4-8 weeksPlant develops dense, compact rosette form; foliage thickens and matures; 6-12 inches tall
Maintain bright light; allow soil to dry between waterings; feed monthly with dilute succulent fertilizer
Flowering Induction
4-6 weeksFlower buds form at stem tips; requires photoperiod manipulation (long nights trigger blooming)
Provide 13-14 hours of darkness daily for 4-6 weeks to induce flowering; reduce watering slightly; cool nights (50-60°F) enhance flowering

Fun Facts
- 🌱 Kalanchoe Flaming Katy was originally a seasonal plant forced into bloom by commercial growers using precise photoperiod control; this is why home plants often refuse to bloom without long-night conditions (13-14 hours of darkness).
- 🌱 The plant is toxic to cats and dogs, causing gastrointestinal upset and heart arrhythmias if ingested, so it should be kept away from curious pets.
- 🌱 Some cultivars produce variegated foliage with cream or pink edges, adding ornamental interest even when not in bloom.
