When I first started growing tomatoes, I bought those little conical tomato cages. Right from the start I began having problems with them. My tomatoes grew and grew and spilled over the tops of their cages, toppling them over. So back to the hardware store I went to get taller and sturdier tomato cages. But, since I grew indeterminate heirloom tomatoes which tend to grow long vines throughout the entire growing season, even the sturdiest, most heavy duty tomato cages still toppled over from the combined weight of plant and fruit.
I began reinforcing the cages. I planted tomatoes in a grid overlapping the cages slightly at the top. I pounded tall electrical conduit rods into the ground, weaving the rods through the overlapping cages which stabilized them and prevented them from falling. I further reinforced the mesh of cages by tying them together with the long thin bags that the daily newspaper came in.
And then I discovered a new way to trellis my tomatoes – the Florida Weave. I like that name. It sounds like the name of a dance – a dance for a gardener and her tomatoes using no cages, just stakes and twine.
I plant tomatoes 
about 18” apart in a row. Every two tomatoes, I pound in a wooden stake using a brilliant tool – a post pounder. At the ends of the rows, I pound in metal stakes at an outward facing angle.
When the tomatoes are about a foot tall, the dance begins. As with any dance, one needs the right attire. For this dance, instead of dance shoes, I use box of tomato twine. Twine comes out of the top of the box and the box has belt loops for attaching to a belt.
I tie the twine to a stake at the end of a row. Then I walk down one side of the row, spooling twine out from the box at my hip, weaving the twine around a post, against the tomatoes, around the next post, forming a figure-eight with the twine and sandwiching the stems and branches of the each tomato plant between lengths of twine. 
I tie off the twine back at the starting point and then wait for the tomatoes to grow some more. When they have grown another foot, I go back out to dance with the tomatoes again.
And so, as the tomatoes grow, I trellis them every foot or so with a weave of twine.
An added bonus of using the Florida Weave is that I no longer have to struggle with stacking bent tomato cages at the end of the season and finding a place for the accumulating stacks. I grow a lot of tomatoes and those stacks of cages were so very awkward. In fact, last year, I gave away all my tomato cages. At the end of the season, I simply cut away the twine, pull up the stakes, and store them in a corner of my garden shed.
While the Florida Weave is usually recommended only for determinate tomatoes, I have successfully used this method with my indeterminate heirlooms. I’ve also used the Florida Weave with other vining plants, such as peas. I love the simplicity and beauty of this trellising method and the routine of tending to my plants as they grow.
