I grow my annual vines on a fence I put up in spring and take down in fall. I work up the amended soil every spring. The plot is 100' x 100'. I drive 6' metal cattle fence posts in the ground 10' apart in a 100 foot row. I string poly baler twine horizontally at 1' high, 3' high & 5' high. I then drape fruit tree netting from the top line of twine and anchor it here and there to keep it in place. Here is a picture of hyacinth vine on the trellis.
