Planting Tips
- Choose the Right Season: Plant romaine lettuce in early spring or late summer for optimal growth. These cooler months allow for better leaf development.
- Select Quality Seeds: Choose high-quality romaine lettuce seeds from a reputable source. Varieties like ‘Paris Island’ or ‘Little Gem’ provide delicious results.
- Prepare the Soil: Use well-drained soil with a pH of 6.0 to 6.8. Incorporate organic matter for improved fertility.
- Sow Seeds Properly: Space seeds about ½ inch apart in rows that are 12-18 inches apart. Lightly cover with soil, ensuring not to bury them too deep.
- Water Frequently: Keep the soil consistently moist, especially during dry spells. Use a gentle spray to avoid disturbing the seeds.
- Identify the Right Time: Harvest romaine lettuce when the hearts are compact and firm—usually 70-80 days after planting. Look for vibrant green leaves.
- Use Proper Tools: Use a sharp knife to cut the base of the plant, about 1-2 inches above the soil line. This prevents damage to the surrounding soil.
- Harvest Entire Heads: For maximum flavor, consider harvesting the whole head. This ensures the entire heart can be enjoyed.

Storage and Freshness
To keep the heart of romaine lettuce fresh, follow these simple storage tips. Place it in a sealed plastic bag or an airtight container. This prevents moisture loss while protecting it from odors in the refrigerator.
Store your romaine lettuce at a temperature between 32°F and 36°F. This range helps maintain crispness and freshness. Do not wash the leaves until you’re ready to use them, as excess moisture can hasten decay.
Check freshness frequently. Look for any yellowing or wilting leaves. Remove any spoiled parts to extend the life of the remaining lettuce.
If you plan to use the heart within a week, it’s best to store it in the crisper drawer of your refrigerator. For longer storage, consider freezing the heart after blanching.
