Advice on dying tree

[Taupotreeman]

As far as I know only really MAF and some of the bigger DoC centres. When I asked about the possibilty of HF in the region (naff all on the net about it) a couple of people I spoke to didn't even know what it was. Still waiting for another centre to ring me back. If I have no luck I'll try MAF (ministry of agriculture and fisheries) and see what they say. Comes to something when arbtalk knows more than the national conservation outfit. And that certainly isn't trying to be derogatory to the arbtalk community, far from it.

Honey fungi are ubiquitous around the world as far as I know, and in the begining you said they had lost other shrubs, that a limb died and then more and then the whole tree is indicative of root colonisation.

 

but what seals the deal for me is the sprinkler, over watering leading to sodden conditions is one of the chief primers for honey in gardens.

 

Hama, sorry to sound so thick but is mellia the only species of Armillaria that will kill trees and is Honey Fungus a broad term for all Armillaria species? The reason I ask is that if it is mellea then MAF bio security are going to be extremely interested.

I've been trying to figure it out. I've seen it before but I just can't put my finger on it. It's probably common as muck but I just can't name it. If you recognize it put me out of my misery.

I hate to admit it but my tree ID has been pretty lax lately. Too long in Auckland trimming Willows, Wattles and Bamboo out of power lines me thinks.

I'll take your word on it Hama, who am I to question? I'll convey the good news to the land owner. Might have a bit of dig in the soil once they decide it has to go. Looks like I'll have to keep an eye on the rest of the trees in the area too. So far only the Rhodies have been affected and this one tree but if it's Honey then I presume the other trees could possibly start showing syptoms at any time?

 

Honey can be saprobic, i believe there is one that is entirely so, others parasitic at some stage or other. If the conditions favour honey it will do some damage in the vicinity and uses dead material as a means of exploring new grounds.

 

It has to be born in mind however that honey is not an evil curse, it is a symptom of poor managment, a weak stock, maybe improperly chosen species in a plot, and overwatering is a big helper to the honey.

 

There are 17 species that I am aware of, maybe more that i am unaware of? we have 7 in the u.k i believe?

First thing I noticed was the new hard landscaping? around the site. Root damage and compaction allows pathogen entry. Only a thought.
