Days to Emerge: 5–14 days
Seed Depth: Surface to ⅛"
Seed Spacing: Broadcast about ½" apart
Thinning: Not required for baby greens
Harvesting: Harvest leaves with scissors 2" above the soil surface. Mesclun will regrow and provide 2–3 harvests, although the first harvest is usually the best. If you wish to harvest mature heads, cut off at 2" above ground level as soon as possible after head forms; new leaves will grow form the center. The earlier the harvest, the more tender the crop.
