How much light does my houseplant need?
Light levels explained
Light needs vary widely. Low-light plants like pothos, snake plants, and ZZ plants can survive in a few feet from a north-facing window. Medium-light plants such as philodendrons and peace lilies prefer bright, indirect light—think a spot near an east or west window with a sheer curtain. High-light plants like succulents, cacti, and citrus need several hours of direct sun, usually from a south-facing window.
The intensity drops quickly as you move away from a window. A spot 3 feet from a window may get only 10% of the light available right at the glass. That's why a plant labeled 'low light' might still struggle in a dim corner.
How to tell if your plant is happy
Watch for clues. Stems stretching toward the light, small pale leaves, or a lack of new growth suggest too little light. Brown, scorched patches on leaves or faded colors can mean too much direct sun. Adjust gradually—moving a plant from low to bright light suddenly can shock it.
If natural light is scarce, supplement with a grow light. Even a basic LED bulb in a desk lamp can help. Aim for 12–16 hours of light per day for most foliage plants if using artificial light.
- Low light: survives 6+ feet from a window or in a north-facing room.
- Medium light: 3–6 feet from an east/west window, or filtered south light.
- Bright indirect: right near an east/west window, or a few feet from a south window with a sheer curtain.
- Direct sun: within 2 feet of a south or west window, but only for sun-loving plants.
- Rotate plants weekly for even growth.
Common mistakes
- Assuming a 'low-light' plant can live in a windowless room—it still needs some natural or artificial light.
- Placing a sun-loving succulent in a dark corner and wondering why it stretches.
- Thinking that more light is always better—too much direct sun can burn leaves.
