Prepare a clean seedbed or containers with fertile, moist, well-drained soil. Sow in spring as soon as soil can be worked, then in successions during cool weather. Sow about 3 mm deep and barely cover the seed unless the packet gives a more specific direction. Use the following spacing as the crop develops: 15 to 30 cm depending on type. Keep the medium evenly moist during emergence without leaving it saturated. Provide sun to partial shade and good air movement. Thin crowded seedlings early so the remaining plants develop without unnecessary competition. Harden indoor-started plants gradually before transplanting them outdoors after the appropriate frost date. Maintain even moisture and keep the seedbed cool.

Soil and care

Soil & care

Soil pH

6.0 to 7.0

Watering

Maintain even moisture and keep the seedbed cool. Check moisture at soil level instead of watering only by schedule. Water gently during germination so seeds are not displaced, then direct irrigation toward the root zone. Avoid standing water and adjust frequency after rain.

Soil type

‘Great Lakes 118’ lettuce performs best in fertile, moist, well-drained soil. Loosen compacted ground before sowing and remove large stones or persistent weeds. Mature compost may improve poor soil, but avoid creating a heavy or waterlogged seedbed.

Fertilization

Prepare the soil with mature compost when fertility is low. A light, balanced fertilizer may be used according to its label, but excessive feeding can cause weak or unbalanced growth. Observe leaf colour and plant development before adding more nutrients. Water after any application.

Seasonal care

At sowing time, prepare fertile, moist, well-drained soil and follow this timing: Sow in spring as soon as soil can be worked, then in successions during cool weather. Keep the surface moist until emergence, label the row, and thin seedlings according to the recommended spacing. During active growth, provide sun to partial shade and monitor soil moisture, weeds, and leaf condition. Maintain even moisture and keep the seedbed cool. In warm or windy weather, check containers and exposed beds more frequently. Remove damaged material and keep enough space for air circulation. At harvest or after flowering, use clean tools and clear unhealthy debris. Healthy residue may be composted where appropriate. At the end of the season, clean containers and tools, record useful observations, and store remaining seed in a cool, dry, dark place.

Container growing

A sufficiently wide container makes the leaves easy to reach.
