Pocket Botanist
Check these first
- Observe if the plant is leaning toward a light source.
- Check if the plant is crowded by other vegetation.
- Assess if the current location provides enough direct sun.
Likely causes
Low Light Conditions
PossibleHow to tell: The stems are thin, elongated, and leaning heavily toward the nearest light source. The plant looks stretched out rather than bushy and upright.
What to do: Relocate the plant to a sunnier position where it can receive direct light. If the plant is in a container, move it to a spot with fewer obstructions.
Overcrowding
PossibleHow to tell: Multiple plants are competing for the same space and light, causing them to grow tall and thin. This often happens in small containers or crowded pond edges.
What to do: Divide the plant into smaller clumps to give each section more room to grow. Replant them with enough space to ensure each stem gets adequate light.

When to worry
Some stretching is normal during early spring growth. Worry if the stems become so weak they cannot support their own weight.
Stopping it coming back
Provide consistent full sun and divide the plant every 2 to 3 years to prevent overcrowding.

Questions people ask
- Can I trim back leggy stems?
- Yes, you can trim back overly long stems to encourage bushier growth. Ensure you leave enough foliage for the plant to photosynthesize.
- Will moving it to the sun fix the legginess?
- Moving it to more light will stop new growth from being leggy. The existing long stems will not shrink, but the plant will look better as it grows.
