How to Grow Endives UK | Regional Planting Calendar

In the UK, endives go in the ground early March to mid August, and are ready to harvest 70–100 days after planting.
Endives (Cichorium endivia) — biennial.
Timing is the decision that matters most in the UK: there are 4 separate regional sowing windows, ranging from early March in Southern England to early March in Scotland.
Core growing advice on this page is checked against named horticultural and university-extension sources — see References.
NC State Extension: sow in early spring for harvest into early summer, and again in mid-to-late summer for an autumn/winter crop; a single window is applied uniformly across all four sub-regions since the source gives no UK-region-specific gradient.

NC State Extension: sow in early spring for harvest into early summer, and again in mid-to-late summer for an autumn/winter crop; a single window is applied uniformly across all four sub-regions since the source gives no UK-region-specific gradient.
Sow after frost risk has passed, in early spring for a summer crop or mid/late summer for an autumn-winter crop in cooler climates (NC State Extension).
Rosette leaf growth
1
Rapid rosette growth in full sun to partial shade, moisture-retentive well-drained soil; optimal growth at 60-65F, more heat-tolerant than lettuce but prone to bolting in short days or cool weather (NC State Extension).
Blanching (optional)
4
Hearts are often covered to exclude light for the last week or two before harvest, softening bitterness and paling the leaf colour.
Harvest
8
Harvest the loose rosette head about 70-100 days from sowing, before the plant bolts and runs to its pale blue summer flowers (NC State Extension).
When to pick: RHS: whole heads ready "about three months after sowing" (approx. 90 days); cut-and-come-again baby leaves ready "a month or so after sowing." NC State: overall growth period about 70-100 days. Harvest by cutting the stem and removing tough outer leaves; heads may be blanched by covering for 10-14 days to reduce bitterness before cutting.
Storage
Best used fresh; blanching improves flavour/texture before harvest
The most important oomycete disease of endive/escarole (Bremia lactucae): yellow-to-brown sunken angular leaf spots restricted by leaf veins, fuzzy white growth on the leaf underside, older outer leaves most affected,…

Frequently Asked Questions
When should I sow endives in the UK?
In Southern England, from early March. In Scotland, wait until early March. 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 endives?
Sow early March to mid August, at around 15°C for germination.
How long do endives take to grow?
Typically 70–100 days, depending on cultivar and growing conditions.
What soil pH do endives need?
A pH of about 6.5–7.8. 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 endives?
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.
