Because of the Swiss cheese plant's tropical origins, they grow best in bright, indirect light, or partial shade. They're used to thriving under the cover of large trees in the jungle, and can easily burn if exposed to too many direct sun rays. If direct sunlight is unavoidable, limit their exposure to just two or three hours of sun in the mornings.

Swiss cheese plants like to be consistently moist, but not soaked. While it may seem complicated to strike that balance, you can easily test if your plant is in need of water using an easy trick. Before watering your Swiss cheese plant, stick your finger into the soil about an inch deep—if the soil feels nearly dry-to-the-touch, it's time to water the plant. Plus high humidity!
