How does one 'keep clear' of a big tree in their yard? Move to the Gobi Desert? A precautionary approach sounds like a defensive approach, which is not always defendable. I hispidus is sluggish in oak and gives plenty of warning, ime. Yes in ash it's worth a closer, balanced look at what is, with less of the 'what if'. Why would a TO refuse to allow reduction? Did they apply to take 90% off?

The question is, what are those orange-red bumps? they resemble nectria cinnabarina but darker, and they sure are packed together tightly. in the US it is a Very weak pathogen/saprophyte, so it's likely a secondary issue. if those are graft unions then the grafts failed, and i agree that is not an insurmountable barrier.

Doubting phosphite would control phytophthora in the ground. Rated for 'immune system boost' on living trees, sometimes quite effective for that.. Best to work on drainage imo. too bad (i think) alliette banned over there.

"Painting white here in the Uk is a rarely thought/talked about application" Why not? Very common in other areas, like China, Thailand... And if done, it need not be talked about, as the paint would be scarcely seen from the ground. Wrapping exposed areas is another option. i've used silver duct tape, a few times That pic of yours is so severe a 'reduction, stems need protection for over 12 months don't they? so the timing is less important? or do they resprout so vigorously it's soon shaded? "I suppose one tree aspect we seldom see (even whilst cutting) is the one from directly above which is where mid summer sun can do its fiercest work. It would be nice to have that view on every tree! .

Perhaps we are talking about different doses of reduction. >20% rare for me; i do more like this guy Tree Morphogenesis E-Books so i did not have sunscald risk in mind.. in that case, wait or paint it white. pruning collar dujesieffken.pdf

Yes, the 'Avoid pruning when leaves are forming or falling' advice is something of a myth; hard to admit that after repeating the phrase a few thousand times, but borne out by new research in hamburg and florida. For beech, spring may be the best time in terms of getting new growth.

to be expected; nothing too bad in those pics. root-girdling roots are seldom an issue. the tree broke the stem-girdling root in that pic; nice work, tree!

Cheap means of aerating and inoculating soil include swinging a pick or iron pry bar into the soil and bending it in 4 directions, followed by a blasting with the garden hose.

yes tha twas a poor phrase. It's surrounded by other larger healthier trees of the same species, so its shade etc value is not that significant. as it has been pruned back, its neighbors are spreading to occupy that airspace. see image. And yes, "root rape" is technical jargon in these parts.

Yes Johnson and Hauer did good documentration there, but being university guys they left it to others to describe practical solutions. Hauer and others were later questioning the practice of ungirdling buttress roots. The consensus seems to be that if stem tissue is not girdled then retention should be considered. On your beech "The 'air'cavation uncovered a number of partialy grafted and ungrafted girdles & evidence that the decay was mostly concerned with the older lower root system. The girdles will undoubtedly be having an effect on the vascular flow, root vitality & the trees ongoing battle to regenerate new roots to keep the balance of new (over) & old (under) tree, optimal." it's a tough call. The tendency would be to favor those pathways that seem to contribute the most to codit. Where guesswork seems to be more in play than decisions based on evidence, then doing nothing is one policy. But ungirdling everything that is not grafted does save the tree energy, and striving for that old-new balance seems quite reasonable. It depends...

Gorgeous documentation thanks What we need are connective glasses with fungicentric and vta lenses Arbotrifocals!

"well that woundwood is just the last uninterrupted vascular pathway, how do we know it's the last; have not seen 360 degrees (yet?) " it may look like wound wood but its just growing, yes it is growing in response to the wound made by fungal activity. aka woundwood. "unlike the dead (necroses) beside it which also is a bark "sink" indicating intense degradation behind and cavitation in progress to become an open cavity IF the tree survives potential failure and can maintain enough function and more importantly fluid within those last again, all of the other columns may be intact and functional, so 'last' seeems a tad melodramatic. "active uninterrupted vascular pathways. the evidence for the depleted resources are the bark sink, its there in the body language, VTA Yes thanks i agree the sunken area indicates *some* resources are depleted, but could this not be localised, and the entire tree system still be largely intact? and that area appears sunken relative to the raised area of woundwood/adaptive/reactive growth, so how sunken is it really? how intense is this degradation? unti l the rest of the tree is assessed, the panic hypothesis as i understand it remains unproven.

good question; mine was just a quick pro bono look so far, requested after the school got an opinion from an arb who did trimming there. given the rapid decline and duplicaiton of canopy benefits and apparent root rape, there seem to be few other worthy options.

Yes certainly looks like it; some older than others.

1. Shade 2. Beauty 3. Air purification 4. Water uptake 5. Wildlife value 6. Etc... O and the right to trim it to the extent it will not damage the rights of the neighbor to their enjoyment of the asset in common.

Nice looking tree--how was it before?

Can't see anything from here. PTSD?

Quercus phellos at a schoolyard, with a lot growing on! Well they look like cowpies to me.

"Would perhaps hide an eyesore, but not entirely sure it would do much else? Slow dessication, and all the other D's that follow. Enable interior parenchyma cells to generate new cambium--faster sealing. "Might cut back the left hand side of the bark to where its not loose to enable & promote callous regrowth Not much loose to trim by the looks of it but ok. Far more important to Find the Flare!

Also in that shot the incompetence of the istaller is on display; buried flare. re band-aid, tacking the bark back on might arguably do some good. I cannot think of a reasonably arguable pupose in removing that street tree. Assessors tend to judge a book by its cover. Branch scars are irrelevant to structure; roots could be fixed , or ignored, either way the tree is viable, maybe for a good long time. Unless I am missing something?

so, in the previous post looks like a mowing machine got a bit too close. Is glyphosate really all that bad? and in this one the maple had some pruning done with a truck it seems, and no one straightened the roots or took that wooden stake out why the removal? crown looks good dunnit?

yes just strongly opinionated folk taking a break to sing Kumbaya I have the highest respect for Mr. Croft's expertise. Even when he is wrong!

you think bark plates popping requires thinning of the wall?" ? what wall? I'm just suggesting they could pop off due to tree movement or fungal activity or unknown factors. "no fungi involved till after these entirely mechanically induced symptom, the barn door will have a shallow cavitation involving sapwood an inch or two behind those occlusion rolls, thats about all you can say from the decay angle." Yes, the wood decay angle, but I'm suspecting a bark-specific fungus. not betting on it, but if torsion then where are cracks? some kind of bending at play perhaps yes. "Yes, fungi and decay are my fave topic, and Im doing fairly well on it, as youll no doubt find out in due course." Hmm no doubt? careful there; it's a lot easier starting those projects than finishing them, I'll warrant--but I wish you godspeed! "I didnt place a smiley on my last post but I will add one now just in good spirit, at your comments:biggrin: Backatcha brudda

Remarkable; each rib looks like it was fashioned and fastened with deliberation. O and I stand corrected re coinage after rereading Cassian's piece. He's Chamomile Dundee in the attached, but he has also been Cal Modulin, a deeper name biologically speaking. while on the reaction wood derail, not sure i put this up before or not dendro washboard.pdf
