We live on 1.5 acres in the Spokane Valley.  We have lived here 35 years.  For the most part we have kept the place free of toxic chemicals.  We have three 60 year old apple trees, two 60 year old sweet cherry trees, and a lovely, old plum tree.  The fruit on that tree is like honey, no bitterness under the skin.  There is also a 25 year old Black Walnut that produces a lot of nuts.  We just have to figure out how to liberate the nut meats from the outer hull.  Our rhubarb, raspberries and horseradish are well established.  All the other fruit bearing trees are 10 years old and younger.
