I'm guessing that they are some variety of arborvitae or chaemacyparis. Most
varieties are relatively slow-growing, so you don't really need to be
concerned about not very rapid growth. Many are also susceptible to
spider-mites and problems with winter burn. Both can cause areas of
browning. It's also quite common for much of the interior foliage to die and
fall to the ground. Unless all the leaves turn a dull green and there is no
fresh smell when you run your hands across the foliage, I don't think you
need to be too concerned. Usually in spring or summer, I attach a strong
spray attachment to my hose and try to knock off all the dead foliage.

They are facing South? Yes.
Are they browning out on the South side of the tree? Mostly just patches,
not really in a specific area.
Have there been any ice storms? Not really that I can remember.
Seen any Bagworms? No.
How far inward are they browning? Like I said, it's in a couple of
patches and maybe goes a few inches inward.

Any advise????
