- What are they? How bad are they? What can happen to the tree in the future? These are all decisions that we need to make when looking at a tree and deciding what needs to be done. The mistakes of past tree workers can haunt your trees and when you least expect it----- CRACK!
Hi Blair. This was a very interesting video! I really appreciate the seasoned accumulation of knowledge that you share in your videos. Anyone can tell that you really love your profession. Thanks so much for the work you put into sharing these videos with the community!
Thank you. Kind words
Thank you, Mr. Glenn, for your knowledge, passion, and generosity. (Viewer #12)
Cheers
It's really interesting to know the construction work was 1994 so we get a timescale on how long the decay has been going, these things don't go wrong straight away and customers are sometimes really happy with the idea of big cuts and take some convincing it's not a good idea.
I’m hoping that more people will share this video.
I could imagine what beautiful Oak forest it once was. Such a shame they could of kept some whole that were away from the house. So sad to see such chopped up trees All weak and dangerous. They should remove them all and start another tree forest with proper care and native choices. looks like you always have clients who have had been taken advantage of or thats exactly what they wanted and they got it. Now they arn't the one paying for it It's the life of all those majestic trees at the Mercy of humans. Thank You for all your knowledge and perseverence.
The trees will all decline as a result of a past bit of ignorance. I’m trying hard to teach understanding and respect for what a tree needs.
Who needs the study guide when you have Blair Glenn!!! Thank you, so much, for these videos!
You still need the study guide but hopefully, my efforts will make these issues clearer. I hope this video gets shared.
You say a good analysis of the tree with a flush cuts they cause calluses and wounds and they say not to cut a tree like that but what I see with all those flush cuts in the holes I don't think that tree's too strong to stand up to a strong wind or something thank you.
We had a lime tree in the middle of a field. It was badly damaged on one side, would think that a tractor had scraped along it. Over several years, maybe 10/12 years, it hollowed right out. One side of the trunk, consisting of just bark, continued to produce enough goodness for a single branch to continue to leaf every year.
After about 20 years it finally fell in a storm
The deliberate tree decisions we make can be the difference between a thriving tree and a declining tree. In your case, an accident.
"you wanna know how I got these scars" said the tree 😂
Flush cuts bad, R.i.p. tree
Fatal flaw
Those Live Oaks look like really cool climbs... thanks for sharing that one Blair. I often wonder about large cuts near the base of an old tree, whether it's a flush cut or not... they can quite often lead to significant decay in my experience... Cheers my friend - Patrick
Always appreciate your comments Patrick. West coast trees do grow very different from your part of the world. We rarely ever get a frost but drought is a big factor in creating weakened root systems. Couple that with poor past harsh cuts and a lot of trees are real ticking time bombs! Condemned yet another big oak yesterday. Too dangerous to climb without being tied in to another higher tree. We got the job😳
Nice to hear the voice of experience and see tye root crown explorations. Your assessment of the viability and structural stability of the trees is likely spot on, and clear communication with the homeowner about their tolerance for risk and desire to preserve the trees is crucial. You did mention the importance of species and associated risk with the alder but never with the oaks. That's a crucial factor. You also seem to gocus always on the flush cut and never once mention the size of the cut, which refkects a 1980s mentality and would might mislead the uneducated into thinking that cuts of that size are ok as long as they are made with lroper target cuts. And while you did a good job of explaining the balance between taking weight off a structurally compromised tree vs removing so much foliage that the tree becomes too weak to survive, you fail to mention the benefits of reducing the large limbs in the canopy rather than removing them as the video implies you intend to do. Thereby creating even more large wounds on the main stem for the tree to compartmentalize.
In many ways your experience works both for and against you... stuck on the old shigo paradigm of target pruning, while also having a good sense of wgen a tree needs to come down
I generally stress not to make large cuts unless there is a good reason. (Decay, vehicle clearance etc.) I have a LOT of videos
@@arboristBlairGlenn but you didn't mention it once here... you didn't mention leaving a stub, or reducing rather than removing limbs, but you did titled the video flush cuts and must have spoken the word flush cut a dozen or two times here. That's 1980s mentality... you just don't recognize that about yourself.
Many urban trees in the UK are like this.
Sad but true
I wish this was more common knowledge than what it is.
It takes the effort of looking and seeing clearly .--which most people these days don’t understand.
That’s exactly what he’s doing, so hopefully, the next time someone googles proper tree pruning, this video will pop up.
An X-ray machine for these trees sounds like a beautiful idea!
Detecting decay under the bark is still a very primitive science.
Seems like there are some promising papers regarding the use of ultrasound (piezoelectric transducers) to detect decay in trees. I understand the tech works well in my industry (mechanical engineering) and would be eager to see if it translates well to wood.
I love your videos great teaching it's so hard to find a good teacher👌🇺🇲
Thank you. There are a LOT of them to watch!😊
Your welcome please keep making them Thanks 😊 You're the one that inspired me to start climbing been climbing 2 years now I love it
@@robertbrown9237 honored, thanks
behind the wounds s dead wood - the tree grows over the deadwood and uses it as integrity
Best wishes.😁
Thanks Shane. Back at ya!
Interesting how this is so different than apple trees. I started cutting to the collar and it heals completely over in a year. In two, you can barely tell there was ever anything there.
To the edge of the collar or close to the trunk. Apple trees also decay badly from poor pruning wounds.
@@arboristBlairGlenn wish I could just post a picture, but I learned of the idea from Paul Gautschi, the back to eden garden guy up in the PNW. I take a lot of what he says with a grain of salt, but this has worked for me. I may try to post a brief video showing my cuts.
@@arboristBlairGlenn Paul says the Creator told him to cut to the line, so he does. He sees pruning as much art as science, and seems to be very much influenced by Japanese ways of pruning. He always prunes to an extreme open center.
some of the rotting wounds are in a position that can retain weatherazation
this rotting occured because there was too many wounds in the same area - even if they were cut with a node left behind ! that many wounds would still result in failure , to much through out the system to heal that many wounds - opinion
12:30 I wonder if an ultra sound machine could be adapted for examining trees.
There is a machine called a Tomograph. Nails are put into the trunk with wires to a laptop. Each nail is tapped with a hammer and the program measures the sound wave from one side to the opposite nail. Weaknesses and hollows show a different type of imagery. Very expensive machine.
What a shame. Simple mistakes and now it’s irreversible damage! With the exception of Blair the tree whisperer. If trees could talk, they wouldn’t have to suffer this kind of abuse.
The “Tree Whisperer”, thanks.
Good video as allways. Love your videos on tree cuttings. I could show you some quite severe cuttings here done by the city. It leads to the questions: Are there any good examples of tree cuts, which turns out positive 20 -30 years on?
And in case, are there any good time of the year to do cuts?
BTW: @8:00 -8:20 Are there stress fractures on the pressure side of the tree base?
There are species of tree that do better than others. I often cut open old would on removals to see what happened.
My neighbour's garden has a bunch of trees and whe a gardening team cut a limb of and they actually used a axe to make it level with the tree trunk and i was wach this video when it was happingg
So now you can become the instructor.
I do not see any root flares in those trees. It's as if fill was brought in when the area was developed. When the trees come out of the ground like telephone poles it makes you wonder about fill. If that were my property I would remove all the trees you showed and replant with a variety of trees. When oak wilt hits, it wipes out the live oaks and those trees don't have any health to fight.
In my area, city permits are required for removals so there is an added difficulty.
live oaks are fire tolerant, should you burn off the ivy that grows on them in order to save them?
No fire
if you reducce a large amount of weight from those trees based onn your judgement ! you are taking away food supply that is needed for those wounds to heal roookie
You call me “rookie”. Better start with how wounds “heal”. They surround the wound with new growth but don’t heal. Read the work of Dr. Alex Shigo. As for weight reduction decisions, I’m cleaning up broken limbs everywhere right now. We make the call based on how to read the tree. This is my fiftieth year in business and I still climb daily. Except today, snowed in!!👍🏻
Blair, if you are stubbing one on a vertical, do you cut it level, or on an angle for run off? (Does it matter?)
That has been theorized for a long time. In what I have seen, does not appear to make much difference. A wound decays. Will an angled cut decay less aggressively? I don’t believe so but I may be wrong. Need data.
Where the oak trees are around the house is it the same house where the deadly alder was and the broken braford pear are and were
I saw the rest of the video it is the same home
Very good observation! I like it when you pay attention
So, what would have been the proper method to remove some of those limbs?
Retain the branch bark ridge (branch collar) and don’t compromise the tree’s ability to wall off decay. Study Shigo’s work. Dr Alex Shigo
@@arboristBlairGlenn thank you.

Those large 8-16inch leads should not have been removed. Probably could have been thinned/lifted with 2-4” cuts, to achieve a feeling of space and light if needed. Frustrating, Blair, to have to assess such a mess 😬
these wounds are not older than 2-3 years old
I received an email saying that this video was too long. Was it too long?
I didn't think it was. Don't let one person's short-sighted opinion affect how long you make the videos.
It wasn't too long. I liked how you showed the problems, the detailed view and the uncertainty which stays. And the process of decision-making. Portraying complex problems takes its time.
Thank you very much for sharing your knowledge.
@@OBS_Ford_Diesels_Inc I question my videos myself. What is too late my? How do I make them more watchable? What can I do to improve my editing style? Music? No music? So many thoughts.
@@sebastian_m I question my videos myself. What is too late my? How do I make them more watchable? What can I do to improve my editing style? Music? No music? So many thoughts.
It was quite long, lots to look at though! The key images narrated during editing could make it more concise if there is a lot of content. I do like listening to the real time walk-through if I’m not in a rush though.
No music for me in this style of explanation vid! That could have been unwatchable 😆
Thanks Blair!
Ever run into a situation were a client tried to sue over your assessment of a tree you left standing and it failed?
No
@@arboristBlairGlenn That was a point blank question and apologize for its bluntness but a friend told me that when I get my arborist certification I am announcing I am a professional and could be held liable for any assessment that might lead to property or person damage as a result of tree failure that I left standing.
@@geekay4703 it just has not happened to me. I suppose it could.
I think it would be tricky to prove in court. Any written assessment you give should be carefully worded and have disclaimers on it. Personally I don't give warranties on mother nature! Speak to whoever does your training/certification or other established professionals in your area. Get good public liability insurance. Look after your back, don't work for cheap customers with bad attitude. Do good work and word of mouth will do the rest. Good luck.
@@nothanks9050 Thanks.
So sad to see all those trees hurt so to say.
I’m trying hard to get the information out to the public so folks can understand what hurts the trees.
Hello
?
i feel like you have not pruned trees with out a book recommendation before.....rookie
A common problem with "tree trimmers" lol.
