About Clematis 'Ville de Lyon'

Clematis 'Ville de Lyon' · also called Ville de Lyon clematis, carmine clematis · flowering

Clematis 'Ville de Lyon' is a vigorous deciduous climber with glowing carmine-red flowers darker at the edges, set off by yellow anthers from midsummer to autumn. A Pruning Group 3 hybrid, it flowers on new wood, so cut it back hard in late winter. Shade the roots and let the top growth climb into full sun.

Mature size: 3-4 m tall with a spread of around 1 m; vigorous yet manageable on most supports.

Watch for — Dry, hot roots: Drought and overheated roots reduce flowering and stress the plant. Mulch generously and keep the root zone shaded and evenly moist.

How to tell clematis 'ville de lyon' needs repotting

Repotting on a calendar is less reliable than reading the plant. For clematis 'ville de lyon', 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 clematis 'ville de lyon') 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 clematis 'ville de lyon'

Only every 2–4 years, when genuinely crowded. Clematis 'Ville de Lyon' 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. Vigorous deciduous twining climber clinging by leaf stalks. Bushy and very free-flowering on the current season's growth, ideal for walls, fences, trellis and scrambling through larger shrubs..

What size pot to step clematis 'ville de lyon' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Clematis 'Ville de Lyon' 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 clematis 'ville de lyon' 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.

The best time of year to repot clematis 'ville de lyon'

Early spring, just as new growth restarts, is the ideal window for clematis 'ville de lyon'. 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 clematis 'ville de lyon'

Confirm it actually needs it. Slide clematis 'ville de lyon' 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 clematis 'ville de lyon' 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 fertile, moisture-retentive well-drained loam, neutral to slightly alkaline, 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 clematis 'ville de lyon' 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 clematis 'ville de lyon'

Clematis 'Ville de Lyon' wants fertile, moisture-retentive well-drained loam, neutral to slightly alkaline. Improve with compost and plant the crown 5-8 cm deep to insure against wilt. Free drainage at the roots is essential while keeping consistent moisture. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting clematis 'ville de lyon' — frequently asked questions

How often should you repot clematis 'ville de lyon'?

Only every 2–4 years, when genuinely crowded for clematis 'ville de lyon'. Only repot clematis 'ville de lyon' 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 fertile, moisture-retentive well-drained loam, neutral to slightly alkaline. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does clematis 'ville de lyon' need?

When is the best time of year to repot clematis 'ville de lyon'?

Does clematis 'ville de lyon' like to be root-bound?

Yes — clematis 'ville de lyon' 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 clematis 'ville de lyon' after repotting?

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