Likely causes
Low Light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the light source.
What to do: Move the plant to a location with full, direct sun. Rotate the pot every week to ensure even growth on all sides.
Lack of Pruning
PossibleHow to tell: The plant is tall but lacks density and bushy side growth. The branches are long and sparse.
What to do: Prune back the long, thin stems to encourage branching. This will force the plant to grow fuller and more compact.

When to worry
Legginess is not fatal, but it indicates the plant is struggling to thrive. It is normal for a plant to grow slightly faster in spring, but it should not look thin.
Stopping it coming back
Keep the plant in full sun and prune it regularly to maintain a dense shape.

Questions people ask
- Will the leggy stems fill in?

- How much should I prune?
- You can safely remove up to 20 percent of the foliage at once. Focus on cutting back the longest, thinnest branches.
