How to Propagate Aglaonema
Aglaonema is one of the easiest houseplants to propagate. Here are three reliable methods — choose the one that fits your comfort level and available supplies.
Division method
You will need a clean knife or scissors and fresh potting mix.
- 1 Remove the plant from its pot.
- 2 Gently shake off loose soil to expose the root system and individual stems.
- 3 Identify natural divisions where stems have their own root systems.
- 4 Carefully separate the root balls, ensuring each division has at least 2–3 stems and a healthy root system.
- 5 Pot each division into appropriately sized containers with fresh, well-draining soil.
- 6 Water lightly and place in bright indirect light.
Expected timeline: established in 4–6 weeks, with new growth appearing in 6–10 weeks. Success rate: approximately 90% with healthy divisions.
Success rate: approximately 90% with healthy divisions.
Stem cutting method
You will need a clean sharp knife or scissors, optional rooting hormone, and a small pot with moist propagation mix.
- 1 Select a healthy stem with 2–3 leaves.
- 2 Cut the stem just below a node (the point where leaves attach).
- 3 Remove the lowest leaf to expose the node.
- 4 Dip the cut end in rooting hormone if desired.
- 5 Insert the cutting into moist perlite or a 1:1 mix of peat and perlite.
- 6 Cover loosely with a clear plastic bag to maintain humidity.
- 7 Place in bright indirect light at 70–75°F.
- 8 Keep the mix lightly moist but not soggy.
Expected timeline: roots in 4–8 weeks, new growth in 10–16 weeks. Success rate: approximately 60–75%.
Success rate: approximately 60–75%.
Troubleshooting Common Issues
Division wilts after potting
This is normal transplant stress. Keep the soil lightly moist, maintain high humidity (pebble tray or plastic bag), and place in bright indirect light. The plant should recover in 2–3 weeks.
Stem cutting rots before rooting
The cutting was kept too wet. Use a much grittier mix (more perlite), water less frequently, and ensure the cutting is not buried too deeply. Allow the cut end to callus for a few hours before sticking it in the mix.
No roots after 8 weeks
Aglaonema cuttings are slow to root, especially in cooler temperatures. Increase the temperature to 75–80°F, ensure bright indirect light, and be patient—some cuttings take 3 months to root.
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
