Re root sprouts:  Soil type or other conditions could make a difference. 
If you cut through the roots of a plum some distance from the tree, you will 
tend to get sprouts where they were cut.  My sweet cherries make a few 
sprouts some 10-15 feet from the tree, but there is quite a cluster of 
sprouts in one area, where the cherry roots come up against the root zone of 
a large oak.  I haven't been digging there, so I think the oak has something 
to do with it.    Donna
