Great Lakes Lettuce produces medium to large heads with bright green leaves. It is a very crisp variety and slow to bolt in hot weather. An All-America Selections winner in 1944, this first true iceberg lettuce remains a favorite for both home gardens and restaurants alike. It tolerates light frost, is heat and cold tolerant and has a strong resistance to bolting and tip burn. This variety is perfect for adding to salads, sandwiches and burgers and has a good shelf life when refrigerated.
Growing Great Lakes Lettuce
For an early start, Great Lakes Lettuce Seeds can be started in flats 4 weeks prior to the last frost and transplanted outdoors in mid to late spring.
Sow seed 1/8 inch deep, 1 inch apart in rows 12 to 18 inches apart.
When plants have two or three true leaves, thin to 12-inch spacings for crisphead varieties, 6 to 10 inches for other types.
You can also lightly broadcast seed (particularly of looseleaf varieties) in a patch instead of a row.
Lettuce has a shallow root system. Keep soil moist to keep plants growing continuously. Mulch to retain moisture and suppress weeds.
Lettuce is tolerant of a wide range of soils, but prefers well-drained, cool, loose soil with plentiful moisture and pH 6.2 to 6.8.
