I use the Arrow T59 Staple gun and the appropriate Stainless Steel T59 Staples. On large mature trees I have found that the staples seem to grow out with the bark and the tree's do not need re-wiring (ever?). I have hundreds and hundreds of mature trees with wires in them attched this way, some done 8 years ago and I have never had to re-wire them. On small, young, immature trees things are a bit different and you will have to return to re-staple the tree on a bi-annual basis or so. Fast growing species like immature poplar might require annual re-stapling. I have seen many different methods of attaching wire to trees and the T59 SS staple is the neatest, cleanest, most effective and efficient system I have come across.
