Muir Lettuce

Muir Lettuce has dense heads with light green broad wavy leaves. The heads are small in size and can be harvested as baby lettuce or grow into larger full-size heads. Its small size makes it a great option for hydroponic gardens! Muir lettuce has great heat tolerance and is resistant to bolting, making it a great variety for southern gardeners. 

Muir Lettuce performs best when transplanted. Transplanting allows for more consistent plant spacing and prevents seedlings from competing with weeds in the early stages of the plant. We recommend starting transplants 3-4 weeks before the desired outdoor planting date. These Seeds are pelleted for easy singulation when planting in seed trays. Muir transplants grow great in our heavy-duty seed starting trays, where they develop a solid root ball with roots that are trained to grow downward. Lettuce transplants will need adequate fertilization once seedlings form the first set of true leaves. We recommend injecting 20-20-20 through the seedling watering system at least once a week to ensure plants are sufficiently fed. This can be done easily with our Brass Siphon Mixer and a five gallon bucket. Plants are ready to go in the ground when they can be easily pulled from the cells in the seed starting tray.
