If the rootball is moving after 5 years in the ground, roots are circling, not establishing support. Digging around it is key for re-settling, yes, but pulling apart some of those roots and aiming them outward might improve chances of stability long-term. Also it looks like the juniper is in need of pruning to lessen lean.

Scott, compacted soil layers also exist, naturally and through previous mechanical activity, well below the surface; see 'hardpan'. As with planting holes, gradients are mitigated by fracturing the soil beyond the hole, by moving the bar sideways. Less interfaces, more mixing, better results. Of course the closer to the trunk this is done, the more care is needed to avoid root damage. Not difficult really. The video showed this work very close to the trunk; not typical sorry. The evidence of benefit is seen when water drains more readily from a site.

Great picture and anecdote! The dog's teeth went way deeper than the strummer.

Vaseline not a bad idea; something to prevent moisture loss. In defense of your husband, when grass is grown up to the trunk, how is one to control it, with scissors? Before you mulch, you might want to pull back grass and dirt and find the flare, where the first root grows off the trunk. If you have to dig down to find the flare, that's a problem. Post an image of the flare, for more good news!

We avoid damage to any unforeseen roots, with the 'wrecking bar' by wiggling it first, and thrusting cautiously, at varying angles. (insert bawdy reference) Traditional tools for deep aeration include 2" augers. The bar is much less damaging! The span between each hole depends on root architecture and soil type, but yes 20-30 cm's is good, closer not needed. 5 for 100 = 5 Aqua-Cannons for $100 at our state fair, and at big box stores here. The tool is a joke; the process of penetrating subsoil is the message. But I like your thinking re $20/hole! Scott, what would you suggest, when drainage must be improved? I've seen roots growing downward into aeration holes so yes it works to deepen the rootzone.

Here's an infomercial for the wrecking bar and the Aqua-Cannon:

Tony, the 'site language' tells me of probable poor rooting conditions. This is not being litigated, and your bar of 100% certainty is too high, even for that realm, or anywhere outside a house of worship. If you have another thought on how that vascular discontinuity process might be slowed, I'm all ears. The pruning dose will have to be higher if that continues unabated, wouldn't you say?

Soil erosion alone does not signify poor rooting environment, but it's a strong indicator of that probability. Discontinuous trunks or fluting also does not always suggest poor rooting conditions, but seeing that trend develop is an action item, on the tension side, with the building under it. Compaction levels, nutrient levels and hydration potential would be checked by sampling with probes etc. before specs written. "poor rooting environment" is an assumption to start with; this all based on a 1-minute check during a 52-acre tour. Another factor is the ripe-wood being aerated and being colonised by a possibly invasive and capable delignifier (G. resinaceum for example). But it's not either-or! Root function boosts the tree's ability to defend against the pest, so soil works are not ignored while the fungus is assessed and admired.

Oh, those...Yes if no MEWP then pole tools are needed to reach the periphery. A challenge to reach the right cut, but there's no good reason to make a wrong cut.

If that tree's in Kew Village, I think I've seen it, and the plums indeed were good! That landscape tree looks like it might want a prop or two...
-
If not Quercus macrocarpa, then what?
-
Yes, vascular discontinuity is a poor condition. O, if you mean rooting conditions, yes the slope it is on has been artificially eroded (leaves raked) for a long time. As visible, that buttress is colonised on both sides. It is the tension root on the side away from the building. So if the gano's pincer movement renders this root dysfunctional, that would increase the risk of failure onto the building. Comprendez vous, mon frer?
-
The first pic shows vascular discontinuity on the buttress ~1m from the ground. Deep soil improvement for that root would be a big part of the plan.

"What would you constitute as a 'tickle' in terms of reduction spec on a 100' plane?"" This would be on a leader-by-leader basis, but I'd say <10%--5%?-- based on the apparent good attachments of the ~8 major leaders coming off the ~5m stem. The purpose includes being able to tell any defect-centric observer that yes, steps have been taken to manage load. "Do you think management of trees with decay issues like this one is directly influenced by tragedies such as the fatality of the pregnant women in Kissena park in Queens last August, which I guess is relatively local and still fresh in the conscience of the public and tree managers alike ?" As little as possible. The arb in charge is well aware of the many recent tragedies in NYC, but is able to react to tree risk in a specified and tree-value-centric way. Despite the media and the victims' solicitors roiling up public sentiment, conscience stirs vigilance, not arborphobia, in this garden. .

Pics do not show Any hollow If you wanted it gone then ok

Yes there are different observations Imagining a fungus munching inside o my Lets keep in mind that losing heartwood Can help the tree
-
BBG has a fine collection of vets. This one's pushing 100', and < that distance is the building. The conks are a feature of admiration; no fell-happy assessor has gained influence thank goodness. In anticipation of more such concern, it may be due a tickle.

Schhwarze's Fungal Strategies (2000) Chapter 4 begins with the compartmentalization model, and verifies that theory with microscopic assessment. Since most fungi which endanger trees’ stability work from the inside out, the ways that trees resist that outward spread are reviewed at some length. Xylem rays can be the trees’ Achilles Heels, the pathogens’ paths of least resistance. Similarly, xylem cracks produced by rapid drying after removal of a branch are “motorways” for infection, so the authors suggest that “the use of wound sealants could be quite successful against wound parasites. However there is still a great need for research here.” When large branches must be removed, experimenting with sealants seems preferable to opening the heartwood to decay. Aesculus is not so good with rot ime. How long do you all reckin that the wound will take to close? Is there anything that an arborist can do to speed this closure?
-
This colonisation has been part of the collection at the Brooklyn Bot Gdn for a long time. The progression has been very gradual, as has the tree's response.
-
Or better yet, assess the tree's strengths as well. "Defects" are less important. The woundwood on the edge of the canker looks vigorous, and indicates a favorable prognosis.
-
well yes indeedy. David, I also can't recall seeing failure at a target canker, except for such a canker from Cronartium fusiforme on Pinus taeda. Here's a Q robur in Brooklyn NY US
-
Applying sealant might slow drying, dysfunction, and potential decay. Reducing, not removing the opposite leader would be a very good idea. Any self-optimization done before is not reliable, under the new exposure to the elements. Perhaps 10-20% off the end; an arborist on site can assess and improve structure.

Is that fungus a serios wood decay species? Xylaria in the US is reputed to be somewhat sluggish
-
Historic by US standards, the building dates to 1734 US champ in size, I bid to fix the lightning system and remove the broken cables. I will climb and measure it whether paid or not Keen to inventory associates Owner not keento open wallet for nowt Horrible abuse by branch removal Collar cuts omg
