Harvest Tips
Not a harvested plant. Remove dead, damaged, or yellowing leaves as they appear by cutting at the base of the petiole. Pinch off leaf tips if brown edges occur (sign of fluoride sensitivity). Occasional leaf loss is normal and beneficial for plant health
Fun Facts
- 🌱 Calathea leaves display nyctinasty—a daily movement where leaves fold up at night (like hands in prayer), hence the common name 'Prayer Plant.' The pinkish undersides become visible during this nightly closure
- 🌱 The name 'roseopicta' literally means 'rose-painted,' referring to the rosy-pink variegation that intensifies as the plant matures and receives proper lighting
- 🌱 Unlike many houseplants, Calathea strongly prefers distilled or filtered water; tap water's chlorine and fluoride content causes brown leaf tips and edge burn, a condition called fluoride toxicity
