How to care for rattlesnake plant
- Light: Requires medium to bright, indirect light; direct sun will scorch and fade its leaves. Low light can reduce leaf color.
- Water: Keep the soil consistently moist but never soggy; allow the top inch of soil to dry out slightly before rewatering. Use distilled or filtered water to avoid mineral buildup.
- Soil: Use a well-draining, moisture-retentive potting mix, such as an African violet mix or regular potting soil amended with perlite and peat moss.
- Temperature: Thrives in warm, consistent temperatures between 65-80°F (18-27°C). Protect from cold drafts and sudden temperature drops.
- Humidity: Demands high humidity, ideally above 60%. Mist frequently, use a humidifier, or place on a pebble tray to prevent crispy leaf edges.
- Fertilizer: Feed with a balanced liquid fertilizer diluted to half strength every 2-4 weeks during the growing season (spring and summer). Do not fertilize in fall and winter.
- Propagation: Best propagated by division during repotting when the plant has multiple growth points. Gently separate rhizomes with roots attached.
