Sorrels are very hardy greens that can be grown in almost every area of the United States. Sorrels require a sunny location with well-drained fertile soil.
Plant sorrels from seed two to three weeks before the average date of last frost. Plant the seeds 1/2 inch deep. When the plants are 6 to 8 weeks old, thin them to 12 to 18 inches apart.
Sorrel plants should be kept moist; water them more often than the rest of the garden.
Pick the fresh leaves of sorrel throughout the growing season. Pick off flowers before they mature to keep the plant producing new leaves long into the fall.
Types of Sorrel
Garden sorrel and French sorrel are sold under their common names. From seed to maturity is about 100 days.
