When to sow vegetables for winter harvests
Spring and summer
Sow hardy winter vegetables such as sprouting broccoli, Brussels sprouts, kale, winter cabbage and leeks in late spring or early summer as they take several months to reach maturity. They stand well through frosty weather and can be harvested throughout the winter months.
Sow leafy crops such as chard, chicory, landcress and parsley in early summer for autumn harvests that can last into winter if they are provided with some fleece or cloche protection.
Late summer and autumn
Sow corn salad, land cress and oriental salad leaves such as komatsuna, mibuna, mizuna, mustard and rocket. These will provide cut-and-come-again leaves through the autumn, and winter if covered with a cloche, coldframe or fleece.
Potatoes can be planted in mid- to late summer for winter harvests.
