Spring Onion
Muddles carrot fly with onion volatiles — classic combo.
Herb
Chives
Chives repel carrot rust fly and aphids while their onion scent masks carrot odor.
Leafy green
Lettuce
Lettuce's shallow roots don't compete with carrots' deeper growth, and leaf cover deters carrot rust fly larvae.
Root
Radish
Radish matures quickly, breaking soil for carrots, then harvests before competing; its rapid growth marks carrot rows.
Situations where this plant is a reliable fit — from someone's kitchen sill to a wind-blown rooftop.
Balcony
A few pots on a flat outdoor perch — some sun, some wind.
Grow bag
Cheap flexible bag, 20–40 L — hungry crops with big roots love these.
Reused bucket
A salvaged 10–20 L bucket with drainage holes — a proper productive pot for very little cost.
Raised bed
A traditional plot or timber-sided bed — deepest root run, widest planting choice.
Water jar
A jam jar of water on the sill — no soil at all. Regrow from kitchen scraps.

How to do it
Save the 2 cm top with the stem stub. Stand cut-side-down in 1 cm of water; new feathery leaves in 5 days. Pot in compost — but ONLY the leaves grow on, not a new root.
What to expect
Feathery edible carrot-tops for garnish or pesto. No new carrot will grow.
Honest note
Honest verdict: countless Pinterest posts pretend you can 'regrow carrots' — you cannot. The TOPS are useful though.
Where to source

Shop local first
The best plants come from a real nursery, and the best trowel comes from the old-fashioned ironmonger down the road — people who know their stock and can advise. Try local first, both for the plant and the kit. It keeps small growers and small hardware shops alive.
Searching near London
For pots, compost, seed trays, twine and other kit — Amazon has the essentials if the local option isn't right. Not a plant nursery; use the local map above for the plant itself.
