YOUR SIMPLE GROWING PLAN
A garden bed. Here’s the plan.
A sunny, permanent garden bed. Start with bare-root division.
Allow at least 2 ft from the plant center to the bed edge. Choose a place it can stay.
Buy ‘Krinkled White’ with 3–5 visible buds, often called eyes.
- 01
Choose a lasting spot
Leave 4 ft between centers. Peonies dislike being moved repeatedly and need winter chill.
- 02
Place the eyes shallowly
Arrange roots in a roomy hole with eyes pointing up. Set the eyes about 1 inch below the final settled soil level; never bury them more than 2 inches deep.
- 03
Backfill gently and water
Settle the garden soil around the roots and water. Recheck the eyes’ depth after the soil settles.
- 04
Keep the crown clear
Do not pile mulch over the eyes. Mark the spot so you can protect the emerging shoots next spring.
Another way to start
Start with a potted peony in spring+
Buy the same cultivar as a nursery plant. Check where its eyes/crown sit rather than blindly burying the entire nursery surface deeper. Keep the eyes shallow, with drainage and the same eventual spacing.
Divide an established peony+
If division is needed, do it in fall and keep at least 3 healthy eyes per division. Do not divide routinely just to improve flowering; healthy clumps can stay in place for years.
When to water.
Check weekly during the first growing season, and sooner in hot dry weather. If the root-zone soil is drying, water slowly and deeply, aiming to moisten soil about 12 inches down. Wait when rain has already kept it moist. The goal is deep moisture without a waterlogged crown, not a fixed number of watering days. Established peonies usually need supplemental water only in prolonged drought, especially while buds develop.
Exactly what to feed it.
Skip added fertilizer in reasonably fertile soil. If growth stays weak, check planting depth, sun, and drainage before blaming nutrients. Use a soil test for an actual deficiency.
THE SIMPLE FEEDING PLAN
Start without extra fertilizer.
No routine fertilizer purchase for this starting plan. Do not try to force flowers with extra nitrogen or an acidifying fertilizer. If a soil test calls for nutrients, follow its specific rate and keep fertilizer off the crown.
A little patience pays off.
‘Krinkled White’ has single white flowers with golden centers, often in late spring or early summer. A mature plant is about 32 inches tall and 3 ft wide and may bloom for roughly two weeks. A new division can take 2–3 years to give a strong display.
When should I start where I live?+
Plant bare roots in early fall while soil is workable. Herbaceous peonies generally suit USDA zones 3–8, with cultivar and local climate differences. A mild winter without enough chill can limit flowering.

Something looking off?
It has leaves but no flowers. What went wrong?+
A young plant may simply need time. Also check eyes buried too deeply, too much shade, or excessive nitrogen. More fertilizer is not the default fix.
Do the ants help flowers open?+
Peony buds can attract ants, but flowers do not need ants to open. Their presence alone is not a reason to spray.
Buds turned dark and moldy.+
Cool wet conditions can favor botrytis. Remove affected material, improve airflow, and avoid wetting foliage. Local Extension can help distinguish disease from frost or other bud damage.
A little more growing know-how.
A lighter flower to start with+
The single flowers of ‘Krinkled White’ are less top-heavy than many double peonies. A hoop can still help in an exposed site; place it early so shoots grow through.
After the flowers finish+
Remove spent flower heads but leave healthy foliage to feed the roots. After a hard freeze, cut back dead stems and remove the debris. Do not leave diseased foliage around the crown.
