At the orchard we have really sturdy and strong tomato cages for our gardens that we make ourselves out of concrete reinforcing wire (or mesh). The cages last for many seasons and are tall enough to support even the bushiest indeterminate tomato plants. Last year Toshio made some new ones and we took photos so we could better share how to make them.

Above is a photo of one of the gardens this year, showing tomato cages we made.
