Golden Zucchini Summer Squash Seeds

Direct sow Summer Squash Golden Zucchini seeds 1 inch deep directly outdoors after the last frost, once soil has warmed to at least 60°F. Cold soil is the common reason zucchini seeds rot rather than germinate. If you want an earlier harvest, start seeds indoors 3–4 weeks before the last frost date and transplant once nighttime temperatures hold above 50°F. Summer Squash Golden Zucchini seeds germinate in 4–14 days depending on soil warmth. Space plants or mounds 36–48 inches apart, as squash spreads more aggressively than most people can imagine, and overcrowding leads directly to mildew problems later in the season.

Golden Zucchini needs full sun, at least 6–8 hours daily, without compromise. Plant in organic, fertile, well-drained soil with a pH of 6.5–7.0 and work compost in before planting. Water consistently, as squash roots sit shallow and dry out faster than deeper-rooted crops during hot weather. Mulch around the base of each plant to retain moisture, keep roots cooler on hot days, and reduce watering. Water at the base, and never overhead, since wet foliage is the fastest way to invite powdery mildew.

Fertilize once the plant starts flowering and again during active fruiting. Pick fruits at 6–8 inches. If Golden Zucchini left past that point it becomes seedy, the skin toughens, and the plant slows down new fruit production. Harvest every 2–3 days during peak season. Monitor for squash bugs, vine borers, and cucumber beetles; these three pests cause the most damage to this crop.
