Yield

I'd read that you can grow potatoes in a "tire tree" made by continuously stacking more tires and dirt over the leaves and stems the potatoes put out.

My friend Jorge pointed out that tires contain cadmium, among other things, and so I tried the layering method in a plastic bucket.

It did make potatoes, but not the multiple generations I'd imagined the tire tree would produce. Next year I'll try it with chicken wire and straw or wooden produce boxes. It seems you need to get more height to get a larger yield.

I enjoy the way root vegetables yield. I imagine all the returning UT students are giving way with a similar muted *POP*.
