Leggy, pale stems (etiolation): causes and fix
A plant that lacks light stretches toward the window. The stems grow long and thin and the leaves look pale. More light stops new stretching, but old growth stays long.
This is general care advice. Check the label of your plant. Keep toxic plants away from pets and children.
What you need
- Clean scissors or pruning shears
- A brighter spot or a grow light
Steps
- Look at the new stems. Check for long gaps between the leaves. Compare them with the older, compact growth near the soil.
- Check the color of the new leaves. Small, pale leaves are a sign of too little light.
- Check if the stems lean to the window. Leaning stems mean the light comes from one side.
- Move the plant closer to a bright window. Move it a little at a time. A sudden move to strong sun can burn leaves.
- Turn the pot a quarter turn each time you water. The plant then grows evenly.
- Clean the window glass. Dust and dirt block light.
- Use a grow light if the room stays dark, mostly in winter. Run it 12 to 14 hours a day for foliage plants.
- Prune leggy stems with clean scissors, in spring or summer. Cut just above a leaf. New side shoots then grow and the plant gets full.

Warnings
- Stems that already stretched do not become short again. Only new growth will be compact.
- Do not prune a lot at one time. Remove no more than a third of the plant.
- Brown, crisp patches after a move mean the new spot is too bright. See the sunburn guide.
Questions and answers
Why is my plant tall and thin?
The plant gets too little light. It grows long stems to find more light. Move it closer to a bright window.
Can a leggy plant become compact again?
The old stems stay long. With more light, new growth is compact. Prune the long stems so the plant branches.
Can I use cuttings from the pruned stems?
Yes. Many plants root from stem cuttings in water or moist soil. Check the care page for your plant.
