Heirloom Variety 30+ Seeds Non GMO All American lettuce of famous Bibb or Limestone type but tolerates hot weather and is slower to shoot seed stalks. Thick, deep green leaves are tender, sweet, crisp with that rare Bibb flavor. Packaged by Raleigh Seed Co. Ready for planting. ♥♥♥ PLANTING INSTRUCTIONS ♥♥♥ Start lettuce seeds indoors or out, by sprinkling seeds in rows or in containers, and covering with a layer of soil. If starting indoors, cover containers with a plastic bag to create a greenhouse effect and keep warm. Sprouts should appear within a week to 10 days. Once sprouted, remove the plastic and provide plenty of light. Once seedlings have a few sets of true leaves, transplant to individual containers. Harden off seedlings about a week before transplanting out of doors. In outdoor beds, either thin or place transplants to desired spacing. We recommend approximately 4 inches apart for leaf lettuce varieties, 8 inches apart for loose-head types, and 16 inches for firm-head types.
