I have often heard that thinning is always better than reducing, but have
not seen much evidence of this. It is repeated so often without scientific
or
any other support, I fear it has taken on mythic proportions.
Same here Guy, along with the idea that cutting branches off kills roots. If
this was absolutely the case then coppicing wouldn't work and it quite
plainly does, albeit not with all species of course.
Dunno what goes on in the US of A but round here the routine of pruning
street trees quite severely is, er, routine, sometimes quite severely. Do we
see
vast numbers of such trees dying? No. Some streets' trees round Sheffield UK
must be on their 5th or 6th cycle of crown reduction, and growing in quite
horrendous tarmac-surrounded conditions; still they survive, apparently
quite
happily. The occasional loss can usually be attributed to something other
than
over-pruning.
