|'Redcurl' is a green Romaine lettuce with red highlights, which is generally ready for harvest 30 days after sowing. It is an excellent garnish lettuce, and is a fast grower in both hot and cool weather, making it a good through-season cultivar. Start from seed 4 to 6 weeks before average last frost date. Sow seeds 1/4 inch deep in wide rows and thin to 8 to 12 inches apart. Thinned seedlings can be replanted. Keep soil moist but not soggy. Protect from rabbits and slugs. Extend the harvest season by planting successive crops. Summer heat causes lettuce to bolt. Pick outer leaves as they grow or harvest all at once. Harvesting when weather or day temperature is cooler will result in crisper leaves. Do not harvest lettuces until you are ready to use it.
