|An early pale green, striped cushaw from Old Mesilla, near Las Cruces, New Mexico. Skin is very warty along the neck. Fruits reach 15 lbs. 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. 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.
