Likely causes
Lack of direct sun
Most likelyHow to tell: The tree looks healthy but never produces flowers, or it is shaded by buildings or larger trees.
What to do: Ensure the tree receives full sun for at least 6 to 8 hours a day. If it is in a shaded spot, you may need to prune back surrounding branches.
Tree is too young
PossibleHow to tell: The tree is growing well but is still quite small.
What to do: Be patient, as young Jacarandas often take 5 to 10 years to reach maturity and start blooming.

When to worry
It is normal for young trees to take years to bloom. Only worry if the tree is mature and still shows no signs of flowers.
Stopping it coming back
Plant in a location with full, unobstructed sun and avoid heavy nitrogen fertilizers that encourage leaves over flowers.
