I do have some 8' poles I could bang in. Well, 6' or so by the time I bang 'em in through loose soil to get down to where they'll hold upright. I can put double tomato cages over them and stake the cages so they don't fall over in wind.
Stakes or cages? From y'all's comments I have a feeling that either way, these guys are gonna get "interesting".
That's the fun of trying something new!
