Organic Parris Island Cos Romaine Lettuce Seeds

This brilliant green lettuce was developed in Israel and remains sweet even through the heat of summer. Mildew and disease resistant, it usually will not bolt and is valued for its crispness and flavor. Approx. 200 seeds. Non-GMO

Sowing: Lettuce grows well in cool weather, so the first crop can be direct sown when the soil temperature reaches at least 35 degrees F, or as soon as the soil can be worked. If the soil temperature rises above 75 degrees F, the seeds become dormant. Direct sow the seed in rich soil and full sun, spreading them as thinly as possible in rows 1-2' apart; when the seedlings begin to grow, thin them to a distance of 6-8". Succession crops can be grown for fresh lettuce all season in areas with cool summers or warm winters; this is accomplished by planting a new crop every 2 weeks. For companion planting benefits, grow lettuce with onions, cucumbers, or carrots.

Growing: Since lettuce has very shallow roots, it needs adequate moisture in order to stay tender and sweet; keep the soil evenly moist. Applying mulch helps conserve moisture and control weeds.
