Prim, it's a shame that those trees will have to be cut down and wasted in a couple more years. There was a house not far from us with a front yard planted like an orchard. Trees in nice straight rows and several rows across the yard and it was a relatively small front yard. From what I could tell just driving by every tree was different and they were planted less than three feet apart. The house went up for sale and the new owner removed probably 90% of the trees, leaving them seperated so they could grow.
