With its glossy green leaves and unusual blooms, it’s a conversation starter that’s surprisingly easy to care for when you understand its needs.
1. Light: Bright, Indirect Light is Essential
- Ideal Location: Near an east or west-facing window with filtered sunlight
- Light Requirements: 4-6 hours of bright, indirect light daily for optimal blooming
- Avoid: Direct afternoon sun that can scorch leaves
- Signs of Insufficient Light: Few flowers and leggy growth
2. Watering: Consistent but Careful Moisture
- Watering Rule: Water when the top inch of soil feels dry
- Method: Water thoroughly, then allow excess to drain completely
- Seasonal Adjustment: Water more frequently in summer, reduce in winter
- Caution: Avoid waterlogged soil which causes root rot
3. Temperature and Humidity
- Ideal Temperature: 65-75°F during the day, above 60°F at night
- Humidity: Prefers 40-50% humidity – use a pebble tray if air is dry
- Winter Care: Protect from cold drafts and heating vents
4. Soil and Potting
- Soil Type: Use a well-draining potting mix with added perlite
- Container: Choose a pot with drainage holes to prevent waterlogging
- Repotting: Repot every 2-3 years in spring when roots fill the container
5. Feeding for Abundant Blooms
- Growing Season: Feed every 2 weeks with balanced liquid fertilizer
- Bloom Boosting: Use a high-phosphorus fertilizer as buds form
- Winter: Reduce feeding to monthly during dormant period
6. Pruning for Bushier Growth
- Pinching: Regularly pinch back stem tips to encourage branching
- Post-Bloom: Trim back after flowering to maintain compact shape
- Leggy Growth: Cut back long stems by one-third to rejuvenate
7. Encouraging More Flowers
- Key Factors: Bright light, proper feeding, and consistent moisture
- Blooming Season: Typically flowers spring through fall
- Trigger: Slight root restriction often stimulates blooming
8. Easy Propagation
- Stem Cuttings: Take 3-4 inch cuttings with several leaves
- Rooting: Place in moist soil or water, keeping in bright, indirect light
- Timing: Best done in spring or early summer
