UK Vegetable Planting Calendar (When to Sow, Plant Out and Harvest)

If you have ever stood in front of a packet of seeds wondering whether to sow them now or wait, this is the page for you. UK gardening is all about timing. Sow too early and seeds rot in cold soil. Plant out too late and crops do not have time to ripen before autumn. Get the timing right and most vegetables look after themselves.

This calendar covers the most popular UK vegetables across the whole year. Each colour shows what to do in each month. Light green for sowing indoors, dark green for sowing outside, blue for planting out, and orange for harvesting. Click on any crop name for the full month-by-month guide for that vegetable.

Timings are based on an average UK garden. Adjust by a couple of weeks earlier if you are in southern England or later if you are in Scotland or northern areas. If you are not sure when frost is finally past in your area, our UK Last Frost Dates by Postcode guide is a useful reference before you commit anything tender to the ground.

Want to grow flowers alongside your vegetables too? What Flowers to Plant in May in the UK covers easy hardy annuals like nasturtiums and cornflowers that work brilliantly between veg crops.
