Sow thinly during late spring and throughout the summer. Harvest the bright green citric leaves for use in salads or cook lightly like spinach. Sow in April outdoors in a light rich soil and a sunny location.
Seed can be started between February and July. Sow seeds in pots 1cm (½”) 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 (2″) container. Plants can be placed outdoors in late spring and will eventually need a 30cm (12″) wide pot filled with soil-based compost. Sorrel is ready to harvest when the leaves are about 4 inches long. Tender leaves are best for eating and if you harvest as cut-and-come-again, you will have a steady supply of young, tender leaves.
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.
