About Cotinus coggygria 'Golden Spirit'

Cotinus coggygria 'Ancot' (Golden Spirit) · also called Golden Spirit smoke bush, gold-leaf smoke bush · flowering

'Golden Spirit' is the gold-leaved smoke bush, holding luminous lime-yellow foliage all summer that warms to coral, orange and red in autumn. Airy summer flower plumes add a smoky haze. It needs full sun for the brightest colour but benefits from shelter from scorching midday heat, on free-draining soil of any reasonable pH.

Mature size: 3-4 m tall and 3-4 m wide (10-13 ft) unpruned; easily kept to 1.5 m with annual pruning.

Watch for — Leaf scorch: Brown, crispy leaf margins from intense midday sun or drought. Give some afternoon shade in hot regions and keep the roots cool with mulch and adequate moisture.

How to tell cotinus coggygria 'golden spirit' needs repotting

Repotting on a calendar is less reliable than reading the plant. For cotinus coggygria 'golden spirit', watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for cotinus coggygria 'golden spirit') flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to 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 cotinus coggygria 'golden spirit'

Only every 2–4 years, when genuinely crowded. Cotinus coggygria 'Golden Spirit' is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Rounded, bushy, multi-stemmed deciduous shrub; responds well to coppicing or hard spring pruning, which yields larger, even brighter leaves at the cost of flowers..

What size pot to step cotinus coggygria 'golden spirit' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Cotinus coggygria 'Golden Spirit' positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping cotinus coggygria 'golden spirit' into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

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 cotinus coggygria 'golden spirit'

Early spring, just as new growth restarts, is the ideal window for cotinus coggygria 'golden spirit'. 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 cotinus coggygria 'golden spirit'

Confirm it actually needs it. Slide cotinus coggygria 'golden spirit' out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip cotinus coggygria 'golden spirit' out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh free-draining, moderately fertile soil; tolerates chalk, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water cotinus coggygria 'golden spirit' again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for cotinus coggygria 'golden spirit'

Cotinus coggygria 'Golden Spirit' wants free-draining, moderately fertile soil; tolerates chalk. Happy on most well-drained soils across a broad pH range including alkaline chalk. Avoid waterlogged ground, which causes root rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting cotinus coggygria 'golden spirit' — frequently asked questions

How often should you repot cotinus coggygria 'golden spirit'?

Only every 2–4 years, when genuinely crowded for cotinus coggygria 'golden spirit'. Only repot cotinus coggygria 'golden spirit' every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using free-draining, moderately fertile soil; tolerates chalk. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does cotinus coggygria 'golden spirit' need?

When is the best time of year to repot cotinus coggygria 'golden spirit'?

Does cotinus coggygria 'golden spirit' like to be root-bound?

Yes — cotinus coggygria 'golden spirit' genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise cotinus coggygria 'golden spirit' after repotting?

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