Onions Planting selected onion sets in autumn will give you a crop from late June into early July. Carrots Make good use of your cold frames during the winter by sowing a crop of 'Primo' carrots. Chives are a valuable garnish at any time of year for sprucing up a salad, adding flavour to potatoes and colouring winter soups. The challenge is to produce enough fresh leaves throughout the year. Easily raised from seed, chives can be sown in spring in any spare corner.
Flowers follow in summer, which can be picked for salads or left to form seed.
Lift and divide congested clumps that have lost vigour every few years. Small clumps can also be grown in pots on the windowsill. Keep some chives by the kitchen window for a tasty winter garnish.
