Hi John.
When I started farming I was determined not to use any chemicals of any sort and I was pretty obsessed with keeping heirlooms pure.
After a year of trying to grow squash and various heirloom pumpkins I had failed miserably. Squash bugs and borers had killed all of my plants.
I was very disappointed and was ready to give up on permaculture. During the next growing season I posted some of my frustrations here. Joseph Lofthouse and others helped me see things from a different perspective. He suggested planting several varieties and saving seeds from whatever I harvested. That year I was able to save a few seeds from one pumpkin that had nearly reached maturity. The next year those few seeds yielded a wheelbarrow full of a new, unique variety. They were beautiful and delicious. The season after and every year going forward this new variety was unstoppable. Even though they were covered in squash bugs there was never any harm to the plants or fruit.
Until poor health dictated that I sell the farm a decade later I continued to farm this way. Before I left I gave all of those seeds to a few young farmers who are growing them this year. I’m thrilled that my struggles can help them get ahead!
