I have a 50 acre porperty in the Owen Sound area that previously was a grazing pasture. There is ~60 mature maple trees (sugar and black) in the centre of the acerage. Unfortunately, the previous owner allowed the cattle to pasture amongst the trees, and as such, all of the undergrowth and seedling have been completely trampled. I am intersted in planting sugar maples and extending the size of the treed area by ~ 1acre per year. I am interested in finding out how to start the sugar maples from keys - i.e. When to collect, where to collect from (existing trees vs local variety), how to plant, bet way to ensure success. Any help or comments would be appreciated.
