San Marzano Tomato

San Marzano Tomato (Solanum lycopersicum) – 4–5 Inch Pot
Available in Jupiter, FL. at Urban Abundance.

A classic for a reason—the San Marzano Tomato is the gold standard for rich, flavorful paste tomatoes. Beloved by chefs and home cooks alike, this heirloom variety from Italy produces long, slender fruits with dense flesh, low moisture, and a signature sweet-acid balance. Part of the Solanaceae family, it’s considered a warm-season fruiting annual vegetable.

Grown in a 4–5 inch pot, our San Marzano starts are ready for transplanting into raised beds, large containers, or in-ground rows. With proper care, expect a steady stream of plum tomatoes perfect for sauces, canning, and roasting.

Sunlight Needs: Full sun—at least 6–8 hours daily is ideal for fruit set and flavor.
Watering Needs: Moderate. Keep soil consistently moist, not soggy. Drip irrigation or watering at the base is best to prevent leaf diseases.
Soil Requirements: Rich, well-drained soil with added compost. San Marzanos love fertile, slightly acidic soil (pH 6.0–6.8).
Growth Habit: Indeterminate vine—will continue growing and producing throughout the season. Requires staking, cages, or trellising.
Fruit Timing: Produces elongated, paste-style tomatoes 70–85 days after transplant. Harvest when fruit is fully red and firm.
Cold Tolerance: Not frost-hardy. Best grown during the South Florida cool season (October–March).
Special Features:

• Dense, meaty fruit with minimal seeds—ideal for cooking

• Classic Italian heirloom flavor

• High-yielding with regular feeding and pruning

• Performs well in raised beds and large pots with support

South Florida Notes: San Marzano grows beautifully during our winter season when humidity is lower and tomato diseases are less aggressive. For best results, space plants well for airflow, feed regularly, and prune bottom leaves to reduce fungal pressure.
