Chasing the Sun: Understanding Indoor Plant Lighting

Light is food for your plants. You can have the best soil and a perfect watering routine, but if your plant is sitting in the dark, it won’t survive. Understanding the lighting in your home is crucial for happy indoor plants.

Decoding Light Levels

• Direct Sunlight: The sunbeams hit the plant’s leaves directly. This is usually found right next to a south-facing or west-facing window. Best for: Cacti, succulents, and some citrus trees.
• Bright Indirect Light: The plant is in a very bright room, but out of the direct path of the sun’s harsh rays. Think of a spot a few feet away from a sunny window. Best for: Most tropical houseplants like Monsteras, Calatheas, and Philodendrons.
• Low Light: Spaces far away from windows, or rooms facing north. Note that “low light” does not mean “no light.” Best for: Snake plants, ZZ plants, and Cast Iron plants.

The Quick Shadow Test

Not sure what kind of light your room has? Wait until the brightest part of the day and hold your hand between your plant and the window.
