🌾 Sow directly in the garden — Cocozelle Italian Heirloom Zucchini is not usually started indoors.
Direct sow seeds outdoors only after the last frost date has passed and soil temperatures have warmed sufficiently for germination.
Soil, care & harvest
Prepare loose, well-draining soil with a pH between 6.0 and 7.0 to ensure optimal growth. As a warm-season crop, you must wait until after the last spring frost when the soil has warmed up; do not sow indoors for transplanting as zucchini roots are sensitive and it is best direct-sown. Plant seeds about one inch deep in full sun, where they typically germinate within seven to ten days.
Space plants 36 to 48 inches apart to allow vines room to spread without overcrowding. While this variety has a compact habit reaching only one to three feet tall, it does not require trellising. Provide consistent moisture by watering one to one and a half inches per week, keeping the soil evenly moist but avoiding waterlogging to prevent root issues.
Watch for squash bugs, cucumber beetles, aphids, and vine borers; remove pests manually or use row covers early. Prevent powdery mildew, downy mildew, and bacterial wilt by ensuring good air circulation and avoiding overhead watering. Harvest zucchini when fruits are young and tender, typically fifty-five to sixty-five days after planting.
