Romaine Lettuce

Romaine develops upright heads with elongated leaves and crisp midribs. Mini and full-sized cultivars have different spacing needs.

Tips

Space full heads about 10–12 inches apart.
Keep water steady as hearts develop.
Select locally adapted heat-tolerant varieties for late spring.
Cut before the center stretches into a flower stalk.
Sow seeds about 1/8 inch deep in cool weather and thin leaf types to 6-8 inches or heading types to 10-12 inches.
Keep the shallow root zone evenly moist with gentle watering rather than allowing it to dry out.
Apply a light nitrogen side-dressing if growth is pale or slow and soil fertility is low.
Check beneath leaves for slugs and remove them or use an iron-phosphate bait labeled for vegetables.
Harvest outer leaves above the crown, or cut heads before a tall flower stalk develops.
