Nothing beats a crisp and refreshing salad on a summer day, but growing lettuce during the heat of summer is always a challenge. See how tried-and-true varieties stack up against newcomers for production during summer. This trial included a mix of green Batavia and Romaine lettuce. Growers received a subset of 3 varieties, and are asked to plant at least 10 individuals of each variety in the same conditions, either by transplanting or by overseeding and thinning to 10 plants at standard head lettuce spacing (or 12″). Trial were planted the last spring or summer planting, or by July 10th.
