us from hams Arborcare is master arborist Kevin Ham. Kevin,

(00:22):
how you doing this week?

Speaker 2 (00:24):
Very good, Sean.

Speaker 1 (00:25):
It's good to talk to you. We're going to talk
about a really cool project you've got going on and
get to bust out the air spade, which is a awesome,
awesome tool which I've seen video of you using it
and it just looks like a really neat, very useful tool,
but a really neat one as well. We're gonna talk
about that in just a moment. But I had asked
you because I've noticed a lot of limbs coming down,

(00:46):
and obviously there have been storms and other things which
may have cost some, but it looked like a couple
of these that I've noticed, Kevin, were just kind of
like random limbs that whether it was rain or heat
or something, just kind of randomly dropped off of trees
and you had replied with a term that I hadn't heard,
which is summer branch drop. What exactly is going on there, Kevin.

Speaker 2 (01:08):
Yeah, it's it's a phenomenon that occurs usually on hot
days where you know you're getting a lot of expansion
in congection with with the temperatures, and it creates a
crack between the tension and compression wood on a long limb.
So you usually have it's a long extended limb, and

(01:31):
and you know on the bottom side of the limb
you have compression wood right the weight of the limb
is bending the bend ratio is compressing the wood on
the bottom, and on the top of tension wood that's
holding that branch up and in between almost right on
the pith. There's often a crack potential between those two

(01:53):
opposing forces, and and it'll happen on a hot day,
sometimes late in the year, when the temperature's coming back down,
and all of a sudden, that crack opens up right
in the middle of the limb, and then the way
that the limb drops, and and then it will fracture

(02:14):
just on the top side tension wood behind where it cracked,
uh literally, and it'll just the whole branch will will
drop and and yeah, summer branch shop for lesser turn.
But sometimes that will occur where that the crack will happen,
but that final break doesn't happen. Okay, sitting there waiting,

(02:38):
and then we get a heavy rain and that adds
a lot of weight to the branch just in the
surface tension of the water and boom a branch drop
and oh it wasn't even windy, it was just rain,
but it was predisposed.

Speaker 1 (02:52):
Potentially, is that something that can that that a transpection
can can show like a potential for. Is that something
that that you can that you can observe or is
that something that just can happen relatively in short order
where it's not really all that preventable.

Speaker 2 (03:09):
Yeah, we will do reduction cuts. You know, you can
make reduction cuts with rather small diameter, even two three
inches at the most, and you can take quite a
bit of weight off the end of a long extended branch.
And so oftentimes in really mature trees within you know,

(03:30):
an urban community where you've got a lot of human
activity and hazards are of concerns, we can look at
these and say, hey, that's a really long lamb. You know,
sometimes you've got a really majestic oak with these huge
sweeping limbs, and you don't want to change the architecture much,
but you can make some selective reduction cuts and lighten

(03:51):
that up and take that pressure off of that tension
and compression, you know, dynamic.

Speaker 1 (04:00):
It's interesting too, are there certain trees that are more
I always feel like silver maples get called out on
just about everything. A lot of the trees I noticed
was one, h Are there certain trees that are more
susceptible to that, to that summer branch drop.

Speaker 2 (04:16):
No, I've seen it across the spectrum, you know, uh,
from white oak, you know, which is fairly sturdy wood,
to you know, silver maples, mulberries, you know, tend to
have a lot of poor branch structure. And so you
also have the quintessential included bark union that is is

(04:40):
a very vertical union and and and there's no real
graph there. Those tend to break out. And in fact,
in Portage, where we recently had a bunch of storm damage,
the wind was out of the northwest in August, which
I didn't go back and look at the record, but
it could have been decades and a northwest wind arrived

(05:02):
in August in this particular area, and so that's not
a common way that trees are being pressured. And then
all of a sudden, this big force comes out of
an odd direction and all these unions that are kind
of predisposed and they don't have a bunch of reaction
would built up because trees will put on reaction would

(05:25):
where there's stress, and so kind of cycles of stress
will increase the growth of wood. It's pretty phenomenal that
trees can figure that out. Yeah, but you know when
an odd wind comes, you know once in a couple decades,
then a bunch of these trees break.

Speaker 1 (05:47):
With that stuff too. Then, Kevin, as we talk about
whether it's whether it's from bizarre wind patterns, I know
you guys do a lot of kind of that northern
edge that Lodi Portage, Fox Lake area. And of course,
if you can hear our voice, whether north southeast or west,
heaven and Ham's arborcare is there for you, whether it's
whether it's that kind of unique circumstance involving wind. Obviously, storms, rain, heat,

(06:08):
those type of things. It's really important to if you're
seeing issues or have concerns, questions or if you lose
a limb to really have that taken care of properly.
Is having that kind of aside from being unsightly, that
can lead to more damage to the tree, can't it?

Speaker 2 (06:23):
Yeah? Absolutely. And sometimes you'll see these these tension compression cracks.
You'll look up and you go, oh, there's a crack
right down the middle of that lift look at that.
And that was a summer branch drop that only partially completed.
And sometimes you know, you'll come across the situation where
five years ago that occurred and there's reaction would all

(06:44):
around it, and you think, well, I guess that's that
branch is gonna make it. You know, we can probably
leave that will lighten up the end a little bit
too to help it out. But yeah, trees, if they're
left long enough so recover. But you can oftentimes find
a cracked limb like that.

Speaker 1 (07:06):
What about as we talked this morning with Kevin Ham
of Hams Arborcare and some of the seasonal stuff going on.
Great day to get on the schedule, I got to
just pick up phone, gave a call eight six six
five nine six five three nine six that's eight six
six five nine six five three nine six, whether you've
got storm damage or you just haven't had your trees
checked out and cared for recently. Definitely want to get
on the schedule with Kevin and the folks at Hams Arborcare.

(07:28):
A couple of years ago, I remember the first time
you and I had talked about the airspacedoel, I had
to google and see what it looked like, and then conveniently,
I think, actually the conversation you had, you had to
then posted a video as well of one and use
a really cool tool but also a very useful tool
when it comes to taking care of taking care of
trees and their roots. You've you've had that one out recently,

(07:49):
and you've been working on a on an oak tree,
haven't you, Kevin.

Speaker 2 (07:53):
Yeah, well, Eli came across one yesterday or the day before,
large old tree, you know, forty inch diameter or something
like that, big red o. And there is a time
of year where some mushrooms will grow, you know, they'll
pop up in a couple of days, and all along
the base on the backside of the lean it leans

(08:15):
towards the house, all these mushroom conks showed up and
that's indicative of decay. And so it's a you know,
big valuable tree. So they don't just want to say, oh,
I just cut it down, because sometimes these conks can
be connected to a very small pocket of decay. But

(08:36):
we're going to just as a precaution, this is probably
not a favorable situation. But we're going to blow it out.
And so we can move the dirt out from the
base of the tree and see where those mushroom conks
originate and what what is the extent of the decay.
And we also have a sounding device where I can

(08:57):
run a sound signal through the tree and I can say,
is this a solid oak tree? Or if the sound
takes longer to go through, then we know it's less
dense and there's it's being slowed down. You know, a
solid dense tree, the sound moves fastest through that wood,

(09:20):
but if you have soft, punky woods, it'll slow it
down quite a bit. Wow. And these are micro nano
seconds that we're measuring, right, But it's a nice little
school that it doesn't it's not like the fancy ones
that they can print out a sheet that show the
inside of the tree. You can get those two those

(09:41):
are about twelve thousand dollars. Wow. But this was a
little more friendly on the price point. And it's a
single pole, so we just have to move it around
the tree and get different readings and I can kind
of visually see, you know, Okay, the pop it's probably
on this side. You know, I've got solid wood over here,

(10:03):
but it's not over here, and so we're going to
be doing that. I'll probably film that to get a
fun on the channels. Oh, that'll be it'd be good information.

Speaker 1 (10:15):
Yeah, that'll be awesome. You mentioned those channels. Of course,
make sure you're following Ham's Arborcare Game of Trees on
their YouTube channel. Very very popular destination, great content. A
lot of folks are checking those videos out. You can
do that as well. Of course. Also you can find
Kevin and everyone Game of Trees on their Instagram videos
as well the website Hamsarborcare dot com. That's h a

(10:38):
five nine six five three nine six Kevin, it's always
fun talking with you, my friend. You enjoyed this great
day and we'll do it all again real soon.

Speaker 2 (10:45):
Thank you. Sean.
