Check these first
- Observe how many hours of light the tree receives daily.
- Check for nearby plants that might be shading it out.
- Look for signs of new growth at the tips of the branches.
Likely causes
Insufficient light
PossibleHow to tell: The branches stretch out long and thin with large gaps between the leaves. The tree looks sparse and reaches toward the nearest light source.
What to do: Move the tree to a location with more bright, indirect light. If it is in deep shade, prune back some of the surrounding canopy to allow more light to reach the branches. Do this gradually to avoid sunscald on the bark.
Improper pruning
PossibleHow to tell: The tree has long, bare branches that lack interior foliage. This often happens if the outer tips are pruned too heavily while the center is ignored.
What to do: Focus on light, selective pruning to encourage branching closer to the trunk. Remove only a small portion of the branch tips during the dormant season. This helps the tree fill out and look more balanced.

When to worry
It is normal for a young tree to look a bit sparse as it establishes its structure. Worry only if the tree stops producing new growth or looks weak and spindly.
Stopping it coming back
Provide the right amount of light from the start and prune lightly to maintain a healthy shape. Consistent care helps the tree grow dense and strong.

Questions people ask
- Will pruning make it grow back thicker?
- Yes, light pruning stimulates the tree to grow new shoots from the buds below the cut. Just be careful not to remove too much at once.
- Can I move my tree to a sunnier spot?
- Yes, but do it in the early spring or late autumn when the tree is dormant. Acclimate it slowly to the new light levels to prevent leaf burn.
