They are just beautiful. I have some cages and some twisty stakes. I don’t know which is better. The twists are neat until the tomato outgrows them and then you have a tangle.
The cages don’t need any attention, but they are expensive — $10 each for the nice ones. I don’t like those old conical wires. They fall over when the plant gets big and are a mess to store.
Again, you have the perfect solution.
Have you started a book yet? You need to.
Really, it is the velcro garden tape that is the perfect solution ... the rebar is just plain ol' cheap. :^)
