Gardener's Blue Ribbon TMC60 Ultomato Tomato Plant Cage
This is the only build-it-yourself tomato cage on this list, and that type of design and versatility make this the #3 pick. The Gardeners Blue Ribbon Ultomato Tomato Plant Cage comes in a basic package with three poly-plastic stakes and clip-on supports. You can attach the supports anywhere along the height of the stakes for a custom made fit that will support virtually any tomato plant. Although the stakes are made of a poly-plastic material and will not rust or rot, as long as they are not abused, they will last as long as a metal stake. If you have many different types of tomato plants that will grow to different widths or heights, you can custom make this cage to support virtually any plant that you have.
