Origin and Botanical Background

While it can grow up to 1.5 m in its native range, it stays more compact indoors, especially with pruning and proper light.
Light and Placement Tips for Vibrant Leaves
 
Ideal Light:Bright, indirect light is best to preserve its color and bushy shape.
 
Filtered Sun: 6–8 hours of soft light daily enhances pigmentation.
 
Avoid Harsh Sun: Direct sun can bleach or scorch delicate leaf tissue.
Watering and Soil Tips to Prevent Root Issues
 
Watering: Let the top 2–3 cm of soil dry out before rewatering.
 
Soil: Use a light, well-draining mix with compost and perlite or coco coir.
 
Bottom-Watering: Encourages strong roots while avoiding soggy surface soil.
 
Water Type: Use filtered or demineralized water to avoid buildup.
Temperature and Humidity: Keep It Tropical
 
Best Range: 18–24 °C, with protection from sudden temperature swings.
 
Humidity: Medium to high preferred — low humidity may lead to browning edges.
 
Tip: Use a pebble tray or group with other plants to maintain humidity if needed.
Potting and Feeding for Fast, Compact Growth
 
Pot Type: Terracotta or breathable ceramic with drainage holes work best.
 
Repotting: Every 1–2 years or when rootbound. Best done in spring.
 
Fertilizer: Use a diluted liquid fertilizer every 2–4 weeks during active growth. Don’t overfeed — can lead to legginess.
Common Issues and How to Fix Them
 
Yellow Leaves: Overwatering. Let soil dry slightly and ensure good drainage.
 
Browning Tips: Often from dry air or inconsistent watering. Increase humidity and monitor routine.
 
Leggy Growth: Not enough light. Move closer to a bright, filtered light source and pinch back tips.
 
Pests: May attract spider mites or mealybugs in dry conditions. Use insecticidal soap, neem oil, or introduce beneficial insects.
 
Root Rot: Caused by poor drainage or standing water. Use a breathable pot and monitor watering.
