I have seen Dwarf Alberta's get mites if they are planted too close to a
house.

Hi all -- I have two dwarf alberta spruces in full sun areas, one a
spiral topiary in a big container and the other a conical one planted
in the ground
in my front yard border bed. A couple of weeks ago, Adrian Higgins,
the gardening editor for the Washington Post, said in one of his
columns that alberta spruces planted in full sun run a high risk of
infestation from some
kind of mites (I can't remember what kind though). I'm wondering if
anyone
here has had that experience? I'm trying to figure out if I should
move my
albertas to a shadier spot to avoid damage to the trees.

Thanks,

This article says that they can be victims of red spider mites..these
mites are extremely common.
The best contol is to hit the folliage everyday with a hard hose
spray. They are very small and this
is a non invasive control that works.

My experience has been that Dwarf Alberta Spruce, being a native to
mountainous high altitude areas with excellent drainage, can suffer in our
humid, sweltering summers here in the Midatlantic Zone 7. If one can
create
a suitable climate (good ventilation, excellent drainage, frequent misting
of foliage, acidic soil) then they do much better.
