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.

Growth habit: 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 fertiliser clematis 'ville de lyon' actually wants — and why

Clematis 'Ville de Lyon' is a heavy-blooming flower with a big appetite — a regular high-potash feed through the season is what drives a long, dense display.

A high-potassium ("high-potash") flowering feed — tomato-style or a dedicated bloom/rose feed. Potassium powers flowering; a high-nitrogen feed gives you a leafy plant with disappointing bloom.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for clematis 'ville de lyon': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed clematis 'ville de lyon', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For clematis 'ville de lyon':

Apply a balanced fertiliser in early spring, then a high-potash feed such as tomato food every two to three weeks during budding and flowering. Mulch annually with compost or well-rotted manure to feed and cool the roots. For a hungry bloomer that means feeding regularly — sparingly through the growing season — right through flowering across the main season (spring through early autumn), tapering as blooming ends.

The dormant-season rule matters more than the exact interval: skip feeding entirely when clematis 'ville de lyon' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for clematis 'ville de lyon'

Follow the flowering-feed label rate for clematis 'ville de lyon', or half strength if feeding very frequently. These plants genuinely use the nutrients — under-feeding shows up fast as a thin display.

Feeding always goes onto already-damp soil, never dry roots — water clematis 'ville de lyon' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the clematis 'ville de lyon' watering schedule.

Signs you are over-feeding clematis 'ville de lyon'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for clematis 'ville de lyon':

Lots of lush leaves but few flowers (too much nitrogen).
Scorched leaf edges and salt crust from too-strong or too-frequent feeds.
Soft, sappy growth prone to aphids and mildew.

Signs you are under-feeding clematis 'ville de lyon'

Sparse, small, short-lived flowers and pale foliage.
A tired plant that stops blooming early in the season.
Weak growth and poor repeat-flowering after the first flush.

Flushing and leaching the salts

Organic options

A liquid comfrey or seaweed feed (naturally potassium-rich) plus compost or well-rotted manure as a mulch. UK: comfrey feed, organic Tomorite, or rose feed; US: Espoma Rose-tone or Neptune's Harvest. Feeds and improves soil.
