Check these first
- Ensure the plant is receiving at least 6 hours of bright light.
- Check if the plant is crowded in its pot.
- Verify that you are not over fertilizing with high nitrogen, which promotes leaves over flowers.
Likely causes
Insufficient Light
Most likelyHow to tell: The plant looks healthy but produces only leaves and no flower stalks.
What to do: Move your plant to a spot with more direct sun or bright indirect light. Agapanthus needs plenty of light to trigger blooming.
Pot Size
PossibleHow to tell: The plant has been repotted recently into a much larger container.
What to do: Agapanthus prefers to be root bound to flower well. If you recently moved it to a large pot, it will focus on root growth instead of blooming for a season or two.

When to worry
It is normal for young plants or recently divided plants to skip a year of flowering. If it has been more than 2 years without blooms, you should adjust the light or pot size.
Stopping it coming back
Keep the plant slightly root bound and ensure it gets consistent bright light throughout the growing season.

Questions people ask
- Should I fertilize to get more flowers?
- Use a balanced fertilizer in spring, but avoid high nitrogen formulas. Too much nitrogen will give you lush leaves but no flowers.
- Do I need to divide my Agapanthus?
- Only if the plant is so crowded that it is pushing itself out of the pot. Otherwise, they bloom best when they are quite snug.
