[Chipchopper]

Has any independent trials/ studies been done on the above product to compare its viability with similar products

TIA

quite a few research links here. I believe that the RHA have done trials and now endorse its use but that is not actual research. https://www.frontiersin.org/articles/10.3389/fmicb.2015.01559/full

We have roses around the front of our house and the wisdom is that the ground develops "Rose sickness" making it difficult to replace roses which are past their best. We tried replacing a few and the replacements just didn't take. We then tried using Mycorrhizal Rooting Powder when replacing 4 roses and they all survived. Flushed with success we replaced another 2 a couple of years later and they also survived. Not a scientific study but enough to prove to us that it was worth trying again if the need arises.

especially useless actually but hell this is AB - very prone to recall and observer bias

woofies article easi;y the best of three posts is a review article (where did you find it) - and in posh language says
you really have to explant the soil

mycorhizzal powder cannot be purified so the trials cant really be controlled but they are looking at reponse rates of 90% in the lab.
wow !

very good review article - I feel like I know a lot about mycorhiza now
