oak problem

[Tony Croft aka hamadryad]

in english please ,your not on the krypton factor !!!!!!!!!!!!

 

was that for me? cant see how i could elaborate any more!

Not really a problem just dysfunctional tissue. Do you not see this on nearly every oak of a certain age ?

I have no profile pitchures of the tree in question!! There is evidence that the tree has been reduced before but only to the lower lever arms. The canopy is however quite sparse!!!

 

here is all the pitchures i have

i have never come across this on any Quercus sp before!!

I am pretty certain what you have here is a common situation

 

A tree gets overloaded the bark thins on the tension sides, (upper) then a surgeon comes along and reduces it hard to relieve the tension, the thin bark gets exposed to an abnormal amount of heat and light and scalds, then dies off.

 

you often see it with a lightning strike scar because the strike often does the same job as the surgeon, loss of a top or heavy side branch opens up the canopy and sun scald.

 

tree seems to be occluding the wounds o.k though, keep it reduced and a watchfull eye on it and it will be fine, further , a lot further down the line heart decay might be an issue but managing a lower profile should see it well into the future.

 

Oaks a tough as boots kinda tree.

 

 

I will add-

 

try to retain as much epicormic growth oround the occluding ribs, this helps feed the callous

Does almost look like multiple lightning strikes dosnt it..i know it isnt thou.Did you use a hammer and do a sound test on the bark and decay?Think it needs quantifying as to the decay extent thou, whats the target area lke?Looks like a road below.I would be worried about internal cracks forming in the future with all that tension in the limbs.

 

Intresting.

we just poked around a bit!! Targets are dwellings and a road. on some of the defective branches there is some longitudinal cracks that have developed.

I was doing the aerial inspection with Charlie, and many symptoms point towards Stereum sp. Does anyone have experience of live oaks with this decay?
