Growing cinnamon indoors is challenging because cinnamon trees ( Cinnamomum verum) are large tropical trees requiring specific conditions. While you can't grow a full-sized cinnamon tree indoors for harvesting bark, you can grow a Cinnamomum plant as a houseplant. Success depends on replicating its ideal tropical environment.
Creating the Right Environment
Cinnamomum verum thrives in warm, humid climates. To mimic this indoors:
- Humidity: High humidity is crucial. Use one or more of these techniques:
- Place the plant near a humidifier.
- Group it with other humidity-loving plants.
- Set the pot on a pebble tray filled with water (ensure the pot's bottom doesn't sit directly in the water).
- Temperature: Maintain a consistently warm temperature, ideally between 65-80°F (18-27°C). Avoid placing it near drafts, radiators, or heating/air conditioning vents.
- Light: Provide bright, indirect sunlight. A south- or east-facing window (depending on your location and climate) is usually ideal, but avoid direct sun which can scorch leaves.
- Watering: Keep the soil consistently moist, but not waterlogged. Allow the top inch of soil to dry slightly before watering again. Overwatering is a common problem.
- Soil: Use a well-draining potting mix suitable for tropical plants.
Propagation
Propagating cinnamon from seed is possible but slow and requires patience. Cuttings are generally more successful. However, readily available Cinnamomum plants are usually available for purchase from nurseries or online retailers. Choose a healthy, established sapling for the best chance of success indoors.
Potential Challenges
- Leaf Browning: If the edges of the leaves brown, it usually indicates low humidity. Increase humidity using the methods described above.
- Slow Growth: Indoor cinnamon plants will grow significantly slower than those outdoors. This is perfectly normal and expected.
Remember, you won't be harvesting cinnamon bark indoors; this is more about enjoying the plant's beauty and aroma.
