• Often requiring support to keep its heavy foliage upright

Light Requirements

• Bright; indirect light
• Avoid direct sunlight to prevent leaf scorch

Watering & Humidity

• Keep the soil consistently moist with excellent drainage to avoid waterlogging
• High humidity (60% or higher) is essential for optimal growth

Soil & Potting Mix

• A well-draining, loamy mix with added organic matter is best
• A mix of peat, perlite, and pine bark is recommended for optimal growth

Temperature & Fertilizer
