That would depend on species, site, style and specifications and extent and season of pruning, etc. I don't think frank would say those results had universal applicability, and that axiom is just one aspect of biomechanics. Thanks for posting the link. If anyone here's gonna be in Hong Kong next month, he'll be repeating it here: IASHK: International Arboriculture Summit - Hong Kong

a third small stem has grown through the gap about a foot above the split?? got a camera?

Ha yes most relevant; thanks!

Maybe reduce to clear targets, and prevent damage/injury from branch failure, then install a tree-to-tree guy to direct after root failure if it occurs. ?

bump. Why this never got a reply I can't guess; advice is seldom lacking so badly. I'm revisiting the tree again this fall. Don't mammals defecate in your cr...um, the forks in urban british trees? i have not climbed enough over there to know. this tree's branches are over a newly rebuilt gentrified to the maximum house, and one frame house that is historical, at least to its owners, and a garage, fences, you name it.. these coons favor the same latrine so it gets quite nitrogenous I would imagine.

Hmmm that'll hasten the hollowing all right. If it fits species location why not? The fractured stem looks like the hand of the peaceful chief of a tribe one happens upon.

none at all; that comment was expanding into generalization. that's the internet for you... Yes totally; inevitables. i did nto see Japanese, tho i might have mistaken it for Javascript.

with the area fenced off, is target rating really high? Fascinating study though; I'd rather see it sprout and repruned rather than sliced and diced. if someone were curious i would suspect mere probing would reveal a bit.

Semantics but because of the low occupancy and the fact it is still standing it's a low risk." The thread was about terminology; how doth that differ from semantics? "That is a different beast though, a shear crack, where the fibres at the meeting of the compression side and the tension side have dislocated in shear. Still a good example though." mmmall the action seems to be on the tension side. but the main thing is, a lot of these terms get lost in translation, even when the lingo is the same. each tree is different, and vta tuning into "defects" can become a witch hunt if not balanced with tuning into response and adaptation.

Yes I've seen agrilus sp(?) borers do stuff like that, but never so big! a boxcutter type knife will cut out a wedge with less damage than a saw would make. the knotty stuff at the fork might be something else; could be cleaned i.e pluck out dead stuff to assess the damage.

Does that pine need action? If not, it's not a hazard, by definition of the term. This oak is hollow as a drum and needed action. Pruned 15% to lessen lean; that was 5 years ago; owner is fine with it. crack oak.doc

"Depth wise could be better for its future growth but that's not my problem." Does this mean they are buried way deep but you see no connection between deep planting and leaf condition? Suggest you reconsider that. Isn't the tree's problem your problem, or are you not the arborist/tree Dr.?

a quick skim shows a lack of detail re treatments that is disturbing; compost tea to foliage and woodchip to soil (composted we hope) do not sound practical without knowing more, and the "specialist phased retrenchment pruning" is tantalizingly obscure. It's another step on the path, but mind the potholes. will give it a thorough read soon, and hopefully see and hear more in hong kong in november, where nev was recruited to keynote on short notice, thank goodness!

Thanks chaps for keeping this one going, and the pruning treatments seem a good compromise between public and tree health. Gf fairly common here on our q phellos mainly, and noninvasive means of assessment seem to bear out the notion it is not a super-aggressive rotter. 15-20 cm is after all 15-20 cm. Across the pond here most arbs would not comprehend this, and i'm not sure i'm all the way there, but am grateful to see tree care practiced at this level. I'll be looking for that little hare, Gerritt, and thinking of the mycorrhizal associates. Carry on!

Agree with Tony here. No idea if you have a straight M grandiflora or a grafted hybrid--the suckering issue may be a good one to raise to lessen client pressure to whack hard. they are native here and i have seen them come back from hard pruning but managing the sprouts can be higher mtc than from a lighter pruning. frikn clients always wanting more off; like they do not want to see you ever again. weird ins. stipulation; is not passing the smell test, tho i am a ways off...

if that is cercis canadensis or other redbud sp., check the bark for old cankers, Botryosphaeria or D something

Mmm that is not the first genus desired is it? heres a pic of mulch gone wrong

Not to worry, you can go anywhere, by the sounds of it! This isn't a thread; it's a forum, it's a franchise. Arboricultural Passion pays!

David, the mulch appears to be rather coarse, and 6"+ deep. Am I seeing this right? The results are impressive. Cardboard is a great carbon source to jumpstart the ecological processes.

If aesthetic value is preferred, why not take some weight off the end and brace the crack with a bolt?

Langur is right; check for sticky droplets on branches. Also yes could be Plant Amnest speaks out against Shear Madness! there is more than one way to deal with it naturally, besides not being so tight on the clip. That is to make thinning cuts as well, every 2nd or 3rd shear at least. Yes more time and therefore money, but essential for healthy plants. Because shearing is non-selective heading, you will stimulate bushy regrowth. You create a twiggy outer shell on sheared plants. This layer of twigs shades out the interior, which then becomes leafless and full of dead leaves and dead wood. Meanwhile the outer shell becomes thicker and larger every year because, as it is sheared repeatedly, it must be cut a little farther out to retain its greenery. This dense, twiggy outer shell makes size reduction difficult because cutting back too far exposes that ugly dead zone inside the shrub. It is also physically difficult to cut through the thick twiggy mass. Although most plants will eventually green back up when they are pruned back into the dead zone, but as you now know, the needled evergreens, such as junipers, won't. Therefore, shearing is not a good way to control the size of a shrub. Selective pruning utilizing the thinning cut ensures that there will be a green twig or branch to cut back to and can therefore be employed to reduce a shrub's size while retaining its natural look.

Tony, my purpose isn't to make points like lines in the sand to debate but rather to explore areas of common agreement with folks who do similar work. Refining my understanding based on others' thought and experience is what I'm after. The "points" in the article such as they are can be found in the paragraphs. Started them with R's because many of the words do. The only specific response to the Retrenchment bit was from a bloke who wanted attribution for the "coinage" of the term to go to a friend who mentioned it at a pub. Okaaayyyyy... It's in American English so somewhat understandable i hope. You're right it could be more focused, but that is a work in progress, which is why I seek the example and experience of others.... Like an after shot of your beech reduction!

"prefer for language accuracy that decay be replaced with "dysfunction" mainly because it is a miss perception and continues the false impression that CODIT is about the compartmentalisation of decay, which it is not. An updated version would see this now called CODIT as the "compartmentalisation of DYSFUNCTION in trees" as oposed to the old model including the "demonic" D for decay. " Tony I'll agree that decay is misperceived as Demonic. As for what the D should stand for, Gilman cites Rayner and the rest in citing Dryness as the chief agent of Dysfunction, which is itself rather hard to define. We could also call the D Damage, or Dessication, but since Decay is the agent that causes wood not to be wood anymore, its Demonic status is not all that ridiculously exaggerated, in some contexts. Like you, I'm happy to work with and retain some heavily decayed trees. Recalling the parable about the 5 blind guys who tried to identify an elephant by pawing pachydermal parts: Q: How is a gullible young arborist assessing a hollow tree based on drilling its trunk like an old blind man assessing an elephant based on touching its trunk? A: One calls it a snake, the other calls it a removal, but they both call it wrong. "secondly, epicormic from bark as opposed to nodes is not strictly less stable, ..." Stronger sprouting arises at nodes, from dormant buds that lay waiting. These were originally accessory buds, formed when the terminal bud was set at the end of a one-year old twig. Dormant buds are carried out in the cambium as the branch expands, still connected to the core by pith trails, sometimes called bud traces. These pith trails are held fast by compacted xylem in the core of the tree, providing for the new sprout a thin but very real structural attachment to the tree's core. That's why growth from dormant buds is technically speaking endocormic (inside the core) rather than epicormic (outside the core). As a climbing arborist, I do not think you will doubt the strength of wood fibers! Anything else in there worth reviewing?

Don't want to derail here but windowing is not a bad goal--beats a hard reduction to gain vertical view clearance! one view of this from oz. https://docs.google.com/viewer?a=v&pid=gmail&attid=0.1&thid=1334840423039326&mt=application/vnd.openxmlformats-officedocument.wordprocessingml.document&url=https://mail.google.com/mail/u/0/?ui%3D2%26ik%3D0f8c96c720%26view%3Datt%26th%3D1334840423039326%26attid%3D0.1%26disp%3Dsafe%26realattid%3Df_gu93spk30%26zw&sig=AHIEtbScZka1kxXoXq9ij_INVPRzHfWacg o and thanks for the kind words re that post; the best "parts" were written by others though, i was just the messenger.
