Plant vining winter squash in rows or hills. For row planting, plant seeds to a depth of 3/4 inch, spaced 2 1/2 to 3 feet apart. Space rows 2 feet apart. For hills, mound an area of soil that is 3 to 5 feet in diameter. Plant six or seven seeds per hill. Allow 7 to 10 feet between hills as squash vine out and cover a large area.
