Sowing The Seed
Sorrel is a perennial herb that can be sown indoors or directly outdoors. If sown indoors, sow in peat pots, 2 to 4 weeks prior to the last frost. Place the seeds at a shallow depth of roughly 1/16" under topsoil so that light can still reach the seeds. Transplant or direct sow outdoors when temperatures are cooler but all danger of frost has passed.
Sorrel enjoys temperatures of roughly 68F or above. Again, since this herb does better in cooler temperatures, keeping the plants in full sun in cooler climates is recommended. Place in partial shade in warmer climates. The soil should be filled with organic matter and should also be well drained as well. Adding compost to hard, compacted soil can improve drainage. Water daily until seeds germinate.
Germination & Growth
Your Sorrel herb seeds will begin to sprout open within roughly 7 to 14 days or so. The plants themselves will reach a mature height of about 18 to 24 inches tall and can spread up to 18 inches wide. Their deeply established root system can be tricky to get rid of if you only want to grow as an annual, so growing them in pots is best. The leaves can be enjoyed when small or at full size.
