Marshall Lettuce grows with an upright habit that makes it easy to manage in confined spaces, requiring just 1 inch between plants and 16 inches between rows. The tight spacing and relatively quick 65-day maturity window mean you can succession plant every 2 to 3 weeks for a continuous supply of fresh leaves throughout the growing season. Its preference for moderate moisture and full sun, combined with straightforward care requirements, makes this a reliable workhorse for home gardeners seeking dependable leaf production.
Marshall Lettuce, as a romaine type, is used fresh in salads where its upright growth habit makes harvesting individual outer leaves practical. The leaf-by-leaf harvest method extends the plant's productive season, allowing you to gather tender outer leaves while the inner growth continues developing. This approach works well for mixed green salads or anywhere you want a continuous supply of fresh lettuce without replanting.

Start Marshall Lettuce indoors 4 to 6 weeks before your anticipated transplant date.
Transplant seedlings outdoors once they have developed 2 to 3 true leaves. Space romaine types 12 to 16 inches apart.
Direct sow seeds and use row cover to improve germination and prevent soil crusting. As soon as 2 to 3 true leaves have formed, thin to spacing requirements.
Harvest Marshall Lettuce by removing individual outer leaves once they reach usable size, allowing the inner leaves to continue growing and extending your harvest window. You can also cut the entire plant about 1 inch above the soil line for a single larger harvest, or remove it completely. Check plants daily as they approach maturity around 65 days, watching for leaves that are ready to pick; all varieties eventually become bitter as they begin to bolt, so timely harvest matters. For maximum productivity, practice leaf-by-leaf picking on the outer growth while the plant continues to develop inner leaves.
