Calathea Rattlesnake Care
Light: Calathea Rattlesnake plants prefer indirect sunlight. Any room with a bright window will do, and stay 3 to 6 feet away from the nearest light source.
Water: A Calathea Rattlesnake plant should be watered when it has completely dried out. It can even stay dry for a day or two and still thrive.
Humidity: They like any environment. Average household humidity is great. Higher humidity may lead to extra growth, so a spray or water always helps.
