Harvesting, Curing & Optimal Storage
Harvesting can begin 4-6 weeks after planting once leaves are large enough for your culinary uses. Use sharp scissors to cut the cress about an inch above the base to encourage regrowth. For optimal storage, wash and dry leaves, then keep them in a damp paper towel within a plastic bag in the refrigerator for up to a week.
