Tender vegetables

These are damaged by frost. Start them under cover and plant out only once the risk of frost has passed in your own garden. Harden plants off over a week or so before they go outside.

"Sow / plant outdoors" is the transplant-out date where a crop is started indoors, otherwise the direct-sowing date. "Last sow for autumn" is the latest sensible sowing for a crop to mature before the first autumn frost.

Reading these dates

These are guides based on South West England's approximate average frost dates, not a forecast. Aspect, altitude, shelter and the weather in any given year can shift them by two weeks or more, so treat them as a starting point and adjust to your own plot. Sow a little later in a cold spring and keep horticultural fleece ready for a late frost.
