Subject: container grown trees

I used to think that container grown trees were the next best  thing since
shirt pockets. In recent years I have seen so many root & tree  health problems
developing as this type of tree has filled the  market.

I too, used to be impressed by the fine root mass that was  developed... no
more!

This mass of roots may be good, for the grower, when the  trees are under
irrigation at the nursery but it has become to be apparent that  the development
of  major lateral roots that form the stability of  trees as they age, has
been shut down.

As roots hit the walls of containers, and yes... root fabrics,  too... their
natural radial growth is essentially stopped...one or more of  the tropisms
may be a interrupted. The results are often a brillo pad  of roots that do not
move laterally in the normal fashion, aggressively  explore and provide strong
anchorage. Let this fine root mass get dry at the  planting location and a
quick death will result.... there is no water-holding  capacity in the woody root
mass and the bark/sand "soil mix". This is akin to  attempting to wetting of
peat moss when it dries out.

Dr. Ed Gillman, researcher with the University of Florida,  told me that most
of the trees that were lost in recent hurricanes had  been container grown
trees... lacking sufficient lateral  anchorage.

Perhaps the most pervasive problem with container grown trees  is that the
trees are set too deeply in the containers thereby burying the root  flares.
This situation eventually leads to massive girdling of the trunk and  root flares
and we often find that this situation cannot be corrected by root  flare
exposure and removal of the girdling roots... a very costly remedial  process.

Currently, I am in the process of removing a root mass from a  Loblolly Pine
in a 45 gallon container in order to find the root flares. So far,  I have
removed a 6 inch profile from a root mass depth of 16 inches and no root  flares,
yet. I am beginning to have strong reservations about planting  this tree,
where is may eventually fall on my office... aaarrgghh!

Root flares... are an indicator of the natural grade of the  tree.

The majority of my tree diagnostic calls relate to the burial  of root flares
which leads to stunting of growth, canopy thinning and varying  levels of
decay of the trunk tissues above the root flares... sometimes, very  scary loss
of structural strength in large trees caused by trunk decay and  death of large
lateral roots.

Container trees? I will stick with shirt pockets!

I love growing trees too.  I usually start with  bare root stock, but I
have been experimenting with growing Hickory from  seed.  Hickory is
absent from the commercial market because of the  taproot, but I am
having success with a fiber pot from Rootmaker. I am  fortunate for
this hobby to be part of my job.  Below are the trees  currently in my
nursery.  The Rootmaker pots, www.rootmaker.com   ,I use don't allow
the roots to circle.  You get a nice fibrous root  system, even with
tap rooted trees.  In a five gallon rootmaker pot,  you can grow a tree
to 1" caliper.  There is little to no transplant  shock too.  I use a
Fafard nursery mix that is mostly bark with a  little peat.  The plants
love it.  One of the best places to get  oddball native plants is
Woodlanders in Aiken SC.   www.woodlanders.net   they are mail order
and retail.  This  does not include the hundreds of trees we have
planted out in the  gardens.  I hope to live a long life so I can see
the trees  mature.  That is the neat part about planting trees, you
really don't  do it for yourself.  People that aren't even born yet
will be the ones  to appreciate the trees the most.

Subject: Re: container grown trees
I have planted trees for many years and have never liked container
grown plants. I much prefer bare-root because I want to make sure the
roots are spread out from the tree in a natural fashion, not the
kinked, circling mess you can so often have with container stock.

Give me a younger, smaller seedling, let it be planted properly and at
the right time, mulch it properly and give it extra attention the
first couple of years and it will generally catch up to and pass a
larger container plant of the same species within a few years.

As an example, I planted a small grove of longleaf pine seedlings bare-
root in 1/95, babied them the first two growing seasons with regular
watering and a very light compost tea, and in 8/96 they first broke
the "grass stage" that longleaf are known for, with a small amount of
terminal growth. Beginning with the growing season of '97, they all
skyrocketed in growth and the tallest are now closing in on 40', and
several of them had their first seed cones last year.

Direct seeding, therefore never transplanting at all, can be the best
method of all, but you've really got to protect that little plant when
it first pops up.

Gary and Sandy,  Writing your names I couldn't help wanting to write
Spongebob, Patrick, and Squidward too (all characters from a cartoon
my kids used to watch)

I very much prefer to direct seed, or plant bare root when I can.
Unfortunately, with the amount of deer and lack of labor, I have to
resort to other methods.  Black plastic pots are out due to girdling,
and I don't have the resources to field grow.  The rootmaker pots are
a happy medium.   It is much easier to water, feed, and monitor (IPM)
the young ones while in a group near the water source.  I plant a
little high if not at grade, and agree that this is one of the most
common oversights in planting.  Some times I have to add soil to the
pots because it settled, or I planted too high to begin with.  So many
trees come from the nursery to deep in the ball or J-rooted.  Often
these trees appear to have broken balls, but when you pull the dirt
off the top of the ball you find  the flare way down inside, up to 8"
sometimes.

The manager before me had planted a 4" Blue Atlas Cedar a few years
before I came along.  It was grown in a black plastic pot.  When I
looked at the tree a couple of years later, it was about 6" caliper
and I could move it back and forth in the ground!  I figured it would
topple at some point, and left it go.  (No need to put extra effort
into a non native)  After two additional years the tree is now about
8" caliper and is very sturdy?!?  I wonder if the potted trees can
overcome their beginnings with time.  It seems so in this case.

The biggest help with the fabric pots is the lack of transplant shock
when set out in the landscape.  A plant grown in a black plastic pot
will need almost daily watering when set out, whereas the rootmaker
grown plants seem to need very little water.  This is a big help to
me, with my small staff.  I guess only time will tell in reference to
the anchor root issue.

ENTS,
There is nothing wrong with container grown trees, as long as they are
planted properly---one needs to vigorously score or cut, with pruners or
even loppers if necessary, any encircling roots--this will encourage new
roots to grow beyond the root zone defined by the container. People are
simply too gentle when planting.

Burying the root flare(actually the trunk flare) is more of a problem with
field grown trees, since spading the rows for weed control throws soil on
top of the root zones.

I agree with you that trees do not have a root flare.  I was taught that pot grown is OK.  However pot put is bad.

A few things about this come to mind:

- With container grown tree, it is easier to hide problems then with
bare-root or direct seeding. Now, we Ents may see the problems
(hopefully, before we buy the tree!), but the average person won't
know any better since tree biology, growth, etc. is not their field of
study. They buy a tree in a container and expect it to grow, and when
it doesn't, they are very disappointed. General lack of knowledge of
trees also leads to things like: mulch volcanoes, planting trees too
deeply, etc.
- With a container grown tree, it is easier to just leave the tree in
the pot too long since tree is still growing (even if it is growing in
a way that will later produce problems.) This is "great" from the
viewpoint of a store just selling trees in pots - less turnover of
stock, etc. But it can make for a lot of problems down the road, as we
all know.

So, perhaps it isn't the containers themselves, though they are less
than ideal, but what the containers often lead to that is the problem.

Matthew,

My brother bought a house in Illinois several years ago and wanted to plant
a tree in the barren front yard. Both being trained arborists, we knew of
the dangers of potted trees and structural issues. So when we went to the
nursery to purchase a tree we intentionally picked the absolute worst tree
we could find. Our thought was that we could "save" the tree from an
ignorant homeowner and avoid its potential short life span due to
uncorrected structural and cultural issues. The tree we selected, a red bud,
was the "poster child" of cultural ignorance; crossing limbs, bad forks, and
redundant limbs. I think we may have gotten a discount after pointing out
the structural nightmare it was.

He ended up selling the house, but returned a few years later and was able
to climb the tree and perform a gratuitous conscientious pruning, including
pruning the growth away from the house as it had grown so fast!

It was a very satisfying "project" and we felt we had made a small, but
significant impact on the urban landscape. But we wanted more. So we also
performed "guerrilla pruning" where we would go into a park at night and
perform much needed structural (corrective) pruning on newly planted and
smaller, established trees. One night, we "hit" a park and generated a huge
amount of debris. The trees were in bad shape and in need of serious
pruning. Not wanting to leave the debris on the ground in disarray and
attract negative attention, we ended up dragging ALL of the brush to the
street and stacking it neatly. The next day the city came by and hauled it
away! Another success story!

John-

Unfortunately, bare-root trees no longer have much of a market, and honestly
haven't had for the past 50 years or more.  I'm not saying they aren't a
better way to produce a tree, but they definitely are less marketable to
consumers. And direct-seeded trees are completely unknown to consumers.

The plants currently produced by the nursery industry; container grown,
field potted, or B&B, are consistently of much better quality than 20 years
ago. Mulch volcanoes, like the similarly contrived mounded beds, will(I
hope) pass, as consumers realize they are just a fashion and become more
aware of what is needed for a successful landscape.

Here is a source for some native bare-root trees.  I do not see how you can plant a bare root tree at the correct depth (where the roots come off the trunk) without staking it.  Wire in a hose is torture.  I have one product I push - CAMB GUARDS for staking trees correctly.

The key for me in bare-root transplanting is that I want a seedling,
not a sapling.

That kind of transplant doesn't require some elaborate manner of
staking. I generally do stake, but with a very thin, but strong stake
very close to the seedling on the north side. The tree is tied to
allow it a little flex with the wind. The stake is going to be pulled
straight up out of the ground once the little tree is well rooted, the
soil where the stake was tamped down a little, and we have no harm, no
foul. Most stakes can be pulled after the first growing season. All
this may not be according to the book, but it has worked for me.

I've had some bare-root deciduous seedling transplants become
beautiful trees in a relatively short time if they were treated right
from the beginning, correct soil depth when planting, a  very slight
basin to hold moisture the first year, roots spread out naturally, no
air pockets, elimination of competition in a 3-4' circle, pine needle
mulching, and so on.

Containerized longleaf are one year old seedlings same as bare root,
but the survival rate is head and shoulders over bareroot LL. Bare
root works great for other species, but not LL. With Bareroot LL
Machine planting is a necessity and then if you do everything else
exactly right you may get halfway decent survival. Bareroot needs to
be planted the same day or the very shortly after they are lifted from
the nursery bed. The Forest service when they replanted with bareroot
would lift the seedlings in the AM and put them in the groud that PM.
They also have large/long roots that have to be properly placed in the
planting trench or you have a dead or worthless seedling. It is worth
the extra cost for containerized LL seedlings.

Containerized LL pines are actually plugs of seed medium about six-
seven inches long and about one inch in diameter. They still have to
be planted to an exacting depth, but you have time on your side. And
you can do it with a modified dibble that opens and exact size hole
that the containerized seedling fits into at the proper depth.
Containerized seedings also tend to come out of the grass stage sooner
that bareroot an important consideration with the competition out
there and also brownspot disease.

Will,

I've talked to the Longleaf Alliance recently, and they promptly sent
me a very nice packet of information concerning longleafs.

Also, even though I'm a "bare-root guy" for trees I've planted in my
yard, I have done some research and agree with your thoughts on
containerized longleafs for larger plantings. (I did have very good
luck with a very small group of longleafs I planted bare-root in 1995,
but they received some real TLC from me in the first two years)

I'm sure you know of International Forestry out of GA. I have placed
an order for containerized longleafs with them, which will be planted
in late 2008, Nov or Dec. The seed source for my longleafs is
Mississippi, which is where I'm at.

Thanks for your advice.

Gary

Hi Gary and others,

Have you ever thought about using rpm stock as an alternative to
seedlings and, I believe, outside of the stereotypes of
container-grown stock? I use their plants, always from native stock,
religiously, on all reforestation and creation projects. Check them
out at http://www.rpmecosystems.com/. I can provide more contact info
if interested.

The RPM trees look to congested in the root balls to me, which would
allow for girling and other issues down the road.  I would actually
prefer the whimpy looking seedling in their comparison photo.

In my reforestation efforts I came to the conclusion that buying stock
to plant out was a waste of time.  The labor involved was too great.
At one point I was able to get a tractor trailer load of 2" caliper
trees from the local wholesale nursery at the end of the season for
$10 a piece, as they were spring dug, and had been written off.  Talk
about instant impact!

What I do now is let the field go for a couple of seasons without any
mowing.  I spray the invasive trees to cull them.  I leave invasive
shrubs, as the Eleagnus and multiflora rose provide habitat and food
for the critters, and will be mostly shaded out in the long run.
Usually in year two, there will be native tree seedlings popping up in
the field. White ash, Tulip poplar, maple, Black Walnut and some oak
and hickory. Before September, when the deer start to rub on trees, I
protect the new saplings.  I use the recycleable light blue tubes from
Forestry suppliers and UV coated fiberglass rods from Premier one
sheep supplies and protect the new seedlings from the deer.  I like
these products, beacause I can use them repeatedly.  I have found that
cutting a small section out of the bottom of the tube allows baby
bluebirds to escape when they fall in (they seem drawn to the tubes),
and it deters mice from building their condos inside the tubes (allows
snakes access I guess)  Each year I go into the field and remove
vines, tube new trees and remove tubes from dead trees.

In a nutshell, I am just protecting what nature is providing, which
speeds up succession.  This works in Pennsylvania because of the small
patches of older trees that are around that provide a seed source.

I have been using RPM trees for only a couple years now, but root
pruning method doesn't seem to exhibit any stability issues yet. If I
had not seen it with my own eyes, I would not believe it. I purchased
two red oaks, planted them last year and at 210-days, they each were
over 5' tall! A friend of mine visited the nurseryman, Mr. Lovelace,
who patented the rpm process. He showed me pictures of 5-yr old, 20'
tall oaks in mast! Travis

That is great you are getting local provenence seed source. That is
important in Longleaf. Another thing I've found very valuable in
Longleaf is the need for ripping if you have any clay or hardpans.
What I remember about the western gulf region is a lot of heavy soils
that may have been farmed in the past. You might want to check with
the county agent or local NRCS agent to see if plow pans or argillic
horizons (claypans) are a problem on your soils. If so rip the land to
about about 18 inches or more this spring so it can settle out over
the summer. If it has been recently farmed it will definitely help
survival and also result in better growth and less windthrow later on
down the road. Even on light sandy land, heavy logging equipment can
create traffic-pans that will turn a LL tap root. We used a 1/4" piece
of rebar sharpened on one end and pushed it in the ground to determine
the presence of a pan. It will go down easy and then get hard if there
is a pan. Most traffic or plow pans are within 18 inches of the
surface. The NRCS folks have a specialized probe they can use if you
can get them out there.

I'd have partially disagree about the lack of quality roots in a
container. The problem lies more with the grower's management of the
pot
than how the tree responds. Most container grown trees are left in
their pots too long and when finally potted up are slipped into the
next size
pot instead of one that is much larger which would allow the roots to
spread. We grow cuttimgs in 38 cell air-rooting trays then pot up into
3 gals rooting pots.
From 3's they go to 10 gal. usually within 4-6 months. from the 10 we
move to a 25 gal. Meshpot of our own design. see this link
http://tech.ph.groups.yahoo.com/group/Treefarmers/photos/view/826e?b=4.
The roots never circle, the tips spread out, and constantly add new
growth as the grow out into air, die back and go lateral. The minute
one of our trees get's planted in the ground they respond quicky with
wind roots and taproots if they need them.
Nursery Supply Accelerators, Rootmaker, RPM and our Meshpots all are
superior to conventional pots. That said if careful management of
conventional pots is done then they will be able to grow fairly decent
roots. Rooting pots are significantly better but cost a lot more
except for our Meshpots which are very low cost. Ren

Ren, ENTS

I completely agree.  The black plastic pots, even with the spray of
copper ?? in them are far more inferior that the air or fabric pots.
The expense is worth it to me because the tree doesn't die in 7-10
years from girdling itself.  If the tree is set properly in the pot
during every transplant, you will have a much more resilient tree in
the long run.  Another thing I have noticed...If you compare the
stunted growth of a ball and burlap tree to the regular growth of the
air/fabric pot trees, you will see that these newer pots are better
than B&B too.  Convincing the public to spend the extra dough, and
convincing them on the advantages will always be difficult.  Most
humans think in terms of minutes, not years or decades.

Scott,
We've found that washing a 1/3rd to 1/2 of the soil off of a B&B
before planting allows checking the top of the ball for girdling
roots fungus, and incorrect root growth plus for checking the planting
depth against the root flare and integrating the roots into the new
soil/mx faster.
We water the soil/mix as we add it back, to fill the pot or hole.
Using rooting pots with drip and compost teas we've doubled our growth
rate as compared
to B&B. The soil biology is the single most important factor in
growing healthy, non-chemical trees. Ren
