Days To Maturity

Days To Maturity

Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.

Various strains of San Marzano exist; this strain was selected by tomato breeder Emily Rose Haga from seeds from the USDA gene bank, which is designed to preserve genetic diversity and increase food security. The strain originates from Parma, Italy, where it was developed for the 1950's canning industry. This strain has a very traditional San Marzano shape and appearance as well as a vibrant red color. Indeterminate. USDA Certified Organic.

SCIENTIFIC NAME: Solanum lycopersicum
DETERMINATE (Bush): Varieties do not need pruning and may be grown with or without support; fruit ripens within a concentrated time period.
INDETERMINATE (Climbing): Varieties should be staked, trellised, or caged, and pruned for best results; fruit ripens over an extended period.
CULTURE: Medium-rich soil with pH 6.0–6.8 preferred. Fertilize accurately since excess nitrogen causes rampant growth, rot, and delayed ripening. For short determinates, succession-plant every 4–6 weeks. Tomatoes typically germinate in 5–7 days.
TRANSPLANTING: Don't start too early—leggy, root-bound, or flowering transplants can cause stunting and reduce early production. About 5–6 weeks before transplanting, sow 1/4" deep in 20-row flats with 20 seeds/row, or in 200-cell trays with 1 seed/cell; lightly cover. Keep mix at 75–85°F (24–29°C) with moderate moisture. At first true leaf, pot-up to 50-cell trays or 4" pots, depending on expected transplant timing. Grow at constant 60–70°F (16–21°C) temp and use complete fertilizer until hardened-off. Supplemental lights and lower night temps control stretching. For earliest crop, plant under row cover around last frost date. Avoid exposing unprotected plants to consecutive nightly temperatures below 45°F (7°C). In rows 4–6' apart, space determinates 12–24" and indeterminates 24–36". Plant deeply to encourage adventitious rooting. Water seedlings with a high-phosphate fertilizer solution at planting to help boost early yields.
TRELLISING: Basket-weave by pounding 5–6' stakes every 2–3 plants, using heavier t-posts intermittently and at ends of beds. For tall indeterminates, consider short extensions or pruning once they outgrow a manageable size for easy harvest.
PRUNING: Indeterminates likely benefit by removing all suckers under the first strong branch directly below the first flower cluster. The lower bottom suckers often miss trellis supports, set fruit closer to soil, take energy from upper parts, and encourage spread of disease from soil. If needed later in season, consider thinning out leaves to increase airflow or topping plants to help finish ripening last fruits.
DISEASES & INSECT PESTS: Learn your common pests and options for control, including resistant cultivars and pesticides. Avoid wet leaves and handling when wet or using tobacco products. Manage plant debris and crop rotations.
HARVEST: Fruits ripen gradually from the blossom end to shoulders and from the base of clusters to the tips. Harvest softer fruit unstacked into shallow, padded trays. Use fully ripe fruit only for local retail or home-use. To deliver sound fruit, pick less ripe the further the distance and the longer the time between field and customer. Any fruit breaking color will still ripen post-harvest. Calyx can be removed or kept to prove freshness. If staking larger fruit with calyx on, consider trimming below shoulders when harvesting.
STORAGE: Store blemish-free, near-ripe fruit 4–7 days at room temperature in darkness. Store longer with proper variety selection, picking less-ripe, and keeping at cooler temperatures 45–60°F (7–16°C). Colder and picking too green will sacrifice end-quality.
DAYS TO MATURITY: From transplants.
TRANSPLANTS: Avg. 850 plants/1,000 seeds, 10,200 plants/oz.
SEED SPECS: Avg. 11,000–13,000 seeds/oz.
PACKET: 40 seeds, unless otherwise noted; plants about 60 feet.
