Oak leaf lettuce was introduced in the 1770s and was known at that time as “American Oak Leaved”. Just like the name implies Oakleaf has deeply lobed leaves that form a tight cluster. The unique shape really adds to salads.
They provide a high dose of beta carotene, linked with cancer prevention particularly lung cancer and reduction in the risk of heart disease. Beta carotene is converted by the body into vitamin A, vitamin that prevents night blindness, needed for growth and cell development, maintains healthy skin, hair, and nails as well as gums, glands, bones, and teeth. May prevent lung cancer.
Sun: Full Sun
Optimum Soil ph: 6.2-6.8
Days To Maturity: 55-65 Days
Sowing Method: Directly Outdoors
Lettuce grows best in full sun, though excessive heat can cause plants to bolt to seed, or leaves to wilt. For an early start, seeds can be started in flats 4 weeks prior to the last frost and transplanted outdoors in mid to late spring. If growing in summer, select a partially shaded location, or one that receives primarily eastward exposure to mitigate the potentially damaging effects of excessive heat upon lettuce.
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. Sensitive to low pH. Lime to at least 6.0. To encourage tender and tasty growth, make sure location is rich in organic compost matter. Amend prior to planting if needed.
