Days to Maturity: Approximately 65-75 days from transplant to first harvest (often 70 days typical; continues producing heavily over a long season).
Sun Needs: Full sun with at least 6-8 hours (ideally more) of direct sunlight daily—critical for abundant clusters, deep color, and rich sweetness in Utah’s intense summer light.
Season Type: Warm-season crop; frost-sensitive—transplant only after soil warms to 65°F+ and all frost danger has passed (late May to early June in the Salt Lake City area).
Plant Habit & Support: Indeterminate vining plants grow 6-10 feet or more; strong staking, caging, or trellising is essential to support heavy fruit clusters, keep plants upright, and improve airflow—prune to 2-3 main stems for better manageability. Space 24-36 inches apart.
Other Notes: Excellent productivity and flavor; watch for aphids, hornworms, or cracking from uneven moisture—organic mulch (like straw or compost) helps retain steady moisture and reduce soil splash; very prolific with fruits that hold well on the vine.
Best Planting Method: Transplant when nights stay above 55°F and soil is warm. Space plants 24-36 inches apart in rows or beds; bury stems deeply (up to the first set of true leaves) to encourage strong roots. Amend soil with compost for fertility and excellent drainage—raised beds are ideal in heavier or alkaline Utah soils to improve root health and prevent issues. Organic mulch (such as straw, compost, or grass clippings) around plants conserves moisture, suppresses weeds, and moderates soil temperature.
Watering Needs: Provide consistent, deep watering (1-2 inches per week) to keep soil evenly moist, especially during flowering and fruit development—drip irrigation is ideal in dry Utah air to keep foliage dry and minimize disease. Avoid fluctuations that cause cracking or blossom-end rot; mulch helps maintain steady moisture, and containers may need more frequent checks during hot spells.
Fertilization Needs: Incorporate compost or balanced slow-release fertilizer (e.g., 10-10-10) at planting. Side-dress with a higher-phosphorus/potassium formula (like 5-10-10) when flowering begins and again midway through the season to support extended fruit production over excess foliage. Tomatoes are heavy feeders—avoid high nitrogen late in the season to prevent leafy growth at the expense of fruit; organic options like compost tea provide steady nutrients. Harvest when fruits are fully chocolate-brown and slightly soft—pick regularly (every 2-3 days) to encourage continued heavy production and enjoy peak sweetness.
