Days to Maturity: Approximately 60-70 days from transplant to first harvest (often 65 days typical).
Sun Needs: Full sun with at least 8 hours of direct sunlight daily—essential for good fruit set, size, and flavor in Utah’s intense summer conditions.
Season Type: Warm-season crop; frost-sensitive—transplant only after soil warms to 70°F+ and all frost danger has passed (late May to early June in the Salt Lake City area).
Plant Habit & Support: Upright, bushy plants grow 24-36 inches tall and wide; light staking is recommended to support heavy fruit loads—space 24-36 inches apart.
Other Notes: Very productive with long, uniform fruits; watch for flea beetles, aphids, or verticillium wilt—organic mulch (like straw or compost) helps retain moisture and reduce soil splash; harvest when fruits are glossy, firm, and reach desired length (before they lose shine or seeds harden).
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 letting plants wilt or overwatering; 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. Eggplants 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 with pruners when fruits are glossy and firm—regular picking encourages more production.
