Days to Maturity: Approximately 50-65 days from transplant to full head harvest (baby leaves ready in 30-45 days).
Sun Needs: Full sun to partial shade (4-6+ hours of direct sun ideal); in Utah’s hot summers, afternoon shade helps prevent bolting and keeps leaves tender.
Season Type: Cool-season crop; thrives in spring and fall—plant early (as soon as soil is workable, around 40°F+) or late summer for fall crops; tolerates light frosts but bolts in prolonged heat above 80°F.
Plant Habit & Support: Compact rosettes 8-12 inches tall and wide; no support needed—space 8-12 inches apart for full heads or closer (4-6 inches) for cut-and-come-again harvesting.
Other Notes: Excellent heat and bolt resistance for a butterhead; watch for aphids, slugs, or tip burn from inconsistent moisture—good airflow and organic mulch (like straw or compost) help prevent issues; ideal for succession planting every 2-3 weeks.
Best Planting Method: Transplant when soil is cool and workable in early spring or late summer for fall crops. Space plants 8-12 inches apart in rows or beds; plant at the same depth as in the pot. Amend soil with compost for fertility and excellent drainage—raised beds are beneficial in heavier or alkaline Utah soils to avoid waterlogging. Organic mulch (such as straw, compost, or grass clippings) around plants retains moisture, moderates soil temperature, and suppresses weeds.
Watering Needs: Maintain consistently moist soil (about 1-2 inches per week) without sogginess—even moisture is key to preventing bitterness, bolting, or tip burn; drip irrigation or careful base watering keeps foliage dry in dry Utah air. Mulch helps hold moisture during warmer spells; containers dry out faster, so check frequently.
Fertilization Needs: Incorporate compost or balanced organic fertilizer at planting for nutrient-rich soil. Lettuce is a light feeder—apply a light nitrogen-rich side-dressing (like compost tea or fish emulsion) midway if growth seems slow, but avoid excess to prevent soft, disease-prone leaves. Harvest outer leaves as needed for cut-and-come-again (encourages regrowth) or cut the whole head at the base when mature; regular picking keeps quality high and extends production before bolting. It's great for containers.
