Likely causes
Tarnished Plant Bug
Most likelyHow to tell: The flower buds look stunted, distorted, or fail to open entirely. You may see small, mottled insects on the stems.
What to do: Remove and destroy damaged buds to stop the spread. Use insecticidal soap to treat the plant if you see active bugs.
Insufficient Light
PossibleHow to tell: The plant looks healthy and leafy but produces no flower spikes. It is likely growing in a spot that is too dark.
What to do: Move the plant to a location with bright, indirect light or dappled shade. Astilbes need some light to produce their signature plumes.

When to worry
If the plant is mature and healthy but consistently fails to bloom for two seasons, it needs a better spot. It is normal for very young plants to skip flowering their first year.
Stopping it coming back
Keep the plant healthy with consistent water and monitor for pests during the spring bud development.

Questions people ask
- Do astilbes need fertilizer to bloom?
- They do not need heavy feeding, but a light application of compost or balanced fertilizer in spring can support flower production. Do not overdo it, as too much nitrogen encourages leaves over flowers.
- How much light is enough for flowers?
- They bloom best in partial shade where they get a few hours of morning sun. Too much deep shade will prevent them from flowering.
