A month-by-month seasonality chart for fruit, vegetables, herbs and foraged finds, with the peak weeks picked out, storage notes and a shopping list you can copy or print. Eating to the season is cheaper, tastes better and travels less β and this works with the wifi off.
The months are outdoor growing seasons for the UK and Ireland, which line up closely with the rest of northern Europe. North America uses the same months with a few shifts β sweetcorn and tomatoes run longer, okra and southern specialties appear that never grow here. Southern-hemisphere options simply move the whole calendar on six months, which is right for the big crops but rough at the edges for subtropical fruit.
Two limits to keep in mind. Storage stretches a season: apples, pears, onions, carrots, potatoes, squash and celeriac are harvested in autumn and sold for months afterwards, so "in season" and "on the shelf" are not the same thing β the notes say where that applies. And weather moves the edges: a cold spring or a wet summer shifts the first and last weeks of everything by two or three weeks either way.
Supermarkets stock most of this all year from glasshouses, cold stores and imports β this chart is about when it is at its best and best value where it grows, not a stock check. Nothing you type or tick here leaves your device.
