📷 Wikimedia CommonsStarting Zucchini Dark Green: indoors or direct sow?
🌾 Sow directly in the garden — Zucchini Dark Green is not usually started indoors.
Direct sow seeds outdoors only after the last spring frost once soil temperatures have warmed sufficiently.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.0 for optimal growth. As a warm-season crop, wait until all danger of frost has passed and the soil is fully warm before sowing directly outdoors; do not start indoors as this species does not transplant well. Press seeds about one inch deep into the earth. Expect germination to occur within seven to ten days under these warm conditions.
Space plants thirty-six to forty-eight inches apart in full sun, ensuring they have room for sprawling vines. Water deeply once or twice weekly to provide one to one-and-a-half inches of moisture, avoiding wetting the foliage. Apply a thick layer of mulch around the base to retain soil warmth and suppress weeds, while feeding lightly if fruit production seems sluggish.
Watch for squash bugs, cucumber beetles, vine borers, and aphids; remove them by hand or use row covers early. Prevent powdery mildew, bacterial wilt, downy mildew, and blossom end rot by ensuring good air circulation and consistent watering. Harvest fruits fifty to fifty-five days after sowing when they are firm but still tender for the best flavor.
