🌾 Sow directly in the garden — Zucchini Ambassador is not usually started indoors.
Direct sow seeds outdoors only after all danger of frost has passed and soil temperatures have warmed sufficiently for germination.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.0 before planting outdoors. As a warm-season crop, you must wait until after the last spring frost when the soil has warmed up; do not sow early. Sow seeds directly into the ground at a depth of about one inch. Expect germination to occur within seven to ten days under these warm conditions.
Space plants thirty-six to forty-eight inches apart to ensure proper air circulation and growth. While this variety grows compactly, it does not require trellising. Provide consistent moisture by watering one to one-and-a-half inches per week. Apply mulch around the base to retain soil moisture and feed the plant regularly during the active growing season.
Watch for squash bugs, cucumber beetles, and vine borers; use row covers or hand-pick pests early. Prevent bacterial wilt and downy mildew by ensuring good airflow and avoiding overhead watering. Harvest fruits forty-eight to fifty-five days after planting when they are firm and glossy. Cut them from the vine with a sharp knife to avoid damaging the plant.
