Tomatoes need support, but tomato cages can get expensive.
If your planning to use raised beds anyway, why not build a tomato arbor? you can use wood from the store or materials found around your property. I decided to go with poles and wire and a bunch of free straw.
First I set the posts and wrapped the posts with old chicken wire and filled the wire with straw. Next I put the beams across the posts s that when my tomatoes get bigger, i can support them with twine.
Thats literally it, a raised bed and supports for tomatoes, completely free. everything including the straw!
