Re: [nafex] Tree guards for borers

["del stubbs" <pinewoodel@hotmail.com>]

	Michael, I'm not up to speed yet on tree borers yet.....but I guess it's a 
reason toward window screen - over say 1/4" 'hardware cloth'  (besides the 
price difference).
	How big are these little buggers?
	It seems to me the joint where the screen edges join would have to be 
nearly perfect, so one should overlap the joint before stapling instead of 
just wrapping the screen around the tree and tying with twine (as i 
suggested). This would make a more open tube, which would avoid the close 
bark contact that Steve just warned against.
	But, how does one seal the top, you mentioned spring staples...I don't know 
the term.
	Is burying the screen say 2" deep - enough to keep out any vole, tree borer 
or other life forms looking for dessert?
	Is the 3" diameter screen tube a proper choice of size?...that is, is a 3" 
dia tree of the age ready to have it taken off and not be instantly devoured 
by the awaiting minnions.....?
	Tree borers...anyone know of a web site with pretty macro pictures of the 
little monsters and the fun they have?   Mn Del  (Where it was just 24 below 
and we're not transplanting any pears!)
