Dunja delivers speed and disease resilience in a compact package. At just 47 days to maturity, it's among the quickest zucchini hybrids available, while its strong resistance to powdery mildew, PRSV, watermelon mosaic virus, and zucchini yellow mosaic virus means fewer sprays and more reliable harvests. The early designation signals vigorous, trouble-free production, even in challenging growing seasons.
Dunja zucchini is grown for fresh harvest and culinary use. Pick fruit young and tender for grilling, sautéing, or slicing into salads; the compact growth habit makes it well-suited to succession plantings every 2-3 weeks, ensuring continuous supply throughout the season rather than the typical glut-and-drought pattern of traditional zucchini varieties.

Start seeds indoors 3-4 weeks before your last frost date in a warm environment (70-85°F). Sow seeds 1/2 inch deep in individual containers to minimize root disturbance at transplanting. Keep soil warm and consistently moist until germination, which typically occurs within 7-10 days.
Transplant seedlings outdoors after your last frost date when soil has warmed to at least 60°F and nighttime temperatures stay above 50°F. Harden off plants over 7-10 days by gradually exposing them to outdoor conditions. Space plants 18 inches apart in rows. Fabric row covers (AG-19 grade) can be used during the seedling stage to exclude insect pests and warm the soil; remove covers once flowering begins to allow pollinator access.
Direct sow seeds outdoors 1/2 inch deep after all frost danger has passed and soil temperature reaches 60°F or warmer. Sow 2-3 seeds per hill, spaced 18 inches apart. Thin to the strongest seedling once plants develop true leaves.
Pick fruit when it reaches 6-8 inches long and the skin is tender enough to puncture easily with a fingernail; smaller zucchini are more tender and flavorful than oversized specimens. Harvest regularly every 2-3 days during peak production to encourage continuous flowering and fruiting. Use a sharp knife or pruner to cut fruit from the vine rather than pulling, which can damage the plant.
