- Check if nearby plants are shading your peony.
- Review your recent fertilizing habits.
Likely causes
Insufficient light
Most likelyHow to tell: The stems are thin, weak, and stretching toward the nearest light source. The plant produces fewer flowers than usual.
What to do: Move your peony to a spot that receives at least 6 to 8 hours of direct sunlight daily. If you cannot move it, prune back nearby trees or shrubs that might be casting too much shade.
Excessive nitrogen fertilizer
PossibleHow to tell: The foliage looks lush and green, but the stems are floppy and the plant fails to bloom. The growth is rapid but lacks structural strength.
What to do: Avoid high nitrogen fertilizers in the spring. Use a balanced fertilizer or one higher in phosphorus to encourage strong stems and blooms instead of just leafy growth.

When to worry
If the stems are so weak they cannot support the weight of the flowers, you should address the light levels. It is normal for young peonies to be a bit smaller in their first year.
Stopping it coming back
Provide full sun and avoid over fertilizing with nitrogen to keep growth sturdy.

Questions people ask
- Do peonies need full sun?
- Yes, peonies thrive in full sun to partial shade. They need at least 6 hours of direct sun to grow strong stems and produce plenty of flowers.
- Will my leggy peony ever bloom?
- If the legginess is caused by lack of light, it may struggle to bloom. Once you provide more sun, the plant should produce sturdier stems and better flowers in the following season.
