Caring for Anthurium queremalense



 
Light: Bright, indirect light preferred. Avoid harsh sun to protect the velvety surface.

Repotting: Every 1–2 years when roots become crowded. Always use breathable pots with excellent drainage.
 
Fertilizing: Light feeding every 6–8 weeks during active growth with a diluted balanced liquid fertilizer.
 
Propagation: Best by thick basal stem division; delicate aerial roots should be preserved if present.

Leaf Browning: A sign of low humidity or water quality issues. Raise humidity and use rainwater or distilled water.
 
Root Rot: Caused by excess moisture. Use very airy substrate and water carefully.
 
Fungal Leaf Spot: Improve air circulation and avoid wetting the leaves when watering.
