The galvanized nails are a better choice, just make sure they are sharp to start with, no spikes. The location is the big problem in tree selection. I want fruit and citrus but until I finally select my growing area, I can't select the best tree's. Big temp difference for 1 to 2,000 feet above seal lever and 5 or 6,000 feet above sea level. The low desert allows longer grow seasons and defense visibility (mountain / hill top compound) but the upper / high desert offers fire wood and more hunting animals / food. The price of the land is fairly close in price, so again it just comes down to my making a choice. Waffle, waffle.
