Your Rhaphidophora prefers very bright, indirect light. It can survive in medium light conditions but may stop growing or produce smaller leaves. Do not put it in full, direct sunlight–the sun will burn the foliage. Water your Rhaphidophora when the top 75% of the soil is dry. Water until liquid flows through the drainage hole in the bottom of the pot. Be sure to empty any excess water that collects in the saucer. Yellow leaves may indicate over watering, while brown leaves mean the plant needs more water.
