- Look for nearby trees or buildings casting shade.
- Inspect the branches for signs of weak or spindly growth.
Likely causes
Insufficient Light
Most likelyHow to tell: The branches are long, thin, and stretched out with large gaps between the leaves. The tree looks sparse rather than full and bushy.
What to do: Move the tree to a location that receives full sun for at least 6 to 8 hours a day. If it is planted in the ground, consider pruning back nearby branches that are blocking the light.
Lack of Pruning
PossibleHow to tell: The tree has many old, unproductive branches that make the overall shape look thin and straggly. New growth is weak and concentrated only at the very tips.
What to do: Prune the tree in late winter while it is dormant to encourage denser growth. Remove dead or crossing branches to allow light to reach the inner parts of the canopy.

When to worry
If the tree is losing its structural integrity or snapping in the wind, it is time to intervene. It is normal for the tree to look a bit thinner in the winter months.
Stopping it coming back
Plant your willow in a full sun location and prune it annually to maintain a strong, compact shape.

Questions people ask
- Will pruning make my willow bushier?
- Yes, pruning stimulates new growth from the nodes, which helps the tree fill out. Always use sharp, clean shears.
- Does my willow need fertilizer?
- Willows are fast growers and usually do not need much fertilizer. A light application of balanced fertilizer in early spring is plenty.
