Growing Instructions for Ultimate Salad Bowl:

Direct sow from 4 weeks before last spring frost until 2 weeks before first fall frost at 3-week intervals. Thin by harvesting (and eating!) half of the young plants, leaving half to mature further for additional harvests. Harvest promptly to avoid stressing plants through overcrowding.  For salad cuttings, cut when 3" high, about 3 weeks after seeding. Harvest the leaves only, leaving growing tip to regrow. Repeat 2 times. To create a decorative border for your garden, we recommend mixing USB seeds with sand in a 1:1 ratio and drizzling the mix along a shallow trough around your garden.
