Does fertilizer help with flowering?

Too much nitrogen fertilizer can actually encourage leafy growth at the expense of flowers. Use a balanced fertilizer once in early spring if your soil is poor.

Can I prune in winter?

Avoid winter pruning because you will cut off all the flower buds. Only remove dead or damaged wood during the winter months.

Likely causes

Improper Pruning
Most likely
How to tell: The shrub looks healthy but has no buds. You likely pruned it in late summer or fall, removing next year's flower buds.
What to do: Prune your Weigela immediately after it finishes blooming in late spring. Avoid cutting back the branches once summer starts so the plant has time to set new buds for the following year.
Insufficient Sunlight
Most likely
How to tell: The plant is growing in a very shady spot. It may look thin or stretched out.
What to do: Move your shrub to a location that receives at least 6 hours of direct sunlight daily. If moving is not possible, consider thinning out nearby tree branches to let more light reach the leaves.

When to worry

If the plant is young, it may take 2 to 3 years to reach maturity and produce a heavy bloom. Worry if a mature plant has had zero flowers for two consecutive seasons.

Stopping it coming back

Always prune right after the flowers fade and ensure the shrub is planted in a sunny spot.
