A Comprehensive Guide to Growing San Marzano Tomatoes
Have you ever dreamed of picking juicy, fleshy tomatoes right from your garden to make the perfect sauce? Growing ‘San Marzano’ tomatoes at home in the US can make that dream a reality. Although we may not be able to perfectly replicate the terroir of this famed Italian plum variety, your homegrown harvest will still be delicious.
The Story of ‘San Marzano’ Tomatoes
First cultivated near Naples in Italy, ‘San Marzano’ tomatoes are known for their fleshy texture, easy-to-peel skin, and nearly seedless nature. These characteristics make them an excellent choice for creating flavorful sauces. The volcanic soil near Mount Vesuvius, where these tomatoes historically grow, gives them a unique taste that cannot be duplicated elsewhere.
In order to ensure authenticity, commercial production of ‘San Marzano’ tomatoes in Italy is regulated according to strict standards. When shopping for ‘San Marzano’ products, look for the Protected Designation of Origin (DOP) emblem. This certification guarantees that the tomatoes are grown in the designated region and meet quality standards.
While authentic ‘San Marzano’ tomatoes are hard to come by outside of Italy, home gardeners can still enjoy growing this delicious variety in their own backyard. Although they might not be the exact strain grown in Italy, homegrown ‘San Marzano’ tomatoes are perfect for cooking, canning, and sauces.

What Are San Marzano Tomatoes?
‘San Marzano’ tomatoes are oblong fruits with a distinctive shape and minimal seeds. While they are classified as paste tomatoes, they are not technically Roma tomatoes. Originating near Naples, Italy, this unique variety developed from Central and South American origins.
These tomatoes typically grow on indeterminate vines, producing clusters of six to eight fruits with a vibrant red color. Their firm flesh, thin skins, and minimal seeds make them ideal for cooking down into rich sauces.
How to Grow
How Many to Plant
When planning your garden, consider planting multiple ‘San Marzano’ tomato plants if you intend to make large quantities of sauce or preserve them. Each plant can produce around 10 pounds of fruit throughout the season, so plan accordingly.
Timing
Since ‘San Marzano’ tomatoes take longer to mature than other varieties, be sure to start seeds indoors early in the season to account for the extended growing period. Consider planting other faster-maturing varieties if you have a short growing season.
Support
Even shorter vine strains of ‘San Marzano’ tomatoes may require staking to support the weight of the fruit clusters. Use cages, stakes, or trellises to provide proper support for your plants.
Container Considerations
If growing in containers, make sure they are at least four to five gallons in size to sustain a ‘San Marzano’ tomato plant. Provide additional support for the vines in pots, as they will need extra care compared to plants in the ground.
Where to Buy
Purchase ‘San Marzano’ starts from local nurseries or buy seeds and plants online from reputable retailers. Consider different varieties, such as ‘San Marzano Redorta,’ which produces larger fruits, to experiment with different flavors.
Harvesting and Preserving
When harvesting ‘San Marzano’ tomatoes, pick them when they are ripe and use them fresh in recipes. You can also freeze or dehydrate them for later use. Experiment with sun-dried tomatoes or green tomato pickles for unique culinary creations.
Cooking Ideas
