Frequently Asked Questions
Why won't my peonies bloom?
- Planted too deep: If the eyes are more than two inches underground, lift and replant.
- Small divisions: When very small divisions are planted flowers take longer to appear. Divisions with 3-5 eyes will reach blooming size more quickly than the much smaller 2-3 eye divisions often sold in garden centres.
- Too young, or moved and divided too often: Allow the plant more time to develop; it should be in the same spot for at least five years.
- Large clumps transplanted without proper division: Divide (3 -5 eyes per division) and replant.
Undernourished: Buds form but don’t develop. Top dress with compost, avoiding the crown of the plant. Peonies will not flourish if soil is poor or competition from nearby shrubs and trees.
- Over fertilized: Plants have deep green foliage but form no buds. Water thoroughly to was away excess nitrogen and cut down on fertilizer.
- Too much shade: Plants will be tall and lanky; replant in full sun(6 or more hours) or part shade(4 to 6 hours). An hour or two less won’t make much difference but heavy partial shade will reduce the likelihood of flowers.
- Not enough moisture: Water to bottom of roots. (Established plants will bloom even when severely drought-stressed, although not profusely.
- Root competition from neighboring trees or shrubs: Replant outside the neighbour’s root zone.
- Buds develop but fail to open: These may be damaged by late frost, disease, drought, or being waterlogged.
- Root system undermined by gophers or moles: Put in a wire mesh barrier around the bed.

My tree peony has grown new stems which have produced different looking leaves and blooms from the original plant. What has happened, and what should I do about it?
Why do the buds on my peony sometimes turn black and dry up early in the season?
Some garden centres and retail stores sell potted peonies in the spring. I have read that the best time to plant peonies is in the fall. Can potted peonies be planted in spring or must they be kept in the pot until the fall? Are there any special instructions if planted early?
