How to Build Tomato Cages from Wire


Tomato cages must support the rapid growth of the fruiting vegetable plant. Many cages, made from small-gauge wire, frustrate the tomato grower because the lightweight cage tends to fall over. The best material for making your own tomato cage is a heavy-duty concrete reinforcing wire mesh. The heavy gauge wire, along with the large 4-inch-square openings, allow for easy access to the ripening fruit. In most all cases, concrete reinforcing mesh wire will last up to 15 years or more, and the round cages can be stored outdoors.

Step 1

Put on leather gloves safety glasses. The concrete reinforcing wire has sharp edges, and small particles may fly when it is cut.

Step 2

Roll out approximately 5 feet of the concrete wire.

Step 3

Cut the concrete wire at 5 feet, using the heavy-duty cutting pliers, down the center of the horizontal wires on the fencing.

Step 4

Bend the cut horizontal wires into a small, open-loop hooks.

Step 5

Fashion the concrete wire into a round cage. Use the open loop hooks to tie the two ends of the cage together. You may wish to twist the open loop hook around the vertical portion of the fencing, and twist the loop closed with pliers.

Step 6

Set the new wire tomato cage over the tomato plant. Weave one of the wooden stakes through the lower open weaves of the fencing. Use a hammer to drive the wooden stake approximately 6 inches into the soil.

Step 7

Weave the other stake through the cage directly across from the first one and drive it into the ground. The two stakes will hold the cage in place for extra support.
