Direct sow - early varieties Mar-Jun for summer harvests, maincrop Jul to mid-Aug for autumn roots. The earliest Feb sowings need cloche or greenhouse protection, and turnip tops can also be cut for spring greens in Mar-Apr.

UK timing runs on the last-frost date, not a USDA zone. Most of Britain sees its last frost around mid-May, with the north and exposed inland gardens a week or two later and the mild south-west and coast earlier. Tender crops start under cover and only go out once frost has passed; hardy crops can be direct-sown as soon as the soil is workable.

Timing aligned with the RHS grow-your-own guide for turnips.
