Roll the mesh onto the ground and count 13 squares. Using small bolt or standard wire cutters, cut the wire at the end of the thirteenth square leaving intact12 squares. Allow the mesh to form a cylinder and wrap the cut pieces of the final squares around the first squares to hold the shape. Adjust the height of the cage by cutting entire squares, if desired, depending on the type of tomatoes you are growing.
Cut the wire at the base of the cylinder to create prongs that can extend into the ground when placed around the tomato plant. This will provide some security for the cage. For additional support, drive a T-post into the ground next to the cage and tie the cage to it.
These sturdy cages will last multiple years but are bulky and require extra storage space. Cages that fold flat or can be disassembled are available from Texas Tomato Cages, Titan Tomato Cages and other sources. These can be costly and will still require staking if you grow in a windy area. (Cynthia Domenghini)
