Sowing and Growing
Sow sorrel seeds indoors in early spring. Germination takes about 2 weeks. Transplant in mid to late spring. Space plants 12 to 15 inches apart and water generously. This herb grows best in full sun, but a partially shaded environment helps it deal with the heat. Not a beautiful plant and looking a bit weedy, cut back flower stalks to promote new growth. Sorrel does well in a container 6 to 12 inches deep and is ideal to grow as a cool season annual as the young leaves have the best flavor.
Harvesting
Harvest young leaves from established plants and use fresh for the best flavor. The tangy citrus flavor fades as older leaves become bitter, so harvest often to keep new growth coming. Well known for its use in soup, it is also great with fish and vegetables. With its strong yet agreeable flavor it makes a great secret ingredient to add depth of flavor to salads.
