Exclusive! Early San Marzano type.

Developed in Italy, Tiren produces meaty, 5–6 oz. fruits with the classic San Marzano shape. Tiren’s interior has very little gel, making it our fastest variety to boil down into sauce. Tiren can be harvested with green shoulders to ripen fully in storage, or can be left on the vine a little longer until it is red-ripe. Indeterminate.

Disease Resistance:

Fusarium Wilt races 1 (High)

  • Tomato Mosaic Virus (High)
  • Verticillium Wilt (High)

    Specs:

    • Packet: 40 seeds
    • Avg. 11,500 seeds/oz

  • Size

    Packet, 250 Seeds, 1,000 Seeds, 5,000 Seeds

    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
