Jung Seed San Marzano Tomato

Indeterminate means the plant will continue to grow, flower, and produce fruit throughout the entire growing season until the first frost. You will need to provide support, like a stake or cage, as the vines can grow quite long.

While they are famous for their thick, meaty flesh and low seed count—which makes them the gold standard for sauces and canning—they are perfectly edible fresh. However, their texture is drier than a typical slicing tomato, so they are best suited for culinary applications.

You can expect these to reach maturity in about 80 days after planting. Keep in mind that this timeline can vary slightly depending on your local climate and how much sunlight the plants receive.

Because this is an indeterminate variety that grows vigorously, it is best suited for in-ground planting or a very large raised bed. If you must use a container, ensure it is at least 5 to 10 gallons and provide a sturdy trellis system.

These tomatoes thrive in USDA hardiness zones 3-9 and require full sun, meaning at least 6 to 8 hours of direct light daily. They prefer well-draining, nutrient-rich soil, so amending your garden bed with compost before planting is always a good idea.
