brown tips on Calathea Roseopicta
Quick answer
If your Calathea Roseopicta has brown tips, the most likely cause is: Calathea roseopicta, like the rest of the genus, develops best in humidity of 50 percent or greater. When ambient humidity drops below that threshold, the foliage — which is prized for its dazzling dramatic markings and colors — develops brown edges on the leaves as the tissue desiccates at the margins.
Start here:
- 1. Raise and hold ambient humidity at 50 percent or greater around the plant by running a room humidifier near the pot or by placing the pot on a pebble tray with water kept just below the pebble tops so evaporating moisture lifts local relative humidity without wetting the foliage.
- 2. Keep the plant in diffused light and average room temperatures away from drafts and heating vents, since warm moving air accelerates the moisture loss that drives the brown edges in the first place.

Keep brown tips off this Calathea Roseopicta
Calathea roseopicta wants humidity of 50 percent or greater as a standing condition; measure with a hygrometer and maintain it year-round, place the plant in bright indirect light, and protect it from dry heat sources so marginal leaf scorch never gets started.
