THE STRINGFELLOW METHOD . 249 In all these trees, except the Myrobalau plumroots, the short-root pruning was a decided dis-advantage. Yet there is no contradicting the factthat others have obtained good results from it,and it has been put to a successful commercialtest. All this shows, as has been said (page 238),that stub-root pruning is to be considered a mat-ter of local practice, not a matter of generalprinciple. The practice may be good and it maynot: the explanation or assumed theory is will probably be found to be best adapted tothe South, where plants grow
