Pale, elongated growth associated with insufficient light.
What it means for your plants
Long gaps between leaves and weak new growth can be clues, though growth patterns vary by species. Improve light gradually and check other stresses. Fertilizer does not replace missing light.
IN PRACTICE
A pothos kept too far from a window may produce increasingly spaced leaves along a thin vine.
Put it into practice
Choose houseplants for dimmer rooms while understanding the difference between surviving low light and growing well.
