Winter squash is an annual fruit representing several squash species within the genus Cucurbita. It differs from summer squash in that it is harvested and eaten in the mature fruit stage. Our packs have around 20 plus seeds for the fancy ones and around 50 for the normal ones; there are around 2500 to 4000 seeds per pound. It takes around 6 pounds of seed per acre; and you can have a semi load of winter squash! When I grew for pie sales, I'd figure about one semi load per acre. That's a lot of squash!
