Our home-made tomato cages are extremely sturdy, as we make them from rebar.  Standing 5' tall and about 2' in diameter, they support even the largest tomato plants, and when staked will withstand Nebraska's high winds.  They're great for training your tomato to grow vertically, so you can grow more tomatoes in a smaller space.  They are $15 for one, $25 for two.  Stop by the Dundee Community Garden at 4902 Underwood to purchase your tomato cages!
