About Prunus 'Accolade'

Prunus 'Accolade' · also called Accolade Cherry, Accolade Flowering Cherry · flowering

'Accolade' is an early-flowering ornamental cherry bearing abundant clusters of semi-double, soft-pink blossoms from late winter into early spring, opening from deeper pink buds. Its graceful, spreading branches and orange autumn tints give a long season of interest. A smaller, more elegant alternative to the heavier 'Kanzan', well suited to medium-sized temperate gardens.

Mature size: 6-8 m tall and 6-8 m wide at maturity.

Watch for — Rootstock suckers: Grafted trees may produce suckers from the rootstock around the base; remove them cleanly at the source as they appear to keep the tree's shape.

How to tell prunus 'accolade' needs repotting

Repotting on a calendar is less reliable than reading the plant. For prunus 'accolade', watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and prunus 'accolade' wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot prunus 'accolade'

Every 2–3 years; top-dress in the in-between years. Prunus 'Accolade''s growth habit — graceful deciduous tree with a rounded, spreading crown and gently arching branches; moderate growth rate, more refined and open than 'kanzan'. — sets the pace. 'Accolade' is an early-flowering ornamental cherry bearing abundant clusters of semi-double, soft-pink blossoms from late winter into early spring, opening from deeper pink buds. Its graceful, spreading branches and orange autumn tints give a long season of interest. A smaller, more elegant alternative to the heavier 'Kanzan', well suited to medium-sized temperate gardens.

What size pot to step prunus 'accolade' up to

Move up exactly one pot size. A heavy prunus 'accolade' dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot prunus 'accolade'

Early spring, just as new growth restarts, is the ideal window for prunus 'accolade'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting prunus 'accolade'

Consider top-dressing first. If prunus 'accolade' is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh fertile, moisture-retentive, well-drained loam beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave prunus 'accolade' in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave prunus 'accolade' in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for prunus 'accolade'

Prunus 'Accolade' wants fertile, moisture-retentive, well-drained loam. Adaptable across acidic to alkaline soils including chalk, provided drainage is good. Avoid wet, heavy clay, which invites root and crown disease; enrich poor soils with organic matter. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting prunus 'accolade' — frequently asked questions

How often should you repot prunus 'accolade'?

Every 2–3 years; top-dress in the in-between years for prunus 'accolade'. Fully repot prunus 'accolade' only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with fertile, moisture-retentive, well-drained loam. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does prunus 'accolade' need?

When is the best time of year to repot prunus 'accolade'?

Should you top-dress or fully repot prunus 'accolade'?

For a big, heavy prunus 'accolade', top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise prunus 'accolade' after repotting?

Not immediately. Wait about 4 weeks after repotting prunus 'accolade'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
