First, it depends on where you live, e.g., if the ground freezes in winter
or not. If evergreens go into winter and haven't been adequately watered,
the bitter winter winds will dry out the "needles", which you won't notice
till things thaw in spring and you have a bunch of rusty red foliage.

A couple of other things -- most plants need 1" of rain or supplemental
water per week. Newly planted trees and shrubs shouldn't be fertilized
until they had enough time to establish enough of a root system to support
the above ground part of the plant. A general rule of thumb is to hold off
on fertilizer one year for every inch of trunk diameter.

Hope this helps!

I am now on my fourth replacement for two Arborvitae (Emerald Green),
and the
general pattern is that they grow for about one season and then start to
die. These
trees are on the West side of the house, but get at least a full half
day of sun. They
were planted correctly and well maintained with adequate water and
Miracle Grow
for evergreens. I'm beginning to suspect the nursery, although they
claim that over
the years, they have used several sources for trees. They usually come
bailed, and
we remove the wrapping for planting. There were formerly Red Cedars
growing in
these locations, one on either side of the house entrance, and they were
mature trees
when we moved in 20 years ago. We took out the Red Cedars about four
years ago
when they gave us problems with Apple Cedar Rust on our apple trees, but
the cedars
were always healthy looking, aside from the rust. It's a real puzzle
why these trees
keep dying. Since taking out the cedars, there are no signs of the
Apple Cedar Rust.
