I want to plant some dwarf fruit trees (plum, apricot, cherry, pear) but my soil is clay with about 6" good soil on top.
I can add about another 6" of good soil to the top in this area.
but below is solid clay, takes 2-3 days for a test hole to drain down.
What is my best approach for planting dwarf fruit trees in this area ? Raised beds ? how big ?
