Kalanchoe ‘Dragonfire’ is a distinctive succulent known for its vibrant foliage and unique blooms. Developed in California in 2015, this hybrid quickly gained popularity as an ornamental plant. Its striking appearance and robust nature make it a favored choice.
Understanding the Dragonfire Bloom
Unlike some Kalanchoe varieties, ‘Dragonfire’ produces delicate, star-shaped blooms with four petals, typically in clusters. While some sources suggested cream or yellow, the common bloom color is white, though some cultivars may produce red, orange, or yellow flowers.
These blooms emerge from green buds in late fall or early winter, continuing through early spring. ‘Dragonfire’ can repeatedly bloom from the same plant for several months, contrasting with some Kalanchoe species that die after flowering.
Cultivating Vibrant Dragonfire Blooms
Encouraging Kalanchoe ‘Dragonfire’ to bloom requires specific environmental conditions and consistent care. Correct light, temperature, watering, and nutrient regimens are essential for initiating and sustaining flowering. Mimicking natural seasonal cues plays a significant role.
Light
Light is key for bloom induction. As a short-day plant, ‘Dragonfire’ requires extended darkness to trigger bud formation. Provide 12 to 16 hours of uninterrupted darkness daily for six to eight weeks before blooming. During the remaining 10 to 12 hours, the plant needs bright, indirect light. Even minimal light exposure during the dark period can prevent flowering.
Temperature
Temperature influences the blooming cycle. ‘Dragonfire’ thrives in mild temperatures, preferring 60-85°F (15-29°C). For bloom initiation, a slightly cooler nighttime temperature around 60°F (15.5°C) can trigger bud setting. While the plant tolerates temperatures down to 45°F (7°C), it is sensitive to frost and needs protection from cold drafts. Consistent temperatures are important, as extreme fluctuations hinder flowering.
Watering
Watering practices adjust to support blooming. As a succulent, ‘Dragonfire’ stores water in its leaves and stems, preferring well-draining soil and sparse watering. Allow soil to dry completely between waterings to prevent root rot. During bloom induction, reduce watering by half to mimic winter conditions and signal flowering. Once flower buds appear, resume regular watering to support active growth.
Fertilization
Fertilization supports plant health and bloom development. ‘Dragonfire’ does not require heavy feeding, efficiently utilizing nutrients from soil and sunlight. During its active growing season (spring and summer), a balanced liquid fertilizer diluted to half-strength encourages growth. Apply fertilizer once a month. A phosphorus-rich fertilizer (e.g., 0-10-10) is recommended in late winter or when buds form to promote abundant blooms.
Rest Period
A rest period, with reduced light and cooler temperatures, is essential for reblooming. This dormancy allows the plant to conserve energy and prepare for its next flowering cycle. After blooming, provide a four to six-week rest with reduced watering and no fertilizer to reset the plant.
After the Bloom Fades
After Kalanchoe ‘Dragonfire’ blooms fade, specific post-flowering care maintains plant health and encourages reblooming. This involves removing spent flowers and adjusting care routines for the next cycle.
Deadheading
Deadheading, the removal of spent flowers, directs the plant’s energy towards new growth. Pinch off dead or dying blooms as they appear. This encourages new buds and keeps the plant tidy. Gently pinch them off or use clean, sharp scissors to snip them at the base of the flower stem.
Pruning
Pruning after blooming maintains the plant’s shape and promotes bushier growth. Trim flower stalks to the second or third leaf below old flowers on each side shoot. Remove any yellow, brown, or decaying leaves and stems at their base. This improves air circulation and reduces pest risk. If leggy, prune back up to a third of each stem’s length to encourage stronger growth.
Adjusting Care Routines
Adjust care routines after blooming to prepare the plant for its next cycle. After pruning, gradually reduce watering and stop fertilizing for four to six weeks. This mimics a dormant period, essential for reblooming. Once new growth appears, gradually resume regular watering and fertilizing during the growing season.
Troubleshooting Bloom Challenges
Kalanchoe ‘Dragonfire’ may not bloom as expected or its flowers may decline prematurely. Addressing these issues involves reviewing environmental conditions and care practices.
Insufficient Light
Insufficient light or an incorrect light/dark cycle is a common reason for lack of flowering. If the plant does not receive 12-16 hours of uninterrupted darkness for six to eight weeks, it will not initiate buds. Even minor light exposure during the dark period can disrupt this. Moving the plant to a location with complete darkness (e.g., a closet or covered with a light-proof box) can resolve this.
Improper Watering
Blooms wilting or fading quickly can signal improper watering. Overwatering, which leads to root rot, frequently stresses succulents. Conversely, allowing the plant to become too dry also causes wilting. Ensure soil dries out completely between waterings and provide adequate drainage to prevent these issues.
Nutrient Deficiencies
Poor bloom color or small flower size may indicate nutrient deficiencies. While ‘Dragonfire’ is not a heavy feeder, a lack of balanced nutrients can impact bloom quality. Fertilize with a diluted, balanced fertilizer during the growing season, or a phosphorus-rich fertilizer when buds form, to support vibrant blooms. Over-fertilizing during blooming can cause the plant to prioritize leaf growth over flowers.
Pests or Diseases
Pests or diseases, though less common with proper care, can indirectly impact blooming by stressing the plant. Fungal root rot, often caused by overwatering in cool, wet conditions, can lead to stunted growth and decline. Inspect the plant regularly and maintain proper watering and humidity to prevent issues. If pests like aphids or mealybugs are present, address them with treatments like neem oil to restore plant health and encourage blooming.
