Frequently asked questions

How often should I water Kalanchoe?

Water when top inch is completely dry. Every 10–14 days in summer; every 3–4 weeks in winter. Never in standing water. In practice, water every 10–14 days in summer; every 3–4 weeks in winter. Push finger or skewer to the bottom of the pot; only water when fully dry. Reduce sharply in winter when short days slow growth; wet cold soil causes rot.

What light does Kalanchoe need?

Kalanchoe needs bright, indirect light for steady indoor growth.

Is Kalanchoe toxic to pets?

Kalanchoe is toxic to cats, dogs, rabbits, horses, turtles, and tortoises. Keep out of reach of curious pets and choose pet-safe alternatives for accessible spots.

How do I propagate Kalanchoe?

Propagate Kalanchoe from healthy stem or root divisions during active growth.

What soil is best for Kalanchoe?

Use very fast-draining succulent mix: cactus blend 50% + perlite 30% + coarse grit 20%. Terracotta preferred. A good mix includes cactus and succulent mix, perlite (30%), coarse grit or pumice. Excellent drainage is essential; terracotta or mineral mixes preferred. Target soil pH around 6.0–7.5.

When should I repot Kalanchoe?

Repot Kalanchoe every 2–3 years after bloom or when root-bound; avoid oversize pots, ideally in spring. Signs it needs a bigger pot: roots escaping drainage holes, plant unstable in pot, soil depleted and compacted.
