How to Grow Globe Artichokes UK | Regional Planting Calendar
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.
In the UK, globe artichokes go in the ground mid February to mid April.
Globe artichokes (Cynara scolymus) — perennial.
Timing is the decision that matters most in the UK: there are 4 separate regional sowing windows, ranging from mid February in Southern England to mid February in Scotland.
Core growing advice on this page is checked against named horticultural and university-extension sources — see References.
RHS: sow indoors late winter to mid-spring; a single window is applied uniformly across all four sub-regions since the source gives no UK-region-specific gradient, and plants are typically raised under cover before planting out regardless of region.

Sow indoors late winter to mid-spring, about 2cm deep in modular trays or small pots, or direct outdoors in spring once soil has warmed; transplant when plants have at least five large leaves and are about 30cm tall (RHS).
Planting out and first-year establishment
1
Plant out at 75-90cm spacing after the last frost, hardened off first; remove any developing flower stalks in the first year so the plant puts energy into establishing strong roots (RHS).
Overwintering and spring regrowth
3
Top growth dies back in autumn; young plants need thick mulch plus cloches or fleece in hard frosts, established plants benefit from covering the crown with spent foliage and straw/bracken/compost mulch, then re-sprout in spring (RHS).
Budding and harvest
8
From the second summer, harvest flower buds from June onwards at full size but still tightly closed, cutting with secateurs above a leaf joint; a mature plant can produce up to 12 buds a year (RHS).
When to pick: RHS: young flower stalks removed in the first summer; a full crop of buds is produced in the second summer, harvested June to September. Harvest "when the flower buds are still tightly closed", using secateurs, "before the bracts start to open" — check regularly as buds open quickly in warm weather. Cornell: most gardeners remove and eat the flower head and bracts before they open, harvesting the hearts before flowering.

Frequently Asked Questions
When should I sow globe artichokes in the UK?
In Southern England, from mid February. In Scotland, wait until mid February. Treat these as a guide rather than a fixed date — the governing rule is to sow only once frost risk has passed and temperatures are reliably warm enough.
When do I sow globe artichokes?
Sow mid February to mid April.
What soil pH do globe artichokes need?
A pH of about 6–6.5. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.
What problems affect globe artichokes?
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.
