Hi, New2! Official companionHi, New2! Official companion plants for lettuce are asparagus, beets, brussels sprouts, cabbage, carrots, corn, cucumbers, eggplant, onions, peas, potatoes, radishes, spinach, strawberries, sunflowers, and tomatoes. Broccoli is a no-no. The trick to keeping bugs off lettuce is to plant something nearby that will attract insect predators, such as ladybugs and parasitic wasps, that will eat bugs such as aphids. Toward that end, think about dill, parsley, marigolds, nasturtiums, and cosmos. You're in your salad days of gardening ... good for you!
