Likely causes
Lack of Sunlight
Most likelyHow to tell: The tree looks healthy and green but produces no flower buds. This happens if the tree is shaded by buildings or larger trees.
What to do: Move the tree to a spot that gets at least 6 to 8 hours of direct sun. If you cannot move it, prune back surrounding trees to let more light reach the canopy.
Improper Pruning
Most likelyHow to tell: You pruned the tree in the late spring or summer, cutting off the new growth where flowers form. Crape myrtles bloom on new wood.
What to do: Stop pruning during the growing season. Only prune in late winter while the tree is dormant, and avoid topping the tree, which ruins its natural shape and flowering potential.

When to worry
If the tree is in full sun and you have not pruned it incorrectly, it might just be too young to bloom. Be patient, as some varieties take a few years to mature.
Stopping it coming back
Plant your Crape myrtle in a sunny, open location and only prune it lightly during the winter months.

Questions people ask
- Does topping the tree stop it from blooming?
- Yes, topping removes the growth tips where flowers develop. It also creates weak, spindly branches that are prone to breaking.
- Can I fertilize to help it bloom?
- Too much nitrogen fertilizer can actually encourage leaves at the expense of flowers. Use a balanced fertilizer sparingly in early spring if the soil is poor.
