Begin seeds approximately 7–9 weeks before the expected last spring frost. Sow about 1\/4 inch deep in a moist, well-drained seed-starting mix.\u003c\/p\u003e\n\n\u003cp\u003eUnder favorable conditions, germination commonly takes about 7–10 days at approximately 65–85°F. Once seedlings emerge, provide strong light to encourage compact, sturdy growth.\u003c\/p\u003e\n\n\u003cp\u003eHarden seedlings gradually before transplanting. Move them permanently outdoors only after frost danger has passed and warm weather has arrived.\u003c\/p\u003e\n\n\u003ch3\u003eSpacing \u0026amp; Support\u003c\/h3\u003e\n\n\u003cp\u003eSpace plants approximately 18–36 inches apart. Vigorous indeterminate tomatoes benefit from extra space and airflow.\u003c\/p\u003e\n\n\u003cp\u003eInstall a strong cage, stake, string system, or trellis at planting time. Unlike determinate tomatoes, indeterminate San Marzano vines continue extending and producing flower clusters throughout the season until frost stops growth.\u003c\/p\u003e\n\n\u003ch3\u003eWatering \u0026amp; Feeding\u003c\/h3\u003e\n\n\u003cp\u003eMaintain regular, even moisture throughout growth and fruit development. Avoid repeated cycles of severe drying followed by heavy watering.\u003c\/p\u003e\n\n\u003cp\u003eUse fertile, well-drained soil. Excessive nitrogen can create lush foliage while delaying flowers and fruit, so follow soil-test recommendations when possible rather than over-fertilizing.\u003c\/p\u003e\n\n\u003ch3\u003eHarvest \u0026amp; Enjoy\u003c\/h3\u003e\n\n\u003cp\u003eSan Marzano generally reaches maturity about 85 days after transplanting under suitable conditions. Harvest when the fruit develops a full red color.\u003c\/p\u003e\n\n\u003cp\u003eBecause this is an indeterminate tomato, harvest is spread across the season rather than concentrated into a short period. Pick ripe tomatoes regularly so the plant can continue supporting developing fruit.\u003c\/p\u003e\n\n\u003cp\u003eThe meaty, relatively low-juice fruit makes San Marzano particularly useful for tomato sauce, paste, canning, soups, stews, roasting, and other recipes where concentrated tomato flavor is desired.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to Expect\u003c\/h3\u003e\n\n\u003cp\u003eTrue Leaf's current San Marzano Indeterminate listing contains two different fruit-size descriptions, so we do not promise a fixed fruit length or weight. Actual fruit size varies with strain, weather, fertility, pruning, irrigation, fruit load, and growing conditions.\u003c\/p\u003e\n\n\u003cp\u003eLikewise, mature vine height varies considerably. Indeterminate plants may reach approximately 3–8 feet depending on support, pruning, season length, and growing environment.\u003c\/p\u003e\n\n\u003ch3\u003eAbout the San Marzano Name\u003c\/h3\u003e\n\n\u003cp\u003eSan Marzano is a recognized tomato variety\/type that can be grown in home gardens outside Italy. However, the protected designation “Pomodoro San Marzano dell'Agro Sarnese-Nocerino” PDO\/DOP applies only to qualifying tomatoes produced and processed according to the official geographic and production specification in Italy.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch3\u003eIs this San Marzano determinate or indeterminate?\u003c\/h3\u003e\n\u003cp\u003eThis listing is specifically for San Marzano Indeterminate. The vines continue growing and producing tomatoes through the season until frost.\u003c\/p\u003e\n\n\u003ch3\u003eHow long does San Marzano take to mature?\u003c\/h3\u003e\n\u003cp\u003eExpect approximately 85 days from transplant under suitable growing conditions. This maturity figure is counted from transplanting, not from the day the seed is sown.\u003c\/p\u003e\n\n\u003ch3\u003eDoes San Marzano need a trellis or cage?\u003c\/h3\u003e\n\u003cp\u003eYes. Indeterminate plants can become tall and heavy with fruit, so sturdy staking, caging, or trellising is strongly recommended.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is San Marzano best used for?\u003c\/h3\u003e\n\u003cp\u003eIts meaty paste-type fruit is especially suited to sauces, tomato paste, canning, roasting, soups, and stews, although ripe fruit can also be eaten fresh.\u003c\/p\u003e\n\n\u003ch3\u003eCan San Marzano grow in a container?\u003c\/h3\u003e\n\u003cp\u003eIt can be grown in a sufficiently large container, but this indeterminate form becomes much larger than compact determinate tomatoes. Use a large container, strong support, full sun, and consistent moisture.\u003c\/p\u003e","brand":"Mai's Family","offers":[{"title":"100 Seeds","offer_id":67898152943922,"sku":"693039732174","price":2.99,"currency_code":"USD","in_stock":false},{"title":"200 Seeds","offer_id":67898152976690,"sku":"693039732175","price":3.99,"currency_code":"USD","in_stock":false},{"title":"500 Seeds","offer_id":67898153009458,"sku":"693039732176","price":4.99,"currency_code":"USD","in_stock":false},{"title":"1000 Seeds","offer_id":67898153042226,"sku":"693039732177","price":5.99,"currency_code":"USD","in_stock":false},{"title":"5 Grams","offer_id":67898153074994,"sku":"693039732178","price":12.99,"currency_code":"USD","in_stock":false},{"title":"10 Grams","offer_id":67898153107762,"sku":"693039732179","price":19.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/9743\/2114\/files\/maisfamilty.png?v=1790909505","url":"https:\/\/maisfamily.us\/es\/products\/san-marzano-indeterminate-tomato-seeds","provider":"Mai's Family","version":"1.0","type":"link"}
