Monstera adansonii
A popular tropical climbing vine known for its heart-shaped leaves that develop oval-shaped holes (fenestrations) as the plant matures.
- Light
- Bright, indirect light (6-8 hours daily). Avoid direct sunlight which can scorch the leaves; can tolerate lower light but growth will be slower.
- Water
- Water every 1-2 weeks when the top inch of soil feels dry. Sensitive to overwatering; yellowing leaves and mushy stems indicate root rot.
- Growth
- Perennial evergreen climber. Can reach 10-20 feet long when provided with a moss pole or trellis; grows at a medium to fast rate.
Care instructions
Thrives in bright indirect light and high humidity. Water when the top inch of soil is dry. Use a well-draining aroid mix and feed monthly during the growing season with a balanced liquid fertilizer.

Bright, indirect light (6-8 hours daily). Avoid direct sunlight which can scorch the leaves; can tolerate lower light but growth will be slower.
Watering
Water every 1-2 weeks when the top inch of soil feels dry. Sensitive to overwatering; yellowing leaves and mushy stems indicate root rot.
Soil
Well-draining, peat-based potting mix with perlite or orchid bark to ensure aeration. Prefer slightly acidic to neutral pH (5.5 to 7.0).
