Light
Bright, indirect, or low — match the plant to the window.
Three levels
Every plant falls into one of three light needs. Getting this right is half the battle.
Match the window
bright indirect — a few feet from a south window medium — near a north window, or across the room low — pothos, snake plant, zz. the survivors
Read the leaves
Stretching stems and pale leaves mean not enough light. Scorched brown patches mean too much direct sun.
