Apium graveolens var. dulce
Thirsty plant that loves a deep boggy pot — sweetened by self-blanching.

Allium
Leek
Leek's onion-family sulfur compounds repel celery leaf tier moths while both tolerate partial shade.
Brassica
Cabbage
Celery attracts hoverflies whose larvae consume cabbage aphids and small caterpillars.
Vegetable
Tomato
Tomato's height shades celery's shallow roots from heat stress; celery repels spider mites threatening tomatoes.
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 5 cm root end of a bunch. Stand in 1 cm of water; refresh every 2 days. New centre leaves in 5–7 days. Pot in compost after 2 weeks.
What to expect
A small clump of stalky leaves — never a supermarket-sized head.
Honest note
Honest verdict: looks like 'regrowing celery' on Pinterest, in real life is a sad stumpy clump. Mostly grown for the joke.
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.
