This happened 2 grows ago, started to see this in the dirt then the leaves started shriviling up and turning yellow then they were all dead.

What do I do now? Transplant them all to new dirt? Any idea of the cause of this?

Worst thing would be to stir the dirt up to get rid of it right?

ewwwwww.
I'd vacuum that off then replace it with new top soil right away.
Aaaand in the long term, maybe more perlite and water less often?

Alright thank you very much for the response, also I meant pythium the root rot disease

I don't know, but that looks like a solid estimate to me

Dirt has been shoveled off the top, took the whole top 2 inches, not seeing any more mildew looking white powder in the dirt anymore, should I swap dirt and get new pots?

thats not pythium, its just mold, you water too often, and the surface of your pot stays too wet. let your pots dry out more between waterings . you can turn that over in your soil and it'll die, it needs light like algae to grow, but i'd just get rid of the top couple of inches and replace it.

H202 in a spray bottle probably wouldn't hurt.


I myself wouldn't bother replacing to much dirt as they probably won't get much if any root growth in it.Possibly just resulting in the same thing again.
