"Most vegetable gardens can accommodate winter crops. Some vegetables, such as Brussels sprouts, take up a lot of space for a long time but are still well-worth the investment. Choose an open site with free-draining soil, cultivated thoroughly prior to sowing or planting and enriched with organic material. Where ground is in short supply, containers will support a few plants. If a greenhouse or poly tunnel is available, it can be used to over-winter some crops and start others off early.
What to grow for winter:
Broccoli, Brussels sprouts, cabbages, kale, leeks and parsnips are hardy vegetables and will stand through the winter. Leafy crops such as chard, parsley and rocket should also over-winter with a little protection. Other crops such as carrots, onions, turnips and winter squash can also be grown to enjoy in winter if stored correctly"
