About Dogwood 'Eddie's White Wonder'

Cornus 'Eddie's White Wonder' · also called Eddie's White Wonder dogwood · flowering

'Eddie's White Wonder' is a hybrid flowering dogwood (Cornus nuttallii × florida) and holder of the RHS Award of Garden Merit. In late spring it smothers itself in large, rounded, pure-white bracts, followed by red berries and rich autumn leaf colour. More vigorous and free-flowering than either parent, it makes an outstanding small specimen tree for a sheltered spot.

Mature size: 5-8 m tall and 3-5 m wide (16-26 ft), eventually a graceful small tree.

How to tell dogwood 'eddie's white wonder' needs repotting

Repotting on a calendar is less reliable than reading the plant. For dogwood 'eddie's white wonder', 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 dogwood 'eddie's white wonder' 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 dogwood 'eddie's white wonder'

Every 2–3 years; top-dress in the in-between years. Dogwood 'Eddie's White Wonder''s growth habit — vigorous, upright-then-spreading small deciduous tree, more conical and faster-growing in youth than cornus florida, broadening to a rounded crown with age. — sets the pace. 'Eddie's White Wonder' is a hybrid flowering dogwood (Cornus nuttallii × florida) and holder of the RHS Award of Garden Merit. In late spring it smothers itself in large, rounded, pure-white bracts, followed by red berries and rich autumn leaf colour.

What size pot to step dogwood 'eddie's white wonder' up to

Move up exactly one pot size. A heavy dogwood 'eddie's white wonder' 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 dogwood 'eddie's white wonder'

Early spring, just as new growth restarts, is the ideal window for dogwood 'eddie's white wonder'. 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 dogwood 'eddie's white wonder'

Consider top-dressing first. If dogwood 'eddie's white wonder' 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 moist, fertile, humus-rich, slightly acidic well-drained soil 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 dogwood 'eddie's white wonder' in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave dogwood 'eddie's white wonder' 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 dogwood 'eddie's white wonder'

Dogwood 'Eddie's White Wonder' wants moist, fertile, humus-rich, slightly acidic well-drained soil. Prefers neutral to slightly acidic, organically rich soil with good drainage. It dislikes shallow chalk and heavy waterlogged ground. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting dogwood 'eddie's white wonder' — frequently asked questions

How often should you repot dogwood 'eddie's white wonder'?

Every 2–3 years; top-dress in the in-between years for dogwood 'eddie's white wonder'. Fully repot dogwood 'eddie's white wonder' 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 moist, fertile, humus-rich, slightly acidic well-drained soil. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does dogwood 'eddie's white wonder' need?

When is the best time of year to repot dogwood 'eddie's white wonder'?

Should you top-dress or fully repot dogwood 'eddie's white wonder'?

For a big, heavy dogwood 'eddie's white wonder', 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 dogwood 'eddie's white wonder' after repotting?

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