Tools for the trade!
Heirloom tomato plants grow up big and tall.
Heavy duty cages are needed and staking will help the plants from falling over.
I use jute string to tie up stalks that want to escape captivity.
The plants are getting heavy with tomatoes!
down to earth digs 
Lovely!
And they always try to escape the cages! 🙂
I had to the same thing over the weekend. My tomato plants are taller than I am.
Ours are strong and tall this year, too…still green, though 😀
I just tied up my tomato plant, yes I only have one after the deer got to mine, and used a fallen stick as the support. Worked for me but your tools are much prettier.
