I have such a problem staking my tomatoes, they always seem to collapse once they get huge in they summer. I love, love these DIY sturdy tomato cages!! I'm totally going to make these for my tomatoes this year.
How to Tie Tomatoes. There are two reasons to tie tomatoes, and there's a different tie for each one. Train the leader to grow upright with a loose, figure-eight tie. To support burgeoning fruit, loop a long tie above a fruit cluster, and tie it to the stake 6 to 10 inches higher. Loop the tie twice around the stake and tie it tightly so the tomatoes dont pull it down with their weight.
