Squash originated in Central America and Mexico.  Wild squash was bitter and was originally used as cups and bottles around 13,000 BC.  People started farming squash around 10,000 and created tastier sweeter varieties.  Hundreds of different varieties are grown for food  and for their seeds around the world.  Winter squash gets sweeter the longer you store it!!

To save seeds that are true to type-these plants must be  800 feet- 1/2 mile away from all other varieties  of the Cucurbita species that you are growing . You can harvest viable seeds from one plant.  You need  5-10 plants for variety maintenance and you only need 25 plants or more for genetic preservation.
