Growing Lettuce

Cultivation: Plants are grown from seeds and often transplanted. Seedlings are transplanted after 30-35 days and spaced 45 cm apart. Seeds need to be sown very shallowly. In hot places lettuce develops a bitter taste if transplanted or checked in their growth. Cutting the tap root can stop plants seeding quickly.

Edible Uses: Eaten raw or in soups. The sprouted seeds can be used in salads or sandwiches. Leaves can be dried and stored. The leaves are used for sarma in Turkey. They are rolled around a filling of rice or minced meat.

Production: Leafy varieties are harvested after 50-60 days.
