Scotland runs a shorter season than anywhere else in the UK matrix, and broad beans feel that more than most vegetables do. The Highlands and Northern Isles can still see frost into June; only the mildest coastal pockets — Argyll, Dumfries and Galloway — get close to the overwintering conditions the rest of the UK takes for granted.
Spring sowing is the default across almost all of Scotland — from March once the soil's workable, into April for later starts in the north. Autumn sowing only really makes sense in the mildest coastal spots: parts of Argyll, Dumfries and Galloway, and sheltered gardens near the Solway coast. Everywhere else, an autumn sowing is more likely to be killed by a hard frost than to give you a useful head start.
Overwintering in Scotland is the exception, not the rule. It's worth trying only if you're in one of the genuinely mild coastal pockets and can offer real shelter — a walled garden, a south-facing slope, something breaking the wind. For the Central Belt, the east coast, and anywhere upland, spring sowing isn't the cautious choice, it's simply the correct one.
Sow direct outdoors from March in the Central Belt and milder coastal areas, pushing into April further north or at altitude. If starting indoors to get ahead of a short season, module-raise from February and harden off before planting out once the worst frost risk has passed. Space plants 20cm apart in double rows — airflow matters more here than in milder parts of the UK, since damp, cool summers can make blackfly and fungal problems worse if plants are crowded.
Choose the sunniest, most sheltered spot available — in a short season, every extra hour of light and warmth counts. Sow 5cm deep, stake as plants grow, and pinch out the tips once pods start forming. Keep an eye on soil moisture through the summer; a cool, damp Scottish summer rarely needs much watering, but a dry spell inland can still catch plants out.
Yes, right across the country, but the growing plan looks different from the rest of the UK. Spring sowing and a fast-maturing, hardy variety matter more here than anywhere else in this series — the short season is the challenge to plan around, not the cold on any single night.
We trial our varieties on our own plot in Wales, which runs a much longer and milder season than most of Scotland. That gap is exactly why we'd steer Scottish growers toward spring sowing as the default rather than the fallback — what reads as a safe autumn sowing on our plot would be a real gamble across most of Scotland's shorter season.

Only reliably in the mildest coastal areas, such as parts of Argyll or Dumfries and Galloway, and even then a sheltered site helps a lot. Across most of Scotland, spring sowing gives far more consistent results than trying to overwinter.
Witkiem Manita, which matures quickly enough to make the most of Scotland's shorter window between last and first frost. The Sutton is a good second choice on exposed or windy sites.
Yes — the Highlands can see frost into June, weeks later than the Central Belt, and the growing season overall is shorter. Highland gardeners should sow later and lean even harder on fast-maturing varieties than growers further south in Scotland.
