Start seeds inside at a temp of 68°. Water seed starting soil before sowing seeds. Seeds need light to germinate - sow seeds on soil surface and expose them to light (either artificial light or sunlight). Keep seeds moist until germination by watering them with a mist (a handheld sprayer works well for this). Cover seed flat with a dome to keep moisture in (but you should air it out 1x per day for 20 minutes to prevent fungal growth). Days to germination: 10-18. Transplant outside in early May. Or, you can sow seeds directly outside May 15th on the soil surface, keeping them moist until germination. Plants are hardy to zone 6.
Harvest leaves as desired. Plants contain high amounts of oxalic acid so only eat small quantities of Red Veined Sorrel.
Plants are wind pollinated. They can self-pollinate. Plants will not cross with other species of sorrel. Collect seeds July-Sept as they mature. Mature seeds will have turned from white/tan to red/brown.
