What's my last sowing date?

Pick a crop and the date you usually get your first autumn frost. You'll see the latest day you can sow it and still pick it in time, and, if you sow little and often, how many more sowings fit.

Your usual first autumn frost The date you usually expect the first frost where you grow. Enter it yourself, or look it up by postcode.

What this knows, and what it doesn't

  • How the date is found. For each remaining day this year, we ask the same question the Vercro Garden plan asks: if sown today, is this crop in its window, and will it be ready before the frost? The last sowing date is where the answer changes.
  • The frost date is yours to set. Enter it, or add your postcode and we fill in the date your area's first autumn air frost usually comes, from 30 years of Met Office records. It's a typical year: in about half of years the first frost comes earlier, and the look-up tells you how early it runs in 1 year in 10.
  • Sowing windows are national. Month by month, from Vercro's UK calendar, not shifted for where you live.
  • Late sowings are the least certain. Growing times are the catalogue's usual range. Shorter autumn days slow growth and that isn't modelled.
  • The interval is yours. The catalogue has no recommended gap between sowings for each crop, so we don't suggest one.
  • Under cover is a general figure. About 10% faster in a greenhouse and about 7% faster in a polytunnel, the same for every crop.
