When I approach a project 30’x100’, I want to eliminate as much down the road work and heartache as possible. Deer, rabbits, and weeds will all combine to make that a money pit and a time eater. May I suggest a 20 rod roll of Redtop field fence, 48" chicken wire hog ringed to the bottom 36" of the field fence rolled outwards at the bottom, and weed barrier like Fruitnut has pictured in his greenhouse? For me this has kept chickens in, predators at bay, deer and rabbits out and my precious apples safe. Initially very labor and money intensive, but now I pitch a little roundup in and don’t fret too much about vermin in my apples. For irrigation that size, I want drip tape and layflat hose. Quality doesn’t cost, it pays. Do it right the first time and then you won’t have to do it right again.
