Mycorrhizae is making a fair amount of noise in the maple world
"outre pond," I'm wondering if anyone on the rational side is using
it. This is symbiotic fungus, essentially, although there are many
different forms available.

I'm considering trying with this spring's plantings. Any experts recommend
a brand available by internet?

Thanks!

Yes, they are used for a few plants which don't grow well without
mycorrhiza, and where the fungus is relatively tractable. Blackwood
(a type of eucalypt) is one, if I recall. You can also regard
truffles as mycorrhiza, and some of them are cultivated.

You have been reading too much transpondian New Age drivel, haven't
you? :-)

Some fungi associate with many plants, and some plants associate with
many fungi (birch is the classic), but only a few combinations will
work. Some plants don't form mycorrhizal associations at all (e.g.
yew), and some are almost impossible to induce artificially (e.g.
many terrestrial orchids).

The first question is to ask what you want it for, the second is
whether those plants form mycorrhizal associations, the third is
whether it has been induced naturally, and the fourth is whether
that species is available. Only fifthly worry about the brand!

Sorry, but ....

Well, possibly, possibly.

yew), and some are almost impossible to induce artificially (e.g.

I could be more specific. What I want it for is to increase verticillium
resistance, via stress reduction, in various Acer taxa. These plants
are well known to form such symbiotic relationships, hence the
discussion in the maple community (including the Maple Society,
which I can attest is reasonably serious about the subject).

Maple growers often "juice" rootstock with mycorrhizae. It appears
that endomycorrhizae is preferred for the genus but some references
do appear to cite ecto.

I'm not quite sure what you mean by "induced naturally," the fungus
is almost certainly present in the soil here in places, but I may have
introduced it via plantings.

By "that species" do you mean fungus or plant? Americans in the
maple trade have mentioned www.mycoapply.com as their source,
there is anecdotal evidence there that these work well with A. palmatum
anyway. My collection is much wider ranging, so I'm thinking about
using the stuff across a wide variety of the genus. But some of
the plants I expect to receive this spring (A. diabolicum, A. distylum)
are really extremely rare, I am hesitant to try anything new with them.
(In fact I don't expect diabolicum in particular to have a verticillium
problem, but various other issues like pseudomonas are always a
problem in our wet climate, and I do find that general robustness
helps a lot with any sorts of cambium sickness.)

And so, I am asking about the brand, and if anyone in our climate
uses the stuff!

This film is in aid of pushing the companies products, but does have
some interesting background on mycorrhizae.

(I'm in no way affiliated with these people, nor can I vouch for the efficacy of their
products. As I said, just interested if anyone over here is using the stuff.)

Ah. Not, THAT makes a LOT more sense. But you should always make it
clear that it is Acer you are talking about.

Oops. I meant "induced artificially".

Fine. But, if I were to refer you to something that I was using for
blackwood, oak, beech, or growing truffles, it wouldn't help you at all.
I am not, but I thought about it and looked into it a little.


Aside (not to you): God. British botanical loons, again. So ignorant
that they pluralise the obviously Greek-derived word "mycorrhiza" to
"mycorrhizae". And the OED confirms that it is precisely a British
botanical delusion.

I still remember a speeling test at my first prep. school that foxed
everyone with "hippopotami" (he pronounced it "-MY". No, that is not
the correct plural, as several of us (aged 7) knew. Of course, it was
a common local wild animal, and not an exotic.

Seems that mycorrhizae is in common use. Probably far more so than
mycorrhizas. (Would you prefer "mycorrhizata"?)

I haven't trusted the OED since "monied" was disallowed on Countdown...

I think that you will find that "mycorrhiza" was both singular and
plural until some, er, considerably sub-genius decided to Latinize it.
The earliest plural of that form I can see is "pileorrhize".

Why the hell that usage couldn't have continued is beyond me. But
the whole way that the British botanical loons attempt to abuse the
English language is ridiculous.

After all, the very concept of singularity and plurality is completely
alien to mycorrhiza - yes, there is the concept of a single species
versus multiple species, but you need to say "species of mycorrhiza"
to disambiguate it anyway. And then the number is associated with
the word "species" :-)

About 2 to 1 on the evidence of Google. (198,000 vs 92,300.)

E - you're gonna need a combination of endo and ecto mycorrhizae for maple. if you go to this website reforest.com/forestry_habitat_products.php (it's not the best website, i had some difficulty navigating around on it) they have just the thing. i think they're canadian or something, so they know what they're doing. they also ship internationally (got me my stuff here in germany)
good luck
