If watering is the thing people get wrong most often, light is the thing they underestimate most often. Almost every “low-light” plant actually grows better with more light — it merely survives in less.

Know your windows

Light in a room drops off far faster than your eyes suggest. A spot one metre from a bright window may get a fraction of the light the windowsill gets.

  • South-facing windows (in the northern hemisphere) give the strongest light.
  • East and west windows give moderate light, with a few hours of direct sun.
  • North-facing windows give gentle, indirect light all day.

Match the plant to the spot

  • Bright, direct sun: succulents, cacti, citrus.
  • Bright, indirect light: monstera, fiddle-leaf fig, most flowering plants.
  • Medium light: pothos, philodendron, peace lily.
  • Low light (tolerated, not preferred): snake plant, ZZ plant, cast-iron plant.

Signs of too little or too much

A plant short on light grows leggy — long, pale stems reaching toward the window, with small leaves and wide gaps between them. Variegated plants lose their patterns and turn plain green.

Too much direct sun shows up as bleached or scorched patches, especially on thin-leaved plants behind glass that magnifies the heat.

If your home is dark

A simple LED grow light on a timer (10–12 hours a day) solves the problem cheaply and lets you keep plants in rooms that would otherwise be impossible.
