So what treatment would you suggest? My nose must be broken--can't whiff any Arm. I have seen those black bumps in other oaks, and found those lesions will tend to close if cleaned. Less idea what is going on inside... Totally agree that 2nd oak was a soil failure. I tend to blame failures on a lack of reduction pruning of overextended branches. My bias maybe.
-
Yes, an horrendously huge cut at that. Another mitigating kind of observation--the fork at the left of the pic has a similar color. If rain was recent, we might be stressing out about water here.
-
It can also be caused by sap leaking from underoccluded sites of severance. aka nothing special. Yes indeedy worth a return check. And perhaps scrub and rinse, to get a baseline for observations.

Here's a synopsis used as a handout, fwiw. Critiques welcome. RETRENCHING HOLLOW TREES FOR LIFE 131119.pdf

I just got a copy from them too; 11 pounds to ship; tolerable. Pretty good stuff on pruning, as far as it goes. Which is still a whooooole lot farther than any US books, sad to say. Great stuff overall; almost as good as the action shots with narration at arbtalk!

Other reasons for leaving it include shade from sun scald, and translocation of resources toward the 'collar' area. Stag heads are also good perches for raptors etc. That said, I generally cut back to healthy tissue. Too much potential for problems (Kretsch etc.), in oaks anyway.
-
Reduce what sticks out until no part left is highly prone to breakage. It's up to us to interpret the tree's language for the client.

Just put up this old vid on fixing misplanted trees fwiw. Are these donuts common in your area? does anyone else work with them?
-
Perhaps that side is not so thrifty because the food once made from that big limb is no more. Add increased heat etc. from exposure, plus root death in response to branch loss, , plus the need to grow scar tissue, and that's bound to be bad for the tree. Trees are often hurt by 'collar cuts'. The leaking seems of little consequence; would a scrub and a rinse be good?

V.T.A symptoms "the chatty trees"

If he recommends removal without considering soil work, get a second opinion! I'll be in Tampa next month... -

Yes it looks like a laurel oak. The bugs are only scavenging wood that is already dead. Most of your trees' problems are underground. The rootzone looks barren and compacted. The black streaks are an infection from the soil. No local arborists? You do know this is a UK forum, right? -
Yes quite vigorously as well. These pics from austin tx, Ulmus crassifolia was half-felled when i pulled up to the hotel. No reason to it at all; sapwood very healthy. i hope the aerial rooting shows up.
-
Why cut at all? If stability is the objective, consider support.

I cuticularis not mentioned in my US references. Name comes from that distinct white stripe along the edge or 'cuticle'? Steven, with all Inonotus ime, degree of compartmentalisation appears to be very much related to host and site conditions.

Sites 30 miles south of me are being explored, and legislation pushed through to enable it. How badly do we need more gas? No shortage at all. It can kill trees, which might make it arb-talk. or not.

Diseases of Trees and Shrubs (sold by TCIA) comes from the same Cornell campus as Dr. Hudler. On pages 354-366, Dr. Sinclair describes many treatments for Phytphthora: 1. Fracturing subsoil to allow deep drainage, as without free water the disease cannot spread. 2. Amending soil to improve structure 3. Inoculating with microbes to outcompete or directly attack the pathogen. 4. Applying calcium fertilizers or soil amendment with gypsum. “…calcium calcium compounds interfere with sporangium formation and zoospore function and thus suppress infection." 5. Drenching with “Phytophthora-suppresive fungicides to limit damage." 6. Drenching with “…resistance-inducing chemicals such as potassium phosphate.” 7. Surgery to remove inoculum. “(Phytophthora sp.) derives nourishment from recently killed as well as living tissues, and it reproduces in the dead tissues." 8. Applying heat to kill pathogens and promote closure. 9. Injecting minerals or fungicides.

Fair enough then; these are minor issues, within broad agreement on arboriculture.
-
So a bit of haloing then... Only related somewhat, but just ran across this paper again. The author missed the form of rejuvenation from retrenchment pruning, but still a useful view: http://arnoldia.arboretum.harvard.edu/pdf/articles/1999-59-4-aging-and-rejuvenation-in-trees.pdf

What a graceful form; would love to see in winter! (subtle as a brick, as well as thick). Any pruning works of late?
-
That would be interesting! I'm still not comfy with aberration, abnormality, deformation etc. used as descriptors on an intuitive basis. But that's just me.
-
Ah but doing it in private would be a waste of your talents. If 'abroad' ever becomes the US look me up and I'll show you us yanks aren't as crazy as some brits make us out to be. We're crazier!
-
It appears then that review made you a Published Author. I'll gladly paypal the expense if you wish. Thanks kindly for your efforts good sir, on both the posting and especially for writing and submitting the review. We need more stepping up and doing such! I would also value a signed copy of the review as well. Might be worth something someday when you are famous.

Whilst searching the local U library for the Lonsdale (ed) book on vet tree mgt, all that came up was this: Antony Croft, Arboricultural Journal, (20130920): 1-2 was this a review, letter to the editor, or what? Possible to see? It also said "STACKS -- SD1 .A69 (regular print) -Includes former title, Arboricultural Association journal.-;v.2 (1971/1976)-v.29 (2005/2006)" All US sources are telling me the book's out of print--anyone know how to get a copy across the pond?

It's just you. Jules, how can one tell the difference between reaction wood and 'growth abnormality'? How can this be demonstrated? btw, 'Dundee' in the attached is Cassian; I put him in there to honor his cataloguing of this phenomenon. Also, Dr. Frank Telewski was kind enough to review it. Boy, did I get schooled! In his words, all wood is reaction wood. And he should know! A unified hypothesis of mechanoperception in plants Detective Dendro and the Wondrous Washboard (2).doc
