Dormancy on kalanchoe
What's Happening
Kalanchoe species are winter-growers that require shorter day lengths (10-12 hours) and cooler temperatures to initiate flowering and maintain compact growth. During dormancy, metabolic processes slow, reducing water requirements significantly. Continued summer-level watering causes root rot and weak, leggy growth.
How to Fix It
- 1
1. Provide 10-12 hours of bright light daily in winter to encourage flowering and compact growth
- 2
2. Reduce watering frequency by 50% during winter months - allow soil to dry completely between waterings
- 3
3. Maintain temperatures between 60-70°F (15-21°C) during the day, slightly cooler at night
- 4
4. Withhold fertilizer during dormancy; resume feeding in spring when active growth resumes
- 5
5. Remove spent flowers to encourage reblooming and maintain plant energy
How to Prevent It
Use timers to maintain consistent light schedules seasonally; research specific Kalanchoe variety needs as some flower in winter while others in summer; group winter-growing succulents together for consistent care; ensure excellent drainage and airflow during reduced-growth periods
