Does fertilizer help it bloom?

Too much fertilizer can actually hurt flowering by encouraging leaf growth instead of blooms. A light layer of compost in the spring is usually all it needs.

Can I prune it in the fall?

It is better to wait until after it blooms. Fall pruning can remove the buds that are waiting to open in the spring.

Why is my Japanese Spirea not blooming? Causes and fixes

Check these first

Count how many hours of direct sun the plant gets each day.
Check when you last pruned the shrub.
Look for any overhanging trees that might be shading it.

Likely causes

Lack of sunlight
Most likely
How to tell: The plant looks healthy and green but has no flower buds. It may also look a bit stretched out or leggy as it reaches for more light.
What to do: Move the plant to a spot that gets at least 6 hours of direct sun. If you cannot move it, trim back overhanging tree branches to let more light reach the shrub.
Improper pruning
Possible
How to tell: You pruned the plant hard in the late spring or early summer, and now there are no flowers. You likely cut off the new shoots and their buds before they had a chance to open.
What to do: Wait until immediately after the plant finishes blooming to prune it next year. This gives the plant plenty of time to set new buds for the following season.

When to worry

It is only a problem if the plant has been in the same spot for years and suddenly stops blooming. If it is a young plant, it might just need another season to get established.

Stopping it coming back

Plant your Spirea in a sunny location and prune it only right after it finishes its spring or summer bloom. This ensures you never accidentally cut off next year's flowers.
