I erected a long pole made up of 3 bamboo stalks lashed together, with a ring strung up by a pulley. The twine is tied to this ring so I can lower it at the end of the season to harvest the whole vine. The bottom end of each twine is tied to a 2' bamboo stake, driven 1' into the ground behind the base of each plant. This is the first year I have tried this. The top of the pole is approximately 23' off the ground. The other pole in the foreground was from trying to grow tomatoes out of the bottoms of 5 gallon buckets last year.
