lamb's lettuce

Lamb's lettuce (Valerianella locusta) benefits from regular watering. Water when the soil is slightly dry—about once a week—during the growing season and every 2 weeks during the winter months. Water at the base of the plant, avoiding wetting the foliage to discourage disease. If growing indoors, use a watering can with a long spout to avoid wetting the foliage. For outdoor containers, the best way to water is by moistening the soil thoroughly with a slow trickle of water until it begins to drain from the bottom of the pot. Keep an eye on the moisture level of the soil and adjust the watering routine accordingly.

Lamb's lettuce is a cold season crop that is particularly well suited to growing in full sun. The plant does not tolerate summer heat well and should receive no more than 6-8 hours of direct sunlight a day, preferably during the cooler morning and early afternoon hours. The sweetest flavor is achieved when planted in locations with morning sun and afternoon shade. Too much sun will cause it to bolt quickly. It is recommended to mulch around the plants to help keep the soil cooler and retain moisture.

Lamb's lettuce (Valerianella locusta) should be pruned regularly to keep a good shape and vigor. Early in the season, lightly prune the foliage and flower stalks and remove any withered foliage. During the mid to late season, prune to keep it shapely and free of weeds. In late autumn, cut back any dead or damaged foliage and shape the plant to prepare for winter. When the weather warms up in the spring, prune lightly again to help encourage new growth.
