I see by your address that you are in the UK? Tomatoes here in central
Texas grow HUGE! Like over five feet tall and maybe 3-4 feet wide. A
bamboo cane would never hold that!!

I've used the cement reinforcing wire bend into a circle and it's lasted
forever. I also cut off the bottom so I have the prongs pointing down
that I can stick into the soil to help support the cage. Now, I just
can't grow tomatoes 'cause I moved into the city where there are MORE
deer and even tomatoes don't stand a chance.
