Growing Organic San Marzano Determinate Paste Tomatoes in the Vegetable Garden
San Marzano Determinate seeds are best started 6-8 weeks before the final frost. Begin sowing tomato plants in early spring with a seed-starting container under grow lights or in a greenhouse. Plant seeds 0.25 inch deep in a warm, moist seed-starting mix. Germination will take 1-2 weeks. You can transplant Organic San Marzano Determinate Tomato seeds outdoors once the threat of frost has passed or once your area’s lowest temperatures exceed 55 F. These plants prefer full sun and a temperature range of 65-95 F with a minimum of 50 F for germination. After 6 weeks, or once seedlings grow about 4-6 inches tall and have 2 sets of true leaves, harden them off before transplanting them outdoors. Once you are ready to transplant, till rich, composted soil in your planting location of choice. Then, remove the lower leaves on each San Marzano plant that will end up below the soil. Plant them deeply, as tomatoes are able to develop roots along the buried stem. This method increases root development and improves plant establishment rates. Space the plants 2 feet apart with 3 feet in between rows.
Use a trellis or stake for support as the plant grows. You can also transfer Organic San Marzano Determinate Red Tomatoes to a container at least 14-20 inches wide and 12 inches deep to set on your patio, as this small and shorter bush type grows 3-4 feet tall and doesn't take up too much space. Feed your San Marzano tomatoes by scattering your fertilizer of choice (compost tea also works) at the base of the plants throughout the season. Be sure to follow any directions on the fertilizer packaging. Water San Marzano plants regularly, but avoid standing water. In general, tomatoes prefer full sun and rich, warm, well-draining soil with added compost and a pH level of 6.0-6.8.
Harvesting Organic San Marzano Determinate Paste Tomatoes
Harvest San Marzano Determinate Tomatoes once their red color is bright and before they feel too soft. In general, it's recommended to begin harvesting canning tomatoes once they start to turn red. Harvest tomato plants by gently pulling the bright-red fruit from their green calyx hat with one hand while holding the stem with the other. Ripest tomatoes may be pulled from the vine by hand, while more firm ones should be clipped with shears. San Marzano Determinate paste tomatoes are a determinate bush variety and will have just a few weeks of intense harvest.
About Organic San Marzano Determinate Paste Tomato Garden Seeds
Organic San Marzano Determinate tomatoes are suitable for growing in garden plots, containers, raised beds, and greenhouses. Often compared to the well-known Roma tomato in reference to shape, size, and flavor, San Marzano seeds grow an Italian cultivar commercially produced throughout the 20th and 21st centuries. Introduced in 1926, San Marzano seed has become an Italian staple where it is known locally in Valle del Sarno as "Pomodoro San Marzano dell'Agro Sarnese-Nocerino.''
Determinate tomato plants are the type that pickers like because they are easy to reach and become ripe for harvest around the same time. Nice, short, determinate vines produce heavy yields of bright red, 2-3 Inch, 5-6 ounce, plum-type fruits. San Marzano is the premier canning tomato in Italy, with heavy walls, very few seeds, and little juice.
Tomato fruits are rich in lycopene. It is thought that this antioxidant reduces the risk of heart disease and is good for the eyes, potentially protecting against macular degeneration. It also may help prevent prostate cancer as well as intestinal cancers. San Marzano Determinate tomatoes also provide vitamin C, vitamin K, and potassium.
