If you want a cheap and easy way to trellis your tomatoes, forget cages. The Florida Weave method goes up fast and uses everyday supplies you might already have around the yard.
Start with sturdy stakes at least 6 to 7 feet tall.
Place a stake between each plant and drive it 12 inches in the ground. If you put a stake between every two to three plants, drive it 18 inches in the ground
Use a durable, weather-resistant twine that doesn’t stretch too much, like tomato twine (a 3-ply jute works well) or synthetic baler twine.
Starting about 8 inches above the ground, loop a length of twine around the first stake and weave the twine in and out between each plant.
When you reach the last stake, loop the twine around the stake in a figure-8, making sure the twine grips the stake and the line is taut, but not pulling too tightly to damage your tomato stems.
