Pocket Botanist
Check these first
- Observe how many hours of direct sun the plant gets.
- Look for gaps between the leaf nodes on the stems.
- Check if the plant is competing with nearby trees for light.
Likely causes
Insufficient light
Most likelyHow to tell: The stems look thin and stretch out with large gaps between the leaves. The plant will often lean heavily toward the nearest light source.
What to do: Move the plant to a spot that receives full sun or very bright partial shade. If it is in a dark corner, it will continue to stretch to find light.
Lack of pruning
PossibleHow to tell: The plant looks sparse and spindly because it has not been encouraged to branch out. Old growth remains long and thin without any new side shoots.
What to do: Prune back the long, leggy stems in late winter or early spring. This encourages the plant to grow denser and bushier when the new season starts.

When to worry
A little bit of stretching is normal as the plant reaches for the sun. Worry if the stems become so weak they cannot support their own weight.
Stopping it coming back
Provide plenty of light and prune the plant annually to maintain a compact shape.
