So, the guy who purchased the 7 acre tract behind my house cleared the nice hedgerow separating our properties, so that I'm looking into his lot from my house, and vice versa. Since my house sits up on a bluff, and our property line is (unfortunately) the low spot between the properties, any hedgerow I re-plant will need to gain some height, to be a real effective block, sighting house-to-house. My wife suggests waiting until their house is in, and we know exactly what we're dealing with before planting, but I'd rather get a jump on it. I suspect fall may be the best time to plant such a hedgerow, and besides... I suspect it will be less likely to upset the new guy, who wants to see his house from the street (thru my yard), if the hedgerow is put in before he builds, rather than in reaction to it. So, is fall the best time to plant? If you had to block roughly 200 feet of property line, perhaps 30 feet high, what would your planting schedule look like? Since the soil is a little wetter in this lower area, that pushes me toward Norway Spruce and Green Giants. Since a large portion of my property is Black Walnut trees, and Norway Spruce does not like Black Walnut (Juglone), I'm sort of forced toward the Green Giants for some large back-row growth. I'll try to get measurements and a drawing of the existing trees done in the next day or three, as I'll be planning (planting) around those. These are a mix of Black Walnut, Silver Maple, and Ash. I am also considering the addition of another tree (oak, sweet gum, Linden), in one large gap between two of the large silver maples.
