🌾 Sow directly in the garden — Zucchini Partenon is not usually started indoors.
This plant is a warm-season crop that should be sown directly into the garden only after the last frost date and once soil temperatures have warmed sufficiently.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.0 before sowing. As a warm-season crop, you must wait until after the last frost when the ground is fully warm; do not start indoors. Sow seeds directly at a depth of about one inch. Germination typically occurs within five to eight days under these ideal conditions.
Space plants 24 to 36 inches apart in full sun, ensuring consistent moisture of one to one-and-a-half inches per week. While this variety does not require trellising, apply mulch around the base to retain soil moisture and suppress weeds. Feed regularly during the fruiting stage to support heavy yields.
Watch for aphids, cucumber beetles, squash bugs, powdery mildew, and bacterial wilt. Prevent issues by inspecting leaves frequently and ensuring good air circulation. Harvest fruits when they are firm but tender, usually forty-eight to fifty-two days after planting seeds.
