My husband made me a large side by side compost bin / potato box a couple of years ago that was actually featured in Mother Earth News. Well, this year I was busy and didn't get around to shifting it out. There was a bumper crop of Roma and Cherry tomatoes that popped up on their own as well as some cucumber plants. I decided to let them be. Then ... a big old squash plant started growing. I had no idea what it would be. Maybe a pumpkin? Today I was pulling out the spent plants and came across this monster! Still don't know what it is. Maybe spaghetti squash?
