History of San Marzano Tomatoes

San Marzano tomatoes originated near Naples, Italy, in the volcanic soils surrounding Mount Vesuvius.

Flavor Profile

Growth Type / Harvest Yields

Indeterminate – plants continue growing and producing throughout the season until frost. Expect abundant clusters of fruit over a long harvest window.

Disease Resistance

San Marzano tomatoes are valued for strong productivity but, like many heirlooms, benefit from preventative care. Good airflow, mulching, crop rotation, and consistent watering help reduce common tomato issues such as blight and cracking.

Growing Tips & Planting Dimensions

• Start with rich, well-drained soil amended with compost
• Plant in full sun (6–8+ hours daily)
• Space plants 24–36 inches apart
• Space rows 36–48 inches apart
• Install cages, stakes, or trellises early
• Water deeply and consistently
• Mulch to retain moisture and suppress weeds
• Prune lightly for airflow and easier harvesting

When to Start Indoors

Start seeds indoors 6–8 weeks before your last spring frost date. Transplant outdoors after danger of frost has passed and soil has warmed.
