Proven Winners® Proven Selections® San Marzano Heirloom Tomato Bush

The San Marzano Heirloom Tomato Bush is prized for its rich, sweet flavor and meaty, elongated tomatoes. With fewer seeds and less water content than many other tomato varieties, San Marzano tomatoes are perfect for making thick, flavorful sauces, pastes, and homemade salsa. This classic Italian heirloom is a fantastic choice for gardeners who love cooking with fresh, homegrown ingredients.

For the best growth and fruit production, plant your Proven Winners® San Marzano Heirloom Tomato Bush in a location that receives at least 6 to 8 hours of direct sunlight daily. Choose well-draining, nutrient-rich soil and provide consistent moisture throughout the growing season. Allow approximately 24 to 36 inches between plants to encourage healthy airflow. Adding a sturdy tomato cage or stake will help support the branches as they fill with delicious tomatoes.

Proven Winners® San Marzano heirloom tomatoes typically begin ripening about 75 to 85 days after transplanting, depending on your growing conditions. You'll know they're ready to harvest when the fruits develop a deep, vibrant red color and feel slightly firm. Pick ripe tomatoes regularly to enjoy their exceptional flavor and encourage continued production. Whether you're preparing fresh pasta sauce or preserving your harvest for later, these versatile tomatoes bring authentic Italian flavor straight from your garden to your kitchen.
