what is the spread of a tree
Tree spread is simply how wide the trees branches eventually become (from one side of the tree strait thru the trunk to the other side).Acer palmatum 'Bloodgood' slowly grows to 20 feet wide so it will have 10 foot long branches on each side of the trunk (10+10=20 feet).n might mean radius in UK or all of Europe for some odd reason, but in the U.S. Spread means just that, the spread of a tree (the diameter measurement of a trees crown). I believe most or all nursers in the U.S. mean this also. 20 feet is the mature width (spread) of Acer palmatum 'Bloodgood', not 40 feet.
