Can you add a top layer of fresh soil? I'm just thinking it could put some fresh life in the pot
Your thinking is 1A!

Just, to
have "fresh" that is better than the "old"
My vermicompost isn't so bad, actually it's pretty balanced and completely aerobic, just still too bacterial.
Still better than anything I can buy at the mo. New batches of bagged stuff haven't hit the town yet (and even then, very few will even be aerobic, never mind the microbial diversity I'm looking for), and the old stuff from last year...stored all wrong, even what wasn't so originally is full of pathogens now. I know. I'm the one leaving small mouse holes in diverse bags all over town from taking small samples from them ha
I
did ask in the beginning, explaining what I'd do and offering to share the info

, they had no idea what I was talking of and didn't care.
And I'd be out of my mind to put money on the table for stuff I don't know the quality of,
knowing they don't care.
I'm going to be checking on the VC today or tomorrow and will probably make an aerated compost tea of it and water that into the soils. I still have trouble imagining how topdressings actually seep down into lower layers, though obviously that is the way it works in nature

Plus, the microbes in AACT are highly active and ready to get helping, already producing glues to help aggregate the soil more, like a Ninja team, whilst the ones in the compost itself are in a more leisurely mode, like pioneers loading their wagons to move West.
Cheers!
