Light: Place the Stromanthe in medium to bright, indirect light. Avoid direct sunlight as harsh rays may cause leaf burn. A northern or eastern facing window typically works well.
Water: Keep the soil evenly moist but not soggy. Use a well-draining soil and allow only the top 10-15% of soil to go slightly dry before watering thoroughly during the growing season. Reduce watering slightly in the winter months. Over-watering can cause yellowing leaves, and under-watering will cause the leaves to curl inward and eventually brown, beginning at the edges.
Environment: Stromanthe need warm, humid conditions to keep leaves looking healthy. While misting year round can be beneficial, during winter, place your plant on a wet pebble tray or near a humidifier in addition to misting. Low humidity causes the leaves to turn brown and become crispy on the edges. Avoid placing near drafts, radiators, and AC units.
Toxicity: Reported to be non-toxic
- Use a light soil that retains moisture but drains well. A peat-based potting soil is a good choice for a Stromanthe. An all-purpose potting soil will suffice.
- Stromanthe does well in shallow containers. Be sure a Stromanthe has outgrown the existing pot before moving it to a larger one; this helps prevent over-watering and root rot.
- Add an all-purpose, water soluble fertilizer to a Stromanthe every 2–4 weeks while the plant is actively growing, usually from early spring to the end of fall.
