Last fall, we had 20 or so 5' arborvitae planted by our gardening guy. They
browned up some during the winter, but pretty much came back over the
summer. Now they are all browning out from the center. It looks pretty
widespread and there is a lot of browning going on. Are we going to lose
them? I hope not - it was a lot of $$$ to plant them in the first place. The
gardening guy says we need to water them - which we are doing, but it looks
pretty bad. Any advice or anything? We live on Long Island, NY.
We planted arborvitaes because we thought they were fairly hardy and easy to
care for. It seems to me they are awfully finicky. We should have gone with
They are very hardy and easy to care for, but there are a number of
variables involved. First, where you got the plants, how big they were and
how they were delivered (containerized or B&B). Arborvitaes are a dime a
dozen but how they are grown by the grower and how they are harvested and
delivered will have a lot to do with their long term viability. It pays to
get good ones, not those offered by the box stores which have ridulously
small root balls for their size and are often allowed to dry out.. Second,
planting care is important - wide, shallow, unamended holes in well-draining
soil. And they will need water to get established, specially during hot
summers or dry falls and winters - 1" per week at a minimum. I suspect lack
of sufficient watering (or conversely, TOO much) may be the problem
Hemlock would have required exactly the same considerations. Plus, they are
subject to damage by adelgids in the Northeast.

I found a Web site that states that browning from the center out in
arbrovitaes is a normal occurence in the fall and not to worry.
in the 4th paragraph. This is from the state of Virginia, but I've seen the
same page elsewhere too.
The ones we bought were 5-6 feet tall and the gardener bought them from a
wholesaler somewhere. Not from a box store. The ones we have were planted a
year ago (fall 2003) by the gardener. I wasn't home, but I assumed he
planted them correctly. I don't know if a year is enough to be considered
"established" or not.
With all the browning that arborvitaes seem to do, they are emotionally
dificult to have. I didn't expect them to be such drama queens. I wish
they'd just sit there nice and green all year like hemlocks, although true -
hemlocks do get adelgids.
Establishing will typically take two to three growing seasons for a woody
plant. Yes, some interior browing of foliage in fall or winter is common
with arbs (and a number of other conifers, too) but I got the impression
from your post this was rather extensive. Once they thicken up this should
not be very noticeable.
"Drama queens"! First time I've heard them referred to as that :-)

I apologize if i am misreading you, but you say "browning out from the
center". What is the exterior layer of foliage like? Healthy green or
brown? Inside of that exterior foliage towards the center is normal to be
brown when you have thick exterior foliage. All of mine are brown towards
the center and lush green on the exterior and they are growing like bonzos
-- to the extent that arbor vitae can. ;-)
All summer they seemed to be green all the way. Now that it is fall, the
interior is browning up. The outside still is green. I wouldn't say the
exterior is "thick" - the plants are only 5-6 ft. tall and aren't that thick
to begin with. I'm hoping that this is a normal annual fall thing with
arborvitaes that as a new arborvitae owner I'm learning about. I hope. The
didn't really put on all that much height this year, but maybe that is
because they just got planted last fall and are getting established.
Arborvitae are now shedding their inner foliage. Just as white pines are
dropping older needles. At least here is pa.
Beings its from the center it makes me think you are just seeing shedding.
Much more on trees:
Bob, I can't help with your problem but share the exact same situation. Not only did they start to brown significantly in the centers but didn't stop there. Out of 16 planted, one died outright from root borer, 6 others lost rear half (probably planted too close to house), 6 others have half the stems dead. Only 3 are doing well!
This is after 4 years, bought from a nursery with large root burlapped balls, all planted in same type soil, fertilized each spring and watered regularly via drip irrigation. And all in a forest setting loaded with very healthy hemlocks and native cedars (Quebec zone 4b) .
I agree with you: I find them extremely finicky. My term for mine now is "ugly queens".
I just hope they will adapt longterm, fill out and become just plain "Queens"!
Anyone with suggestions on acheiving this long term hope?
Will they fill out eventually if I cut out dead stems? Any special care tips?
The fact that you live on Long Island makes me nervous, because I too live here
and I see how some of the so-called "gardening guys" treat plants.
The crews here are big on weed-killer -- did they apply any near the young
arbors? Also, they are big on "working" the soil at the base of trees and
shrubs -- constantly digging and piling up soil at the base of stems because it
may look asthetically pleasing, but it basically tortures the young roots and
doesn't let them catch on.
I've also seen rows of browning arborvitaes along dry, windswept curbs and
high mounds, without any sort of mulch or adding of organic matter to the poor
dry soil. In what conditions are your arbors planted?
Well what do you expect? Al the Long Island "gardeners" are nothing but High
