Sorrel is easy to start from seed or you can save time and buy a ready-grown plant so you can start pick leaves immediately.
Seed can be started between February and July. Sow seeds in pots 1cm (1/2 in) deep and place in a light position to germinate. When large enough to handle, divide the rootball up and give individual seedlings their own 5cm (2in) container. Plants can be placed outdoors in late spring and will eventually need a 30cm (12in) wide pot filled with soil-based compost.
Grow in well-drained soil in a sunny or lightly shaded spot, or plant into the middle of a container filled with multi-purpose compost.
Water plants often, especially during warm, dry summers.
Nip out flowers to prevent plants running to seed.
Top growth of plants will die back in autumn. Raise pots up onto special pot feet or even bricks to allow excess moisture to drain away, reducing the risk of compost remaining soggy and roots rotting.
Divide established plants every couple of years in spring or autumn to rejuvenate congested clumps and to ensure plants are productive.
Pot grown plants can be planted out into well drained, moist soil in sun or partial shade.
Best used fresh, pick leaves by hand from spring to early autumn. Young leaves near the tips of shoots taste better than larger leaves lower down the stems.
