Cherry Roma (Solanum lycopersicum) is an indeterminate, open-pollinated tomato variety that produces abundant small, plum-shaped fruits approximately 1 inch long with a distinctive sweet and spicy flavor. Introduced to the Seed Savers Exchange in 1999, this variety displays resistance to fusarium and verticillium wilts, making it reliable for home gardeners. Seeds germinate rapidly within 5-10 days when maintained at optimal warm soil temperatures (75-85°F / 24-29°C) with consistent moisture.

Tips
Use a seed-starting heat mat to maintain soil temperatures of 75-85°F for optimal germination speed and uniformity. Keep soil consistently moist but not waterlogged; use a propagator dome or clear plastic cover to maintain humidity during germination. Once seedlings emerge, immediately remove the cover and provide bright, direct light (14-16 hours daily) to prevent weak, leggy growth. Water from below rather than overhead to reduce fungal disease risk. Sow seeds indoors 4-6 weeks before the last frost date. When seedlings develop their first true leaves, transplant into larger containers (3-4 inches), burying stems deep to promote stronger root systems. Harden off seedlings for 1-2 weeks in full sun before final transplanting outdoors after all frost danger passes.
