Tomatoes are a summer favorite. When you get a really amazing tomato, you should consider saving its seeds for future planting seasons. Saving seeds at the end of a season’s harvest will help you save money, have stronger tomatoes and also save the stock of seeds for the future. “Our food system would be less stable if we were just relying on one or two varieties because they won’t have the resilience when disease and other pressures come along,” said Kate Garland, horticultural specialist at the University of Maine Cooperative Extension.
