Carrots 
By regularly sowing suitable types you can have fresh carrots nearly all year round. Carrots can also be stored and frozen although, as with most veg, they are at their best when freshly picked.
Sow 13mm (0.5in) deep in rows 15cm (6in) apart. Sow thinly to avoid thinning out, or thin to 5-7.5cm (2-3in) apart.
Early cultivars can be sown as soon as February or March under cloches or similar protection, but the main sowing season is from April to early July.
Be careful when thinning out to avoid carrot rootfly - they are attracted by the smell released when the skin is bruised.
Keep the soil evenly moist to avoid splitting.
Keep weeds at bay as carrots can easily be swamped by them.
Harvest carrots as soon as they are large enough to use; don't aim for the largest roots or you'll sacrifice flavour.
Lift carefully using a fork if the soil is heavy.
