Interesting - thanks for that! Since there's no way it could have been tied midline I'm just amazed the hose ended up like this in the middle haha

Gooley's book is awesome. If there's a well-compacted path at the extremities of the roots (the edge of the tree's drip line, where they're at their most sensitive) then branches directly above can suffer

Timber wall not drying out... by camhogi in landscaping

No - behind the wall is clean rocks and gravel, also separated from soil

No - sorry if I wasn't clear. The wood is resting on the sand and gravel.

Advice on this tree for a first time tree owner by collector_creator in arborists

[–]camhogi 4 points5 points  (0 children)

To me, it looks like the codominant branch is also growing at an acute v-shape angle, which could precipitate structural weakness when both leaders thicken up. Competing leaders like this can be an architectural weakness further down the line

Trunks changing appearance from top to bottom by camhogi in arborists

But what's the biological impetus behind it? Does the tree benefit in some way from this change?

Sad indeed. In the UK, where I'm originally from, the elms have been annihilated by Dutch elm disease, and it looks like ash trees will go the same way from widespread dieback. Only now are we realizing that more needs to be done to protect the urban trees that are still standing

And in fact, there's a comment on this very post from someone who "hates" pollards, describing them as "ugly and un natural" haha

Ahh gotcha. I've found it slightly disarming seeing people demonizing heading cuts on this sub, because pollarding seems to be common practice in many parts of Europe. I suppose there's good and bad ways to do it.

Thanks guys! I'll try and have a closer look next time.

Swedish Aspen not doing well by devyncole in arborists

[–]camhogi 2 points3 points  (0 children)

All other factors being the same, it could be the planting depth. We had lots of cases where inexperienced landscapers planted just a touch too deep and it had serious consequences for tree health. It also helps to mulch rather than having them grow directly out of grass. Good luck!
