Use a specialized succulent or cactus potting mix, or create your own by incorporating perlite or sand into regular potting soil. The pot must have drainage holes.
Temperature and Humidity
Kalanchoe ‘Dragonfire’ prefers mild temperatures, ideally between 60-85°F (15-29°C). It is not frost-tolerant; protect it from temperatures below 45-50°F (7-10°C) to prevent damage. Kalanchoes tolerate lower humidity but thrive best between 40-60%. Excessive humidity can contribute to fungal diseases like powdery mildew.
Fertilizing
Kalanchoe ‘Dragonfire’ generally does not require extensive fertilization. If desired, apply a balanced liquid fertilizer diluted to half-strength during the active growing season (spring and summer). Fertilizing infrequently, perhaps once every few months, is sufficient. Avoid fertilizing during the plant’s dormant period, usually in summer or winter.
Ongoing Plant Maintenance
Pruning
Pruning Kalanchoe ‘Dragonfire’ helps maintain its shape and encourages bushier growth. Remove any dead, yellowing, or leggy stems and spent flowers. This directs the plant’s energy towards new, healthy foliage. Use clean, sharp pruning shears for precise cuts.
Repotting
Repotting is typically needed every one to two years, or when the plant becomes root-bound (indicated by roots growing out of drainage holes or slowed growth). The best time is during the active growing season (spring to early summer). Choose a container one size larger with drainage holes and use fresh, well-draining succulent potting mix. Gently remove the plant, shake off old soil, and place it in the new pot, filling with fresh mix.
Troubleshooting Common Issues
Pests and Diseases
Kalanchoe ‘Dragonfire’ can encounter common succulent pests like mealybugs, aphids, spider mites, and scale insects. These pests feed on plant sap, causing discolored leaves or stunted growth. Treat infestations by isolating the plant and applying insecticidal soap or wiping affected areas with a damp cloth.
Root rot is common, primarily caused by overwatering or poorly draining soil, with symptoms including wilting leaves, a foul smell, or mushy roots. Powdery mildew can appear as a white coating on leaves, often due to high humidity and poor air circulation. Proper watering and good air circulation help prevent these issues.
Growth and Color Problems
Leggy growth (long, stretched stems with sparse leaves) indicates insufficient light. Move the plant to a brighter location or supplement with grow lights. Brown or mushy leaves often signal overwatering and potential root rot, requiring an adjustment to watering habits. A loss of vibrant red coloration on leaf margins suggests insufficient intense light, as this color intensifies under higher light or cooler conditions.
