Cyperus Papyrus Care: Light Is the Missing Ingredient

Papyrus (Cyperus papyrus) is a full-sun plant. Indoor leaf dieback on older foliage is normal when light drops. Move it to your sunniest window; new growth will adapt. Keep soil constantly moist (standing water is fine). If tap water is hard, use filtered or rainwater to prevent tip burn. Go easy on fertilizer. Its cousin, Cyperus alternifolius, tolerates lower light better.
