I got a couple of 4x4s and some of the heavy duty wire I already had for grape vines I figure I could at least add to it as they grow .I got 12 foot ones and will cement them into the ground 2 feet and then run the wire like a cable system and that way if I have too I can just buy more 4x4's and add to it .These say they just need support for the limbs until the get strong enough
