San Marzano tomatoes are a popular type of plum tomato that is famous for its sweet, rich flavor and meaty texture. These tomatoes originated from the town of San Marzano sul Sarno, located in the Campania region of Italy, and have become a staple ingredient in many Italian dishes, including pizza and pasta sauces. In this article, we will discuss how to grow San Marzano tomatoes, whether they are determinate or indeterminate, and everything else you need to know to grow these delicious tomatoes in your garden.

San Marzano Tomato Plant

The San Marzano tomato plant is a vigorous, determinate plant that typically grows to a height of around 6 feet. Unlike indeterminate plants that continue to grow and produce fruit throughout the growing season, determinate plants have a set size and produce most of their fruit at once. This makes them an excellent choice for gardeners who want a large harvest of tomatoes in a short amount of time.

The San Marzano tomato plant is relatively easy to grow and requires a warm, sunny location with well-draining soil. It is recommended to plant San Marzano tomato seedlings outdoors after the last frost date in your area. Before planting, prepare the soil by adding compost or well-rotted manure to improve soil fertility and drainage.

San Marzano Tomato

San Marzano tomatoes are typically oblong and have a deep red color when ripe. They are known for their meaty texture, low acidity, and sweet flavor, making them an excellent choice for sauces, soups, and stews. These tomatoes also contain a high amount of natural pectin, which makes them an excellent choice for canning and preserving.

San Marzano tomatoes are indeterminate, which means they will continue to grow and produce fruit throughout the growing season. This makes them an excellent choice for gardeners who want a continuous harvest of tomatoes. However, indeterminate tomatoes require more space and support than determinate tomatoes, so it is essential to provide them with adequate support as they grow.

Grow San Marzano Tomatoes

If you are interested in growing San Marzano tomatoes, here are some tips to help you get started:

1. Start with high-quality seedlings – Look for seedlings that are healthy, disease-free, and have a strong stem and root system.
2. Choose a sunny location – San Marzano tomatoes require at least 6-8 hours of direct sunlight each day to grow and produce fruit.
3. Provide support – Indeterminate San Marzano tomatoes require support to prevent them from falling over as they grow. You can use cages, stakes, or trellises to provide support.
4. Water regularly – San Marzano tomatoes require regular watering to keep the soil moist but not waterlogged. Water deeply once or twice a week, depending on the weather.
5. Fertilize regularly – Use a balanced fertilizer to provide the San Marzano tomato plant with the nutrients it needs to grow and produce fruit. Follow the instructions on the fertilizer label for the best results.
6. Prune as needed – Indeterminate San Marzano tomatoes may require pruning to prevent them from becoming too bushy and to improve air circulation around the plant. Remove suckers and any branches that are not producing fruit.

Harvesting San Marzano Tomatoes

San Marzano tomatoes typically take around 75-80 days to mature from seedling to fruit. As the tomatoes ripen, they will turn a deep red color and become slightly soft to the touch. Pick the tomatoes when they are fully ripe for the best flavor and texture.

San Marzano tomatoes are an excellent choice for canning and preserving. To preserve San Marzano tomatoes, blanch them in boiling water for 30 seconds, then peel off the skin and remove the seeds. Pack the tomatoes into sterilized jars, leaving 1/2 inch of headspace. Add lemon juice or citric acid to each jar to help preserve the tomatoes, then process the jars in a water bath canner for the recommended time based on your altitude.
