Urban Collecting
Collecting yamadori in Delaware? I don’t think so. The highest
point in Delaware is 447.85 feet (135.5 meters) above sea level and the
lower two thirds of the state are about 10 feet (3 meters) above sea
level. While there are forest areas, it would be difficult to claim that
one is collecting trees from “the wild” in Delaware. Taking a more
“MidAtlantic” view, there are some more rugged territories in
Pennsylvania, Maryland and New Jersey, but the east coast does remain
relatively
urban. This
does not
mean that
there are no
good trees to
collect in the
area.
Where to
Collect
You may
think it
strange, but
one of the
better places to collect is in your next door neighbor’s yard – both
literally and figuratively. I do not mean midnight digging. It is
amazing to me how many neighbors pull out foundation plants, wanting
to redecorate their yard the same way one might redecorate the inside of
the house. All of my neighbors know that if they want anything
removed, they should call me first because I work for free if I am
interested. This works for several reasons.
If they are adding onto the house, they will almost certainly have to
remove some bedding plants.
Some older houses in
Wilmington, DE or on the
Philadelphia Main Line are
being torn down to make way
for newer construction or
multiple houses are being put
on big older lots. These always
require the removal of bedding
plants and some of those can be
quite old and nice. Try to stay
aware of those, or better yet, let
local nurserymen know that
you will take recently-removed
material off their hands.
One of my neighbors is a
convert to “native species” yet
Japanese maples keep
springing up in the woods
around her house. She used to
go around pulling them out of
the ground, but now she knows
that all she has to do is call me
and they will spontaneously
disappear. This is a case where
one has to do a very good job
of returning the floor of the
woods to a pristine state,
spreading the leaves around so
there is no evidence of
digging.
A neighbor had a nice old
juniper out by their mailbox. I
told them that I would be
happy to replace that “mangy
old thing” that had all sorts of
dead wood with a nice new
plant from the nursery. They were happy and so was I.
Sites being converted to commercial
use will often have useful material.
One has to watch the site carefully. I
had located some nice crab apples one
fall when I could see the size of the
apples. The next spring when I went
back to dig, the backhoe and the Bush-
hog had shown up. Some of the trees
were already reduced to chips. I got
permission to dig a few of the
remainders, but when the backhoe
operator saw how hard I was working,
he came over and dug them for me in a
matter of minutes. He was pleased that
they had been saved. When I said they
were for bonsai, he replied, “I didn’t
know bonsai grew here. I through those
were crab apples.”
Finally, a good place to collect is local nurseries, but I am not
talking about buying material. There are several old abandoned
nurseries in our area and there can be interesting material in the ground.
The other thing to watch is the junk pile of local garden stores and
nurseries. They will often have damaged material that they are
discarding because no one would buy it. But if the plant is alive and
has some low growth, it could be a nice starter.
Farms can be great locations to collect and it is relatively easy
to identify the farmer for permission. Trees along fence lines have
often been distressed by farming activity. Some trees in cattle pastures
have constantly pruned by grazing cattle.
Where Not to Collect
You will often see nice material along railroad tracks, particularly
when they are abandoned or seldom used. They would keep plants
along the side of the right-of-way trimmed. Unfortunately, it is
impossible to get permission to collect in these locations. And more
recently they have switched to chemical management of growth so
everything is dead.
Parks of any sort are off limits. They are there for the preservation
of plants and animals and despite any reasonable requests that you
might make, you will not get permission. Enforcement can be quite
strict.
One often sees very nice material along the sides of highways. This
is particularly true of crab apples in
the spring and fall, Virginia creeper
in the fall, and wisteria in the spring.
Conifers are best spotted in the
winter. State Departments of
Transportation are not in the
business of letting anyone do
anything in those right-of-ways.
Nonetheless, you can often spot
material just beyond the right-of-
way and get permission to enter
from the back side. If it is not clear
where the property line is, you might
accidentally collect something from
the highway.
It is possible to collect in
national forests but one must
obtain a permit from the US
Forestry Service and pay per tree
that you remove.
The Pine Barrens in southern
New Jersey would seem to be a
great source of pitch pines and
wonderful but rare pygmy pitch
pines. These trees make excellent
bonsaiand are often highly
contorted and stunted in nature.
There are two major issues with
trying to collect these trees. First,
the Pine Barrens are protected
habitat, so collecting is illegal.
Second, the poor, acidic sandy
soil means that a small tree will
have a huge root base and when collecting, it is almost impossible to
get enough feeder
roots to allow the tree
to survive.
The issue of the
Delaware sea shore is
similar. Collecting is
not legal, but in the
name of native
species, Delaware is in
the process of killing
or removing all of the
black pines that were
planted along the
dunes during World
War II. It is possible
to get permits to
collect these trees, but
in general, the shapes
are not conducive to
bonsai. There is also
the issue of very large
feed root systems in the sandy soil and most of the trees are infested
with nematodes that greatly reduce their lifetime.
What to Collect
There are many bonsaiable (is that a word?) trees available in the
Delaware area. Trees growing wild include crab apple and eastern red
cedar. If one knows anything about cedar apple rust, then you know
that these two trees doe not get along with each other. This fungal
infection can be disfiguring to both, yet they co-exist in this area. If
you have either in your collection then you will have infection issues
from the wild trees nearby, so there is no reason not to have both.
Sweet gum is almost a weed in the area and it would seem that the
leaves are too big for bonsai, but the leaves reduce very well and the
tress can be quite interesting. In the wild, sweet gum retain an almost
pyramidal shape for most of their lives, so if you are into the traditional
“left-branch, right-branch, back-branch and Apex” type of design they
lend themselves well.
Privet and willow are available in abundance, particularly in lower-
lying areas. Red or swamp maple (acer rubrum) are available and
easily spotted in the spring when their bright red budding foliage stand
out. Wild cherry is available as is persimmon, but both are difficult to
use as bonsai because they do not provide enough branching.
Somewhat out of the mainstream and on the listing of invasive
plants, one can find bittersweet, porcelain berry and honeysuckle.
These are vines but can be trained into interesting trees. The porcelain
berries are particularly showy in the fall after leaves have dropped.
Virginia creeper is easily sighted in the fall when it is crimson red. It
does not do well as a traditional bonsai, but can make a very showy
companion plant.
American Beech is an interesting problem. What appear to be
seedlings under more mature trees are often root suckers. If you start to
dig and find two roots 180 degrees apart, walk away. The small tree
will be on a very large horizontal root with no feeders anywhere in
sight. It should also be noted that the leaves on American Beech do not
reduce well and the intermodal distances can be pretty large. Thus, one
is usually better off to pass them by.
Having discussed the trees from the wild, I now turn to garden
plants. It is possible to locate some very old material around homes
and one should feel free to collect anything you can find after
considering the suitability for bonsai.
Much of the focus here has been on large trees for bonsai. It is
also possible to collect small trees that are quite nice. One club
member has shohin and mame trees that were collected from areas that
were mowed once a year. The stock can be quite old but it gets
chopped back rather callously every year. Thus the roots and short
trunk will have survived a quite difficult life with lots of scarring that
can make for good bonsai. Locations that get this treatment can be
along the edges of farmers' fields, maintained trails through fields and
forests, and perimeters of large parking lots that edge woods or natural
open space. Highway right-of-ways can also yield such materials, but
collecting is seldom permitted.
Does and Don’ts
Do ask permission to collect. Don’t get caught if you didn’t get
permission. Do talk fast and act dumb if you do get caught. Don’t cry
unless you think it will help. Do say you are sorry. Don’t be
belligerent - you are the one in trouble. Do try to take the trees you dug
because they will die otherwise.
Don’t collect during tick season because Lyme disease is rampant in
the area. Do wear protection even if you think there are no ticks. A)
Long pants tucked into boots. B) Long sleeve shirt even if it is hot (or
especially if it is hot because that is when they are active). C) Good
insect repellent. Do check yourself carefully during collecting and
when you are done.
Do learn what poison ivy looks like. Don’t think you won’t get it
anyway. (In early spring, I have dug leafless poison ivy in the root ball
of a crab apple. I went home and washed; then bare-rooted the tree.
The Result: a perfectly straight line of poison ivy across my hand where
I pulled on the root.)
Do get your tree home. Don’t be stupid about how much you can
carry. The bigger the tree you collected, the farther away the car will
move while you are digging. There is no tree worth hurting your back
for. Use a wheelbarrow or a teenager. They are as useful for carrying
the beer in as carrying the tree out. Do be sure the tree will fit in your
car - the bigger the tree you collected, smaller your car will be.
Tools
One of the best and newest tools for collecting trees is a GPS. It is
often easier to identify collectable trees at times when you might now
want to collect them. Simply record the location and you can get back
to it a year later. It also helps you find your way home if you get too
deep into the woods.
The most important tool is a good poaching shovel or poacher’s
spade. (So- named because it was the tool of choice for stealing rabbits
from the lord estate.) This is a long narrow shovel that is useful for
digging around a tree but also for cutting through roots. It is not as
long-handled as a garden shovel so it is easier to carry and the
perpendicular handles is useful when trying to lever out a troublesome
plant. Sharpening the blade can help with roots, but it is usually dulled
rather quickly by gravel and rocks.
Good hand-cutters and a collapsible garden saw are also useful. If
your walk is short, longer-handled loppers and a pruning saw are
useful. The saw should be an old one because you may well be sawing
under the tree trying to get thru a tap root and the stones will quickly
take to edge off any tool. When sawing thru dirt, you never know what
you are going to hit.
Of course, there are the necessary safety items like good leather
gloves and safety glasses. And some bug repellent. Wear good boots to
protect your feet and ankles; this is both for walking in/out and for
digging.
Finally, you will need some heavy trash bags or burlap and some
string to wrap up the root ball that you did and have to carry back to
your car. It is easier to dig and easier to carry your plants when the
ground is slightly dry, but you are likely to knock much of the dirt off
the root ball. If it is dry, also carry a mister of water to wet down the
edges of the root ball.
How to Dig
Dig wide around the base of the tree to be sure that you get plenty
of feeder roots. You should cut two circles around the tree and then
clear the dirt out of the resulting trench. This will allow you to better
see what you are digging from there on. Cut any troublesome side
roots with the lopper or saw. This is the point where you start the rock
and roll. Move the tree around to discover the root connections and cut
them one at a time. This should be the point at which you simply pick
up your tree, but it is never that easy. A tap root, if there is one, is
always the final problem. Use the saw to cur blindly under the tree
until it is free.
After it is Home
I almost always bare-root trees collected in Delaware to remove the
clay. When I collect bigger material I don’t have to carry as much dirt
back if I bare-root the tree on the spot. Bare-rooting allows you to see
what are real roots and what are weeds. If you do bare-root on site,
moisten the roots and protect them on the trip home. If it is a quick
trip, a plastic bag is enough, but remember that black plastic bags in the
sun are murder on roots so shade them. If there is a long drive (as
opposed to a long walk out it is better to leave the soil on.
Potting
Survival of the tree is the most important thing to consider. There is
no point in digging them if they are going to die. Bare-root the tree
now if you did not earlier. Get all the bugs and weeds out of the dirt
and see what you have.
Overpot. You don’t need to and should not do all of the root work
the first year. Planting deep means that it won’t dry out that first
critical year. Use a coarse soil with lots of Turface® to promote quick
root development
Mica pots are priced right for the size and they have the advantage
of looking like bonsai pots. Wooden boxes can be made any size. They
are inexpensive and biodegradable. Styrofoam boxes or plastic tubs
with adequate drainage are inexpensive but they look pretty bad.
Inexpensive mortar or cement mixing trays are available in the big box
stores and can work well if they are the right size for your tree.
The yew above was about 6 feet talll when collected. It was
cut back to 30 inches and is shown in the first picture a year
after collecting.
