Mycorrhizae storage and propagation?
« on: April 15, 2015, 01:43 PM »
With this springs repots, I have been able to gather chunks of substrate that are full of the beneficial fungus. I've added it back to the trees being repotted as well as a few that I have collected this year and still have a bunch left over. I would like to save this material to add to trees that will be collected in the coming weeks.
So, the question is...how to store it and would it be possible to grow more by adding bark chips or something? Anyone with thoughts or experience attempting this, your counsel would be greatly appreciated. Thanks in advance.

Every reputable person I've asked about this or seen responding to similar questions indicates that the mycorrhiza will form on its on where conditions warrant it.  I think growing/propagating it outside of a host plant environment will be futile, symbiosis being what it is.

Bwaynef, thanks for taking the time to reply. Howere, perhaps I should have posted this in "Advanced Collecting" because I did not make it clear that ideal primarily collected plants that I find in the high country. If it's futile, that's one thing, but if it's achievable, I do see a ton of value in being able to harvest active, established mycorrhizae.

Jerry, thank you as well. I currently use the powdered stuff that can be purchased.

I currently dust all material that I collect with the powdered form as well as when I transplant collected material to its first pot. I guess I put it on all conifers whenever I end up in the roots. When collecting or removing mountain soil, you inevitably lose some of the beneficial fungi that was/is helping the plant survive. Since survival is of paramount importance, I see no reason not to give it some help re-establishing the relationship.

The added advantage of what I have on hand is that it is established, viable and flourishing. Moreover, I always have concerns about washing away the powder/dust with the initial watering. These clumps of fungi do not seem like they will " wash out".

I thought I saw on a Sandev YouTube video that he alluded to growing it on bark chips to add as a substrate amendment and even queried him, but never got a response.

Anyway, unless otherwise advised, I'm thinking about trying a couple different medium for propagation. I suppose I will try to replicate the grow box environment. Cool and dark. Or, maybe the way to go is to have a host plant whose purpose is just to farm the mycorrhizae.

Still love to hear some more thoughts. Thanks

Patrik

Fungus are micro-organisms. On an irregular surface (and even a smooth one) , you can wash with water as much as you want, they are still there and they will grow when they'll get sugars  from the tree so I very much agree with what  Bwaynef has stated : " the mycorrhiza will form on its on where conditions warrant it."

I'd just inoculate your other trees when repotting one like you've been doing.  Or, you could seed an area under the species desired in the landscape and mulch over it.  Most mycorrhiza are species specific to my recollection. 

I inoculate a week or two after I repot storing media full of mycorrhiza in a bag in the shade for the interim. 

I've never tried to "farm" it, so please post your findings.

I use a soluble spore powder from Fungi Perfecti - it has the longest list of species of the USA sources of spores for mycorrhizae that I have encountered. But if you want to add already active mycorrhiza, I understand your motive. I think the wood chip grow box might work, give it a try. Also keeping one or two trees to serve specifically as mycorrhizae donors is also sound. Keep up posted on your results.
