Check these first
- Observe the amount of sunlight the plant gets.
- Check for nearby trees or structures blocking the light.
- Look for signs of new growth near the base.
Likely causes
Insufficient Light
Most likelyHow to tell: The branches stretch out with large gaps between the leaves, and the plant looks thin or sparse. It will lean toward the nearest light source.
What to do: Move the shrub to a location that receives full sun to partial shade. If it is in deep shade, consider trimming back nearby trees to let more light reach it.
Lack of Pruning
PossibleHow to tell: The plant grows tall and spindly with old, woody branches that lack foliage. It loses its characteristic compact shape.
What to do: Prune the shrub in late winter or early spring to encourage thicker growth. Cut back long, straggly branches by one third to stimulate new buds.

When to worry
It is normal for a young plant to grow quickly before filling out. Worry only if the plant looks weak and fails to produce leaves on the lower branches.
Stopping it coming back
Ensure the plant receives at least 6 hours of sunlight and prune it annually to maintain its shape.
