  • Planting: place seedlings 8"-10" apart in rows 18"-24" apart, in full sun or partial shade, in well-draining soil rich in nutrients and organic matter (can be amended with compost and/or worm castings before planting).

    Watering: keep soil evenly moist to avoid stunting growth or intense bitterness. 

    Harvesting: harvest at any stage of growth - baby leaves for salads and sandwiches, or large, mature leaves for pickling, juicing, or cooking.  In fall, harvest after a light frost as this improves flavor. Avoid harvesting leaves after the plant flowers, but you can harvest the flowers and use them in salads when this happens.
