How to Propagate Calathea
Calathea is one of the easiest houseplants to propagate. Here are three reliable methods — choose the one that fits your comfort level and available supplies.
Unlike many popular houseplants, Calatheas cannot be propagated from stem or leaf cuttings. They grow from rhizomes — thick, fleshy underground stems — and the only reliable propagation method is division at repotting time. This means you need a mature, well-established plant with multiple growth points (stems emerging from the soil).
The best time to divide is in spring when you are already repotting. Remove the plant from its pot and gently shake off excess soil to expose the rhizome structure. Look for natural division points where clusters of stems have their own root systems. Using a clean, sharp knife, cut through the rhizome to separate sections, ensuring each division has at least 2–3 healthy leaves and a good root mass. Dust the cut surfaces with cinnamon powder or sulfur to prevent fungal infection.
Pot each division in its own container with fresh peat-based mix. Water with filtered or distilled water and place in a warm, humid spot with medium indirect light. Cover with a clear plastic bag or propagation dome to maintain high humidity during the recovery period, removing it for an hour each day to allow air circulation. New growth typically appears in 3–6 weeks, at which point you can remove the cover entirely and treat the new plant as a mature Calathea. Be patient — divisions can be slow to establish.
Propagation Tips
- ✓ Always use clean, sterilized tools to prevent infection
- ✓ Cuttings need bright indirect light — never direct sun
- ✓ Change propagation water every 5–7 days to prevent bacteria
- ✓ Be patient — rooting takes 2–6 weeks depending on the method
- ✓ Spring and summer are the best seasons for propagation
