Every year I have one big experiment. This year it is a new, in the garden, compost bin. The inspiration came from a P. Allen Smith show on PBS way back in the dark days of winter. Very simply it is a wire cage linked into a tube around which are planted three tomatoes. The wire cage serves as a compost bin that, as garden and food waste is breaking down, fertilizes the tomatoes. It also keeps the tomatoes consistently moist and has, through this chilly Spring, kept the plants warmer. Here, now the end of May, the plants are taller than me, and are loaded with tomatoes. When the plants die back I'll let the compost finish breaking down and dig it into the garden. So simple! So brilliant!
