Coastal Star Romaine Lettuce is an open-pollinated romaine variety that produces full-sized heads of crisp, delicious lettuce. It produces dark green leaves and tall heads at maturity. Coastal Star may be harvested as leaf lettuce when plants are young, but can also be cut once for head production. It is relatively heat-tolerant and will perform well in late spring or early fall. This lettuce variety is great for planting in rows for a traditional, in-ground garden, but it also works well for container or raised bed gardening. Romaine lettuce performs well when planted densely, about 8-12″ apart. This will help to shade the surrounding soil and reduce weed growth. It will also allow you to grow a significant amount of food in a small space.
Coastal Star Romaine 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. Coastal Star 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.
