How to Plant and Grow Winter Squash
Direct sow when soil is at least 70°F., and weather has settled. Seeds will not germinate in cold soils. Start Winter Squash seeds indoors 3-4 weeks before the last frost or direct seed once all danger of frost is past. Vining plants need at least 4 to 5 feet of garden space for best fruit production. Winter squash should remain on the vines until fully hardened but removed before the first fall frost.
