How to Start Sorrel From Seed
Sorrel is a hardy perennial leafy herb with a tangy flavor and a long harvest season. Seed-grown plants establish easily, though named varieties may be more uniform when divided from established plants.
Start indoors or direct sow?
Start indoors and transplant for an earlier patch, or direct sow because sorrel tolerates cool soil and minor frost. It handles transplanting well while young, but direct sowing is simple for a permanent bed.
When to start Sorrel seeds
Start indoors 6 to 8 weeks before the last spring frost, or direct sow 2 to 3 weeks before it. You can also sow in late summer or early fall where seedlings have time to establish before hard winter weather.
How to sow the seeds
Sow seeds 1/4 inch deep in sterile seed-starting mix in cell packs or small pots. Keep the mix evenly moist, and use a bright window or grow light after seedlings emerge.
Germination
Sorrel generally germinates in 7 to 14 days. Soil temperatures around 60 to 70 F and consistent moisture encourage even sprouting.
Seedling care
Give seedlings bright light and water when the mix begins to dry, without leaving roots constantly saturated. Thin to one sturdy plant per cell, use clean containers, and provide airflow to prevent damping off.
Transplanting & hardening off
Harden seedlings off for 7 to 10 days, then transplant when they have several true leaves and the ground is workable. Space plants about 12 to 18 inches apart in a bed where they can remain for several years.
Tips
Remove flower stalks if you want the plant to focus on tender leaves. Divide established clumps every few years if plants become crowded or less productive.
