Fungus Re-growth on new trees

[treeseer]

How and by what means can "invigorating" the roots after drying out the infected areas, which initially are the roots, ...

 

Well my goodness I am not talking about drying out the roots; that would be silly! I meant the infected areas of the trunk, of course. And I did not mention the soil replacement, a la the perlite that has been advocated over there.

 

"Salvage of what"

 

The majority of the tree, and its contributions, and the benefits to all stakeholders in the tree.

 

"with what guarantees"

 

The work could be guaranteed to be up to industry standards. Of course the results could not be guaranteed--when can they?

 

"and at what costs for the client?"

 

The cost/benefit calculation is the client's business, though the arborist can supply needed information. The R&R Removal-and-Replacement approach GUARANTEES the client will lose the value of the tree, and the cost of removal.

 

Would you guarantee that is always the best approach?

But we have to know when were wasting money and time treeseer

As the initial attacking strategy of parasitic Armillaria species is infiltrating the tree through the roots (hyphae, rhizomorphs) and then rising up the trunk blocking transport and killing the cambium,

- how do you think "drying out" the infected areas of the trunk can help the tree to compensate for the partial loss of its roots and stop further spreading of the infection to other parts of the trunk and

- how do you invigorate roots, that already are infected or are easily infiltrated by rhizomorphs actively searching for living substrates to colonize in the soil ?

"As the initial attacking strategy of parasitic Armillaria species is infiltrating the tree through the roots (hyphae, rhizomorphs) and then rising up the trunk blocking transport and killing the cambium,"

 

True, but this rising can be stopped by compartmentalization.

 

- how do you think "drying out" the infected areas of the trunk can help the tree to compensate for the partial loss of its roots and stop further spreading of the infection to other parts of the trunk.

 

Experience, and knowledge and observation of compartmentalization.

 

"how do you invigorate roots, that already are infected or are easily infiltrated by rhizomorphs actively searching for living substrates to colonize in the soil ?"

 

By "fixing" the soil, in hama's word--changing levels of air and moisture and organic matter and nutrients and , to improve root function, including resistance to and potential displacement of pathogens.

 

"But we have to know when were wasting money and time"

 

We do not have to "know", or guarantee, any outcome. But if we are working as arborists, we DO have to know the client invests money in our time because they value the trees. Should our first move be to decide to give up on the trees, without presenting other management options for the CLIENT to decide from?

 

Did the client here assign the arborist to be Chancellor of their Exchequer?

 

We have not seen these trees, so how can we at our computers decide that R&R is the only way to go?

1. this rising can be stopped by compartmentalization. Experience, and knowledge and observation of compartmentalization.

2. By "fixing" the soil, in hama's word--changing levels of air and moisture and organic matter and nutrients and , to improve root function, including resistance to and potential displacement of pathogens.

 

1. Any scientifically valid evidence and documentation of this happening in Prunus, a tree species associated with generalistic endomycorrhizal microfungi only capable of providing for a weak defensive (root) system and known for poor compartmentalization ?

2. "Fixing" the soil ? Resistance to pathogens ? I thought a complete exchange of several cubic metres of soil and removal of all rhizomorphs was necessary to facilitate replant of a tree, that is relocated from a nursery with damaged roots, so how do you prevent re-infection without removing all the soil around and underneath the "saved" tree and in between its roots ?

[Tom2020]

Well why you lot have been chatting ive been working,

 

Felled all the tree and grounded out the roots and removed all the waste from above the ground. Day two seen me,2 grounds men and the client all digging the soil and removing anything that looked like a fungus and anything else that we did not like the look of. In the end we planted 2 Tree with a 2meter round base of each tree Filled in with mulch and some new soil Staked tied looks the dogs now. Will try and get the pics of the client when i go and see them so you can all see what we did Thanks for the advice guys

1. Just images, the same as you can see, of infected Prunus standing.

 

Like Tom noted, this kind of chat goes nowhere without a common referent, in images and details and assessments, all lacking here.

 

Poor compartmentalizers are not non-compartmentalizers. Read the below.

2. Poor compartmentalizers are not non-compartmentalizers.

 

1. You refer to images, i.e. microphoto's of inside compartmentalization in (cambium and) sapwood of "infected Prunus standing" ?

2. Depending on the pathogen, in this case a parasitic Armillaria species, unless scientific valid evidence of the contrary presented, poor compartmentalizers, such as Prunus, are non-compartmentalizers.

Tom,

Adequate action - both for your client and for the credibility of yourself - taken after sound advice .

[treeseer]

Wall 4 images only; I'll have to "look into" hahaha this intercellular imaging that you now ask for. The bar for evidence of trees' potential you set mighty high, but the potential of fungi to inevitably and immediately destroy trees seems to be be accepted as a given by you two tag-teamers, regardless. Is this lack of objectivity scientific?

 

2. Depending on the pathogen, in this case a parasitic Armillaria species, unless scientific valid evidence of the contrary presented, poor compartmentalizers, such as Prunus, are non-compartmentalizers.

 

So "poor" = "non" in the mycophilic view? That's quite a leap! Again, you look for guarantees of the trees' potential, and consider decay as king of the forest.

 

Anyway, these trees are dead, as is this thread.
