The San Marzano Tomato (Solanum lycopersicum) is prized for its deep red, glossy fruits measuring 2–2¼ inches long and weighing 1½–2 ounces, with each cluster producing an impressive 12–18 tomatoes. Known for its sweet, low‑acidity flavor, minimal seeds, and rich, intense tomato taste, this variety is ideal for salads, fresh salsa, and especially homemade pasta sauce. These vigorous indeterminate vines grow rapidly—often stretching 6–10 feet—and require sturdy support to handle their heavy fruit load. Plant in rich, well‑drained soil high in organic matter, spacing plants 24–36 inches apart, and choose a sunny location with 6+ hours of direct light to ensure strong growth and full color development. Maintain consistent moisture, as San Marzano thrives with steady watering and a soil pH of 6.0–6.8.
