About Paris Market Carrot

Daucus carota 'Paris Market' · also called Paris Market Carrot, Parisian Carrot · edible

Paris Market is a compact, round-rooted carrot cultivar reaching only 2–3 cm diameter, ideal for shallow soils and container growing. Sow direct in loose, stone-free beds; thin to 5 cm apart. Needs consistent moisture for smooth roots. Matures in 60–70 days. Sweet, tender flesh makes it a favourite for snacking and market gardens.

Mature size: Root: 2–3 cm diameter, 3–4 cm deep; foliage height 20–30 cm

Watch for — Carrot root fly (Psila rosae): Larvae tunnel into roots, causing rusty scarring and rot. Use fine insect-mesh barriers from sowing; avoid crushing foliage (the smell attracts flies). Companion-plant with alliums or grow under fleece.

How to tell paris market carrot needs repotting

Repotting on a calendar is less reliable than reading the plant. For paris market carrot, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot paris market carrot on before it becomes hard root-bound.

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 paris market carrot

Pot on seedlings as they grow; not a perennial repot. Paris Market Carrotis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Annual taproot vegetable; upright ferny foliage 20–30 cm tall with a compact, globe-shaped root.

What size pot to step paris market carrot up to

Pot paris market carrot on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

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 paris market carrot

Pot paris market carrot on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting paris market carrot

Pot on before it is root-bound. Check paris market carrot regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh light, sandy loam or purpose-blended container compost at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water paris market carrot in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for paris market carrot

Paris Market Carrot wants light, sandy loam or purpose-blended container compost. Needs loose, stone-free, deeply dug soil with good drainage. Heavy clay or compacted soil causes misshapen roots. Ideal pH 6.0–6.8. Enrich with well-rotted compost but avoid fresh manure (causes forking). Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting paris market carrot — frequently asked questions

How often should you repot paris market carrot?

Pot on seedlings as they grow; not a perennial repot for paris market carrot. Paris Market Carrot is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into light, sandy loam or purpose-blended container compost so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does paris market carrot need?

When is the best time of year to repot paris market carrot?

Can you put paris market carrot straight into a much bigger pot?

No. Even a fast-growing paris market carrot should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise paris market carrot after repotting?

Not immediately. Wait about 1 week after repotting paris market carrot. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
