Harmony Butterhead Lettuce is our most improved butterhead variety with an excellent disease-resistance package. This variety is known for its production of large, well-formed heads that are dense and make solid weight. Heads are consistently uniform with velvety-smooth leaves that have a glossy, eye-catching appearance. Harmony Butterhead Lettuce is resistant to downy mildew, lettuce mosaic virus, and is less susceptible to tipburn. It is also slow to bolt and holds well in the field for longer harvesting windows. This is one of the best-tasting lettuce varieties you can grow. Use it to make exquisite salads or as a lettuce wrap with your favorite chicken or seafood preparation. Pair with a red butterhead for a colorful mix of lettuce greens.
Harmony Butterhead 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. Harmony Butterhead 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 20-20-2o 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.
