How to Grow
How to Grow Chinese Celery UK | Soil, pH & Growing Guide
Move through the SoilCommander growing library like a course: keep the navigation in place, open the next lesson, and build your garden plan step by step.
Water: Full sun or partial shade (RHS), and PFAF suggests some shade in summer, which suits a leaf crop being cut repeatedly. Keep the soil consistently moist. PFAF gives an optimal mean temperature of 16-21C; leaf growth is poor above that, so the plant is at its best in spring and autumn rather than the height of summer.
Soil pH range
6.66.8
Span reflects genuine variation between the cited authorities, not a single agreed figure.
A rich, light, moist soil. RHS lists loam and sand as suitable; PFAF adds that it tolerates mildly acid through to mildly alkaline conditions and will grow in very acid and very alkaline soils, though it prefers pH 6.6-6.8.
Drainage
Moist but well drained. The one thing it will not forgive is drying out.
Lifecycle
Biennial, grown as an annual for its leaves and cut repeatedly through the season.
PFAF sows this crop surface-sown in a greenhouse in February and continues as late as mid-April, which is the window recorded here. Two details matter more than the date. The seed needs light, so it is scattered on the surface and not covered. And germination is slow and erratic, taking two to three weeks at 15C, so a tray that looks empty after a fortnight has usually not failed. RHS rates the crop H6, hardy throughout the UK, so plants set out in spring will stand well into autumn and often through a mild winter.
Surface sow from February under glass and do not cover the seed, which needs light to germinate. PFAF gives two to three weeks at 15C, and warns that germination is erratic. Water from below so the seed is not washed off the surface.
Pricking out and growing on
Slow to start. Prick out into modules and grow on under cover until the weather settles, keeping the compost consistently moist.
Planting out
Set plants about 15cm apart in rich, moist soil in sun or light shade. No trench and no earthing up: this crop is not blanched.
Cutting season
Begin taking outer stalks once the clump is established and keep cutting. Growth is best at a mean 16-21C, so expect the strongest flushes in late spring and again in autumn rather than in high summer.
Second-year flowering
As a biennial it runs up to flower in its second June to August and sets seed in August and September. The leaves coarsen at that point, but the seed is itself a useful flavouring if you want it.
When to pick: Cut and come again rather than one harvest. Take the outer stalks at the base once the clump is established and leave the centre to keep growing; done that way a plant crops for months. The flavour is considerably stronger than stick celery, so a little goes further than you expect. In its second year the plant runs up to flower between June and August, and the leaves coarsen once it does.
Storage
Use fresh, or freeze chopped leaves. The stalks do not keep like blanched celery and are better left on the plant until needed.
Named by the RHS among the problems of this crop. Worth knowing that a related fungus carries a handling risk too: PFAF records that where plants are infected with Sclerotinia sclerotiorum, skin contact with the sap…
Named by the RHS among the problems of this crop. A young clump being cut repeatedly is soft, low and permanently damp, which is exactly what they want.
Slugs
moderate
Gastropoda (slugs, various spp.)
Named by the RHS among the problems of this crop, alongside snails.
Celery leaf miner (celery fly)
high
Euleia heraclei
Named by the RHS as a pest of this crop. The larvae mine blisters through the leaf, which matters more here than on stick celery because the leaf is the crop.
PFAF surface-sows in February under glass. Germination is erratic and takes two to three weeks at 15C, so a tray that looks empty after a fortnight has usually not failed.
As a biennial it flowers June to August and sets seed in August and September. The leaves coarsen then, though the seed is a useful flavouring in its own right.

Frequently Asked Questions
When do I sow chinese celery?
Sow early February to mid April, at around 15°C for germination.

Our data links 1 disease and 3 pests to this crop. See the sections above for each one and how to manage it.
Plan next season before the problems start
Most of the advice on this page comes down to timing and spacing — sowing at the right moment, rotating beds, and giving plants enough airflow. The UK Garden Planner lays your plot out month by month so those decisions are already made before the season starts.
