mine dies back every year and comes back.
this is the first year it didnt die to the ground, i have a 1ft vine left,
almost an inch thick.
i use 1x2 inch 8ft stakes, and fairly thick electrical wire running between them.
ive used lattice strips nailed to the stakes before
but, they always break in a year or 2.
i havent found them that invasive. they do run a bit,
but are pretty easy to pull up. often the roots come right up when you pull at the base.
the roots are very close to the surface.
ive been thinking of digging down a bit, and boxing them in.
Last year, i must have had 80ft of vines and no fruit on my main plant.
the other one i had ,was in a 3 gallon pot, and a 6ft vine climbing a simple pole
gave me 1 nice tasting fruit .
2nd time thats happened.
they fruit more if you contain the roots.
