Lettuce plants are grown for their edible leaves that are most commonly used in salads. Plants will grow wonderfully if they full sun for cool-weather areas, and partial sun in warmer areas. Don’t allow the soil to dry out. Fertilize every three weeks. Leaf lettuce may be cut whenever it is large enough to use. Head lettuce should be harvested when the heads are firm and fully formed. All of our Lettuce Plants for sale are grown organically and shipped with very well-established root systems. We guarantee them to arrive alive and thriving.
