Re: tsuga

Thanks for your input. I may just give it one more try! At least we don't have the wooly adelgid around here! Snow, we have, with another 1-3 inches due late tonight.

Interesting discussion about hemlocks.  Here, they need to be planted
in some shade, or at least protection from the hottest afternoon sun.
 I would imagine they can take more sun farther north; most plants
can.  The other thing about this tree is that it does need soil that
does not dry out but drains well.  I assume that need prevails no
matter where they are grown.  They will grow fine in clay as long as
it drains well; they won't tolerate soggy soil nor a bone dry one.

They do not, however, want deep shade which causes branches to thin
and die out.  They need light and air if not direct sun.

One other note; they need an acid soil, so those of you in the
Midwest, who may have neutral to alkaline soils may have a bit of
difficulty keeping them happy.

The biggest problem with them is the hemlock Woolly Adelgid..nasty
pest responsible for death of major stands of Tsuga.  Hort. oil is
quite effective against this pest, but needs to be applied fairly
regularly once they appear and at the right time in their life cycle.

I have a Tsuga canadensis hedge that I planted as 3- 4' plants in
1987, as well as a weeping one that I planted at the same time as a
tiny tot and is finally beginning to make a lovely big mound.  I keep
the hedge more or less sheared  at about 6.5 feet tall and badly need
to be doing that right now, but with all this durn snow, I have not
been able to get at it...and it is snowing like mad right this
minute:-(  I have seen enough of this blasted white stuff!!!

I have read that Eastern Hemlock can be tempermental and that it
requires some shade, but I thought that since you and I are in
climate, they'd be easy for you. Mine have been planted in amended
soil and mulched. However, the ones on the Extension Office Grounds
planted in heavy clay, no protection, and seem to do just fine,
