Also known as beefsteak tomatoes, this group of tomatoes produces medium to large fruits that are often sliced for topping burgers and sandwiches, and is one of the top 10 must-grow plants. Often red but also available in yellow and green varieties, slicers tend to be disease-resistant and easy to grow. Some of the most popular slicers include 'Better Boy' and 'Celebrity'. Several heirloom tomatoes are also excellent slicers. 'Brandywine' is a pink-skin heirloom with soft flesh and full flavor. Get started with transplants from your local nursery or a mail-order source.
