I planted two apple seedlings, a Liberty and a Russet, in my front yard late last spring. They've both taken very nicely, almost doubling in size. Heading now into an eastern Ontario winter, I'd like to protect them against two potential hazards, salty sidewalk snow piles and mice. Salt: The trees are about 6 feet back from the sidewalk and a narrow, older street. Plowing is usually done first on the street, pushing onto the sidewalk, and eventually the sidewalk gets plowed, pushing that onto our yards. When I planted the seedlings, I put three stakes of narrow gauge rebar around each, and a bit of wire connecting them at 1' intervals upward, more to inhibit street vandalism (eg. snapping) than to support the trees. Should I wrap these stakes with burlap to keep salty snow about 3" away from the trunks? If so, should I stuff leaves or straw for extra protection? Mice: Should I put a vinyl spiral "tree guard" around each of the trunks, to keep any nibblers away? Thanks, in advance, for any guidance on this.
