This year I decided that I wanted to grow a few pumpkins. I like Pie. So I went and started some seedlings, planted them, and a few weeks later they were thriving and happy pumpkin vines. However I ran into a slight problem. Connecticut Field Pumpkins grow like mad. They were threatening to take over my garden and the back yard.
I needed space for my tomatoes, aliums, and other cucurbits, so I scoured the internet. Somewhere, I found a picture a guy had of a forest somewhere--with pumpkins growing in a tree. The vine had apparently climbed the tree, and set fruit high up in a tree. There's also this news article about the Greenfield, Iowa couple who found a pumpkin growing in their pear tree
So I thought to myself, if they can grow in trees, why not up and onto the roof of our garden shed?
