Hamson tomato is an open-pollinated, indeterminate slicing tomato that produces medium-sized fruits weighing 8-9 ounces with a distinctive scarlet-red color and uniform round shape. Bred for both traditional garden beds and protected growing environments, this variety matures in 70-79 days from transplant and thrives across hardiness zones 2-11 in full sun. Its combination of disease resistance, reliable production, and adaptability to various growing methods, from raised beds to greenhouses, makes it a dependable choice for gardeners seeking classic tomato flavor and appearance.

These scarlet-red globes develop with remarkable uniformity, making them as visually consistent as any commercial variety yet retaining the open-pollinated genetics that let you save seeds year after year. The plant grows indeterminate and can stretch 36-96 inches tall depending on your region and care, behaving as semi-determinate in longer growing seasons. Strong resistance to Bacterial Canker, Fusarium Wilt, Late Blight, Powdery Mildew, Tobacco Mosaic Virus, and Verticillium Wilt means you spend less time troubleshooting disease and more time harvesting.
These medium-sized slicing tomatoes are well suited to fresh eating, slicing for sandwiches and salads, and cooking applications where a dependable all-purpose tomato is needed. Their uniform size and consistent shape make them practical for both kitchen use and seed saving, allowing gardeners to maintain the variety across seasons.

Start seeds indoors 6-8 weeks before your last spring frost date. Sow seeds 1/4 inch deep in seed-starting mix and maintain soil temperature between 70-75°F for germination. Keep soil consistently moist but not waterlogged, and provide bright light once seedlings emerge.
Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days. Transplant outdoors after all danger of frost has passed and soil temperature reaches at least 60°F. Space plants 24 inches apart in rows spaced 36 inches wide.
Harvest when fruits reach full scarlet-red color and feel slightly soft to gentle pressure, typically 70-79 days after transplanting. Tomatoes picked at the breaker stage (when the first blush of color appears) will ripen indoors if needed. Twist or cut the fruit gently from the vine to avoid damaging the stem.
As an indeterminate variety, Hamson tomato benefits from regular pruning of suckers, the shoots that grow between the main stem and branches. Remove lower leaves once the plant is established to improve air circulation around the base and reduce disease pressure. In regions with longer growing seasons where the plant exhibits semi-determinate behavior, pruning can be more conservative to maintain fruiting branches.
