Check these first
- Observe how many hours of direct sun the plant gets.
- Check if nearby plants are shading it.
- Look for new growth at the base of the stems.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant is stretching toward the nearest light source.
What to do: Move the plant to a location that receives at least 6 to 8 hours of direct sunlight daily. If it is in a shaded area, it will continue to stretch.
Lack of Pruning
PossibleHow to tell: The plant has long, trailing stems that look sparse at the base. It has not been trimmed back in a long time.
What to do: Trim back the long stems by one third to encourage fuller, bushier growth. Do this in the early spring to promote a dense mat.

When to worry
Legginess is rarely fatal but it does make the plant look untidy. If the plant is not flowering, it is a sign that it definitely needs more sun.
Stopping it coming back
Provide full sun exposure and trim the plant annually to keep it compact and healthy.

Questions people ask
- Can I prune my Sunshine Mimosa anytime?
- It is best to prune in early spring before the main growing season. This helps the plant put its energy into new, dense growth.
- Will more sun fix the legginess?
- More sun will stop the plant from stretching further, but it will not fix the existing long stems. You should prune the long stems to encourage new, compact growth.
