Essential Care
Requires bright, filtered light to maintain its dramatic coloration and prevent scorching. Direct sunlight will fade the distinctive dark green color and burn the glossy leaves.
- Ideal: East/west windows with sheer curtains
- Distance: 3-6 feet from bright windows
- Avoid: Direct afternoon sun, deep shade
Keep soil consistently moist but never waterlogged. Allow the top layer to dry slightly between waterings — typically every 5-7 days depending on humidity and season.
Water when top inch feels dry to touch. Ensure excellent drainage as standing water quickly causes root rot in this sensitive cultivar.
Temperatures between 65 to 85°F (18 to 29°C) provide optimal conditions. Avoid temperatures below 60°F and protect from cold drafts that stress the plant.
Consistent warmth is crucial — temperature fluctuations cause leaf drop and stunted growth. Use heating mats in winter if necessary.
Appreciates 60–80% humidity for optimal leaf quality and growth. Most UK homes sit at 30–50%, so supplementation is usually needed.
Use humidifiers, pebble trays, or group with other plants. Low humidity causes crispy edges and smaller new leaves.
A chunky, well-draining aroid mix is ideal. Orchid bark, perlite, maybe some charcoal creates the perfect balance of drainage and aeration.
Mix: Equal parts orchid bark, perlite, coco coir. Add charcoal for extra drainage and root health.
Feed with a balanced plant feed at regular intervals during spring through fall. Reduce feeding in winter when growth slows.
Use diluted liquid fertilizer every 4-6 weeks. Overfertilising causes more problems than underfeeding.
