- Grouping: Plant a group of about 5-6 stems to establish a lush backdrop that enhances the visibility of other features.
Care Requirements
Lighting
- Intensity: Medium to high
- Duration: 10-12 hours per day to promote vibrant growth and maintain leaf variegation.
Water Conditions
- Temperature: 22-28°C (72-82°F)
- pH: 6.0-7.5
- Hardness: 2-15 dKH
Substrate
- Type: Prefers a nutrient-rich substrate to support fast growth and healthy root development.
CO2
- Addition: Beneficial but not essential
- Rate: 5-15 mg/L can significantly enhance growth rate and leaf coloration.
Fertilization
- Macro Nutrients: Regular additions are important for sustained growth.
- Micro Nutrients: Supplementing with iron and other trace elements helps maintain the distinct pink coloration of the veins.
Pruning and Maintenance
- Pruning Frequency: Every 4-6 weeks or as needed to control growth and encourage bushier development.
- Trimming Technique: Trim top shoots and replant the cuttings if denser growth is desired.
Propagation
- Method: Easy through cuttings; simply cut the top of a stem and replant in the substrate.
- Growth Rate: Fast, which makes it suitable for filling in background areas quickly.
Common Issues
- Lighting Needs: Insufficient light can lead to leggy growth and less vibrant leaf color.
- Nutrient Deficiencies: Watch for signs of nutrient deficiencies such as pale or yellowing leaves.
Additional Tips
- Plant Density: Planting in dense groups can help prevent algae growth by shading the substrate.
- Regular Check-ups: Regularly check and adjust plant positions to ensure optimal exposure to light and nutrients.
