Days to Maturity: Approximately 70-80 days from transplant to first harvest (often 75 days typical; continues producing well into the season).
Sun Needs: Full sun with at least 6-8 hours of direct sunlight daily—essential for good fruit size, deep color, and rich flavor 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 5–7 feet tall; strong staking, caging, or trellising is essential to support heavy fruit loads and keep plants upright—prune to 2-3 main stems for better manageability. Space 24-36 inches apart.
Other Notes: Excellent disease resistance and heat tolerance; watch for cracking from uneven watering—organic mulch (like straw or compost) helps retain steady moisture and reduce soil splash; very productive with beautiful dark fruits that stand out in the garden.
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 to support 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 dark and firm—pick regularly to encourage continued production and enjoy peak sweetness.
