Leggy growth
Long, thin stems reaching for the light: the plant needs a brighter spot.
What you'll see
- Long, thin stems with wide gaps between the leaves.
- The plant leans or stretches hard toward the window.
- New leaves come in smaller and paler, and variegated leaves may turn plain green.
- Few or no flowers, and lower leaves may yellow and drop.
Why it happens
With too little light, the plant spends its energy stretching toward brighter light instead of growing compact.
How to fix it
- Move it closer to a bright window, or measure a better spot with the light meter.
- Add a grow light close above the plant, for about 12 to 16 hours a day.
- Cut stretched stems back to just above a leaf joint so bushier side shoots form.
- Water less often while the light stays low.
Keep it from coming back
- Match each plant to the light you really have.
- Keep windows and leaves free of dust.
- Give the pot a quarter turn now and then so it grows evenly.
