Recommended sowing period: in spring, as soon as the soil is drained and workable; adjust subsequent sowings to the season and type of harvest. The depth to respect is 0.2 to 0.5 cm (0.1 to 0.2 in). Germination usually takes 7 to 14 days. For germination, maintain the potting soil at 10 to 18 °C (50 to 64 °F). Sow few seeds at a time and renew sowings rather than preparing the entire crop in one day. Very hot periods can complicate lettuce emergence.
These 'Parris Island Cos' romaine lettuces form upright leaves around a crisp heart. Maintain regular moisture and harvest before prolonged heat accelerates bolting. Organize small successive plantings to have leaves at different stages. Lettuces can precede a warm-season crop or follow an early harvest. Combine several colors in well-identified rows, which facilitates selective harvesting. A close pass allows you to cut the leaves with a clean tool without walking on the bed. In the vegetable garden, it forms large, regular, elongated heads, with dark green leaves enveloping a pale, refreshing heart, highly sought after for summer harvests.

Growing method
Recommended sowing period: in spring, as soon as the soil is drained and workable; adjust subsequent sowings to the season and type of harvest. The depth should be 0.2 to 0.5 cm (0.1 to 0.2 in). Germination usually takes 7 to 14 days. For germination, maintain the potting soil at 10 to 18 °C (50 to 64 °F). Sow few seeds at a time and renew sowings rather than preparing the entire harvest in a single day. Very hot periods can make lettuce emergence difficult. Keep the potting soil cool, in the light, and transplant young plants without burying the heart. A seedling already crowded in its cell should be installed quickly to resume its growth. Harvest the outer leaves or the entire head depending on the type of lettuce. Avoid damaging the heart if you are waiting for new leaves. A central stem that lengthens indicates bolting and often a more pronounced bitterness. Enjoy the leaves before this stage, then replace the plant with a new sowing if the season permits. Leafy vegetables require a harvest adjusted to the type of plant.
Soil and care
The right care,at the right time.
Care level
Regular during establishment, then adapted to growing conditions
Watering
Regular
Soil type
Prepare soft, fertile, well-drained soil. Sow few seeds at a time and renew sowings rather than preparing the entire crop in a single day. Very hot periods can complicate lettuce germination. Keep the potting mix fresh, in the light, and transplant young plants without burying the heart. A seedling already crowded in its cell should be planted quickly to resume its growth.
Fertilization
Fertilization supports growth and takes into account the nutrients already present in the soil or potting mix. Use mature compost or a fertilizer suitable for the crop, following the dosage instructions. Avoid using multiple products, especially in a container where roots occupy a limited volume. Water as needed after application and observe leaf development before re-fertilizing.
Moisture
Keep the soil moist during germination, avoiding standing water; then adjust according to the crop.

Recommended pot size
A stable container with drainage holes, wide enough for the plant to spread out, and deep enough for the roots
Choose this exposure: sun to partial shade. Allow this spacing around the plant: 20 to 25 cm (8 to 10 in.). Lettuces appreciate a container that is easy to water and accessible from the kitchen. Roots should not sit in a saucer full of water. During hot weather, a location that receives less sun in the afternoon can help keep the soil fresh. Do not crowd adult plants: their leaves should be able to spread out without forming a damp mass.
