Starting this thread to see if any fellow Mirai members have tried—or are currently using—Dynomyco for their trees. If so, I’d love to hear about your experience!
This will be my first season using Dynomyco to inoculate Coastal Redwood and Dawn Redwood. I’ll be sure to share results as they come in.
Since the propagules are encapsulated in particulate form rather than a fine powder (like Mikro-Myco), and because it contains two strains of AMF (Arbuscular Mycorrhizal Fungi), it seems well-suited for mixing into aggregate soils during repots where we suspect fungal inoculation to be beneficial.
That said, I don’t believe this would be ideal for Pines, Larches, or other species that tend to associate with ectomycorrhizal fungi. Happy to be corrected, of course.
In theory, it should work well for species that are compatible with AMF (endomycorrhizal) fungi.
Looks like Dynamyco does not have many strains. I use Great White Mycorrhizal Fungi Beneficial Bacteria for Plant Growth, Root Stimulator, Concentrated 3-in-1 Formula by Plant Success
however I plan to try: Mycorrhizal Landscape Inoculant – BioOrganics LLC which was recommended by the organic farming supplier where I trade:
“This product contains the same nine Endo types of mycorrhizal fungi, plus an additional eight top types of Ecto mycorrhizal fungi spores - Lacarria laccata, Pisolithus tinctorius, Rhizopogon amylpogon, R. fulvigleba, R. rubescens, R. villosuli, and Scleroderma cepa, S. citrinum. The guaranteed Endo spore count is a minimum 50 spores/cc, and the Ecto spore count is a minimum 50,000 spores/cc. - more than 30,000,000 per lb. Landscapers can use this one mycorrhizal product on any type of plant - Endo or Ecto dependent.” as I have both Endo and Ecto dependent trees I use one product that works for everything.
Yeah, that makes sense—Dynomyco is an endo-only inoculant with just two strains in the mix.
From what I’ve seen, people tend to approach this in a couple of ways: some go broad, using multi-species blends to cover a range of potential symbiotic relationships, while others use more focused mixes with strains known to pair well with the intended hosts.
I’ve used Mikro-Myco in the past, which seems similar in intent to the BioOrganics product you’re planning to try. Personally, I like the particulate format—it just feels easier to work with compared to powder or spray.
I’m (perhaps optimistically) hoping it helps maintain contact between the inoculant and newly forming roots rather than potentially washing away too soon after application.
Majority of my trees are Endo hosts and honestly I didn’t see any type of increased vigor, growth, drought or otherwise increased resistance etc. after using the Mikro-Myco product.
When I mix my nursery soil (1:1 partially composted pine bark: Stalite + nutrients), about 1 cuyd at a time I dissolve the Great White inoculant in water in a watering can and sprinkle it over the batch before mixing. The mix is stored in a bulk bag in the rain. I use the nursery mix for perennials, seedlings and primary development. Up potted pine seedlings in pond baskets develop a thick white coat of mycorrhizal fungi. Likely the pines get the fungi from the composted pine bark. When I worked in a nursery 60+ years ago, compost was an important ingredient in all the soil mixes.
