i use 2 meter long 1" garden stakes in conjunction with a bamboo stake
(yellow) app 5 foot long. i also prune my tomatoes to around 4 or 5 stems.
it takes 2 stakes and 1 bamboo per plant. using sisal/hemp twine tied loosly
around the base of the plant we weave the twine up around each stem and tie
it to the bamboo which is the top piece tied between the 2 stakes. tghe
garden stakes are driven into the ground (just deep enough to do the job)
either side of the plant. we do this as soon as the plants start to get
leggy enough then just keep training the vine around the twine as the plant
grows.
