Peonies are long-lived perennials, so it is
worth the effort to prepare the site well and purchase quality
plants. Peonies are one of the least demanding perennials giving
outstanding bloom and all season foliage on disease and pest
Soil: Peonies prefer a sunny well drained site. Dig a hole
larger that the root and amend the soil with compost or bonemeal.
Very well aged manure may be used in moderation. Peonies will not
survive in waterlogged soil.
Planting a) Herbaceous Peonies: Place the peony root in the
prepared hole and backfill. The crown buds should be no more than 2
inches below the soil surface. If planted too deep, they may not
flower for several years. Plant potted peonies at the same depth as
they are in the pots.
b) Intersectional (Itoh) Peonies are planted so the top eyes are
planted just below the surface and the buds on the root are about 2
inches below the surface.
c) Tree peonies will be shipped with tags indicating the correct
planting depth. They will be planted a few inches deeper than they
were previously since this will encourage more roots to develop on
the tree peony stems.
Watering: Peonies are drought tolerant but benefit from watering
during periods of prolonged dryness especially in the first growing
season. If you mulch your garden, do not put mulch over the crown.
After Flowering: When the peonies have finished
flowering, cut off the spent blooms but leave as much foliage as
possible to promote strong roots.
Winter Care: In September, herbaceous and intersectional peonies
are cut off close to the ground but the stems of tree peonies are
left since they are woody shrubs. Remove all types of peony foliage
from the garden to help prevent spread of any possible disease or
