Red Horizon, Heirloom Tomato Seeds

Red Horizon, Heirloom Tomato Seeds — The Southern Russian Beefsteak That Resists Everything

Also known as Sunset’s Red Horizon, this remarkable heirloom beefsteak-type tomato originates from Rostov in southern Russia — a provenance that explains its extraordinary resilience. Red Horizon plants resist frost, blossom end rot, and cracking — three of the most common frustrations in the tomato garden — while producing huge, strong-flavored, heart-shaped fruits measuring 4–6 inches with thin skin and meaty, dense flesh. As an indeterminate plant, it continues producing until the first frost of autumn, giving you a long, generous harvest from a variety built to endure.

72 days from transplant. A tomato with genuine Old World toughness and exceptional flavor.

Why Grow Red Horizon?

Growing Notes

Start indoors 6–8 weeks before last frost. Sow seeds ¼ inch deep in fertile, well-draining soil. Transplant outdoors after all frost danger has passed, spacing plants 24–36 inches apart in full sun. Stake or cage vines. Water consistently. Harvest when fruits are fully red and give slightly to gentle pressure.
