Planting Peony Bare Roots: Depth, Timing and First-Year Care

Peonies are sold as bare roots for a reason: the plants resent disturbance, and a dormant root lifted in autumn establishes faster than a potted plant that has spent the summer in a nursery. Plant it right once and it will outlive most of the shrubs around it.

When to plant

Plant bare-root peonies from late September to early November, while soil is still warm enough for roots to establish before it freezes. Spring planting works but sets the plant back a season. If your roots arrive and you cannot plant for a week, keep them in damp newspaper in a cool, dark place — not in water.

The one rule that decides whether you get flowers

Peony eyes — the pink buds on the crown — must sit no more than 1–2 inches below the soil surface. Plant too deep and you get a healthy leafy plant that never flowers, sometimes for years. Dig a wide hole, build a cone of soil, spread the roots over it, and set the crown so the highest eye is barely covered. Mulch around, never over, the crown.

Site and soil

• Sun: six hours minimum; more in cool climates, afternoon shade in hot ones.
• Drainage: essential. Peonies rot in wet feet, especially in winter.
• Spacing: 3 feet apart — they grow wider than you think and dislike being crowded.
• Depth: the hole should be twice as wide as the root spread, with compost and a handful of bone meal worked into the base.

The first two years

Do not expect a full display immediately. A new bare root may produce one or two flowers in year one, more in year two, and its real performance from year three. Remove the first year’s buds if you want the plant to build size instead — painful advice, but it works.

Ants on peony buds

Ants are not damaging the buds; they are collecting the sugary sap the bud exudes. Leave them alone. If you cut buds for the house, shake them out or dunk the stems in water before bringing them inside. Washing the ants off does the plant no harm, and the old myth that peonies need ants to open is exactly that — a myth.

Support and aftercare

Herbaceous peonies flop in rain. A peony ring or three stakes with twine, installed when shoots are a foot tall, saves the display. Cut foliage to the ground in late autumn after it blackens; this reduces overwintering disease. Feed once in early spring with a low-nitrogen fertiliser — too much nitrogen gives leaves at the expense of flowers.
