Nearly every list of easy-to-grow vegetables starts with lettuce, and with good reason: so long as you plant it at the right time, it will grow from seed with little attention.

The tomato industry has a long history in Arkansas and is particularly known in the northwestern and southeastern areas of the state. Tomatoes appeared early in the stateâs history. During the 1830s, Albert Pike, who owned the Arkansas Advocate newspaper, made the tomato the centerpiece of his campaign to expand food choices for the state. However, tomatoes were not grown on a large scale until commercial canning plants became common in the state.
