Kalanchoe blossfeldiana (Flaming Katy) Care: Succulent Blooms on Demand

Kalanchoe blossfeldiana—"Flaming Katy"—is a compact succulent with clusters of tiny, star-like flowers in red, orange, yellow, pink, and white. It's a photoperiodic bloomer: give it long nights, and it flowers on cue. Perfect for bright windowsills and gift-giving.

Light

Bright light, some direct sun. East or west window. In summer, protect from harsh noon sun. Low light = red leaf margins, no flowers.

Temperature

55–85°F (13–30°C). Frost kills it fast. Keep above 50°F (10°C) always.

Water: Succulent Rules

Let soil dry completely between waterings. Water thoroughly, drain fully. Never let sit in water. Ceramic pots and pebble base layers help. Avoid wetting leaves.

Reblooming Trick

After flowers fade, cut stems back, reduce water, give 6-week rest. Then: 14-hour nights (darkness) for 6 weeks = new buds. Or buy in bloom and enjoy 8+ weeks of color.

Soil and Pot

Cactus/succulent mix. Small pot—likes being slightly root-bound. Repot annually in spring.

Pests

Mealybugs in leaf axils. Treat with alcohol swabs.
