If i forget to use mycorrhizal when potting up?

[GMO]

Hi all,

As the title kinda says;

Whats going to be my most effective way off applying a mycorrhizal inoculation if i forgot to dust the potting up site and didnt make direct contact with the roots initially?

I am using DynoMyco but have heard topdress isnt advised?

I dont even use any of those no more. All snake oil in my opinion.

I did a side by side experiment , same cuts same everything but the mychos , not a modicum of a difference.
