Plant Problem Diagnostic
Why Is My Houseplant Leggy and Stretching?
The short answer
Leggy, spindly growth with long stem gaps between leaves means the plant isn't getting enough light and is stretching to reach it. A lean toward one side is the same signal - it's growing toward the light source.
Move it to brighter indirect light (an east or west window for most plants) or add a grow light, since UMD notes the same plant in brighter light would be more compact, better branched, and have normal-size leaves. You can pinch back the stretched growth to encourage bushier regrowth once the light is better.
Reading the signs
Stretched, spindly growth is the plant's response to insufficient light. University of Maryland Extension describes insufficiently lit plants becoming spindly or 'leggy' as they stretch to reach for more light, developing a lean when light comes from one direction, and showing fading leaf color, diminished flowering, and poor growth.
The tell is the spacing: healthy growth has leaves close together, while a light-starved plant puts out long bare stem between small, widely spaced leaves. A plant leaning hard toward the window is confirming the diagnosis.
The fix is light
UMD notes that the same plant grown in brighter light would be more compact, better branched, and have normal-size leaves. So the remedy is more light, not more water or fertilizer - feeding a light-starved plant just produces more weak growth.
Move it to a brighter spot (bright indirect light suits most houseplants) or add a grow light. Rotate the pot every week or two so it grows evenly instead of leaning. If a plant has stretched badly, pinch or cut back the leggy stems once it's in better light to encourage compact, bushy regrowth.
