Can be transplanted or direct sown. Plant seeds in fertile, loose soil. Remember to keep the soil consistently moist. Thin down to final spacing once plants are established. For best results, plant in spring or fall. Harvest outside leaves for a continual harvest. For longer harvest, stagger planting every 2-3 weeks.
Sow 2-3 seeds 1/4" deep per cell and 2-3" apart in Organically composted, well-drained soil with a pH of 6.0-7.0. Seeds germinate in 3-10 days, transplanting or thinning back to 1 plant every 9-12" as leafy heads establish.

How to Harvest Lettuce
Most varieties of lettuce can be harvested 45-60 days after sowing or once the younger outer leaves have reached 4-5" long as a "cut and come again" crop. Harvest leaves when young and tender for best flavor since leaves bitter with maturity. Heads may be harvested whole, roots and all, or just be cut at the base while leaving behind an inch to the rooted stem. Garden fresh lettuce stores well cold in a plastic bag for 7-10 days. Do not store near apples or bananas.

Cultivated throughout the 19th century by pioneering American horticulturalist Eugene Davis, Grand Rapids lettuce was named for the hometown in which he began his commercial greenhouses; developing a perennial grow operation in which Grand Rapids lettuce, among other crops, was grown and shipped year-round from Michigan greenhouses.

Perfect for cold-frames, greenhouse growing or in the garden of course. Crisp, tend and tasty. Resistant to heat and tipburn resistant.

Also known as "feuille de chene" in France, oakleaf was sold in 1771 by the historic French seed producer Vilmorin, which had been King Louis Xv's personal seed supplier. Heads form large rosettes of uniform leaves that are heat resistant. Royal Oakleaf lettuce is an improved Oakleaf variety that is slower to bolt.
