I was asked to post this with a photo. It is my way of staking tomatoes. I don't like using on stake going down through the roots so I use four stakes made from rough cut oak lumber that I can very inexpensively and binders twine. I do not rap the twine around the four stakes, I find when I support the branches that way the weight of the tomatoes will either badly bend or break the branch. Now I run the twine between two stake on a diagonal keeping the branches growing upwards and the flowering buds inside the four stakes. So far it has worked well. I hope you can see the twine, a pointed oval.
