Burgandy Boston Lettuce

Start seeds indoors 4-6 weeks before your last spring frost. Sow seeds directly on moist seed-starting soil at a depth of 1/4 inch, keeping the medium between 60-70°F for germination. Seeds typically sprout within 7-10 days. Transplant seedlings into larger containers once they develop their first true leaves, maintaining consistent moisture.

Harden off seedlings over 7-10 days by gradually exposing them to outdoor conditions. Transplant outdoors when soil temperature reaches at least 50°F and the seedlings have developed 4-6 true leaves. Space plants 8 inches apart in rows spaced 18 inches apart. Plant in early spring or late summer for the best results; timing allows the lettuce to mature during cooler weather when plants are less likely to bolt.

Direct sow seeds outdoors in early spring as soon as soil can be worked, or in late summer 8-10 weeks before the first fall frost. Scatter seeds on moist soil and press gently into place at a depth of 1/4 inch. Keep the seedbed consistently moist until germination occurs.

Harvest when the head feels firm and compact, typically around 50-55 days after sowing. You can harvest individual outer leaves once the plant is established, or wait for the entire head to form and cut it at ground level. For the full butterhead experience, harvest in the morning when leaves are crisp and cool. The head is ready when it reaches 5-10 inches in diameter and the outer burgundy leaves feel tender but substantial.
