San Marzano

Tomato

75d to harvest

Sun-warmed and richly aromatic, San Marzano paste tomatoes ripen to a deep, velvety red with a firm, meaty interior and a pleasantly low-seed count. Their elongated, tapered shape holds its structure beautifully, delivering a dense, spoonable texture that’s ideal for thick sauces and slow-simmered favorites, as well as roasting for concentrated flavor. Grow these in cool-season confidence for a harvest that tastes unmistakably classic—bright, savory, and beautifully concentrated.

Frequently Asked Questions

What pest or disease most commonly affects Solanum lycopersicum (San Marzano tomato), and how do I manage it?

Early blight and Septoria leaf spot are common on tomatoes, showing up as dark spots with yellowing on lower leaves. Remove and discard infected lower foliage, improve airflow with wider spacing and stake/tie plants upright, and water at the soil line to keep leaves dry. If the problem spreads, spray a labeled tomato fungicide early (start when spots first appear) and repeat according to the label interval.

How often should I water San Marzano tomatoes during the main growing phase?

During active flowering and fruit set, keep soil evenly moist by watering deeply about 1–2 times per week, aiming for consistent moisture rather than daily light watering. Water when the top 1 inch of soil feels dry, and apply enough to soak the root zone (roughly 6–12 inches). Mulch after plants are established to reduce swings in moisture that can trigger blossom-end rot and cracking.
