|Large cushaw squash, reaching 20-30 lbs. Slight pear shape, yellow to orange flesh is great for making pies. A rare heirloom, the seed is originally from the area of Gila Cliff Dwellers in southern New Mexico. There is a great variety in shapes, colors and types of squash, making them fun to grow. Growing pumpkins can be a great project for kids. The vines need plenty of room to sprawl, although some can be supported on a trellis. Summer or winter squash or pumpkins should be sown indoors in flats in short season areas, 3-4 weeks before the night soil temperatures have warmed up. Seedlings should be gradually hardened off. Plants prefer rich, compost enriched soil. They will cross pollinate within their species. After harvest they should be ripened for 30 days in a cool location.
