Kefren delivers ripe zucchini in just 50 days, a speed that makes succession planting every 2 to 3 weeks genuinely practical for a continuous summer supply. Its compact growth habit works equally well in small gardens and standard beds, and the four-disease resistance package protects against the viral and fungal threats that derail many zucchini crops. Easy harvesting and straightforward disease management mean you spend less time troubleshooting and more time cooking.
As an edible summer squash, Kefren zucchini is harvested young and prepared in the full range of traditional zucchini applications: sliced and sautéed, grilled, baked into breads and desserts, spiralized into noodles, or added to soups and stews. The quick maturity and compact plant make it particularly suited to gardeners practicing succession planting for continuous harvest through the season.

Start Kefren seeds indoors 3 to 4 weeks before your last spring frost date. Maintain soil temperatures between 70 and 85 degrees Fahrenheit for reliable germination. Transplant seedlings outdoors after the danger of frost has completely passed and soil has warmed.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days. Transplant outdoors once soil temperature is consistently above 60 degrees Fahrenheit and all frost danger has passed. Space plants 18 inches apart in rows or clusters.
Direct sow seeds outdoors after soil temperature reaches 70 degrees Fahrenheit and all frost danger has passed. Sow seeds at the spacing depth listed below, allowing soil to warm fully before planting.
Harvest Kefren zucchini when fruits reach 6 to 8 inches in length for tender, flavorful squash. Regular harvesting encourages continued flowering and fruit production throughout the season. Use a sharp knife or pruner to cut the stem just above the fruit, being careful not to damage the plant. Harvest frequently, every 2 to 3 days during peak season, to maintain quality and prevent overgrown, seedy fruit.
