Carbon, Heirloom Tomato Seeds

Carbon, Heirloom Tomato Seeds — The Black Heirloom That Outperforms Every Other Dark Tomato

Carbon is the black heirloom tomato that delivers on every promise. Highly productive and remarkably practical, Carbon resists cracking and cat-facing better than other large black heirlooms — producing more marketable, beautiful fruit with less frustration. Blocky-round, 8–12 oz fruits arrive with dark-olive shoulders fading into a very dark, brick red exterior, with the rich flavor and meaty texture of a classic black tomato. Excellent yields and fruit quality for an heirloom, productive over a more extended period than similar types, with a well-balanced plant habit that makes it one of the most reliable black tomatoes available.

Excellent for salads and sandwiches. Indeterminate, open-pollinated, 75–80 days from transplanting.

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 dark and give slightly to gentle pressure.
