Mold or fungus growing in gritty mix?!

Posted by AKluthe none (My Page) on

I've got this fuzzy gunk with small little spheres(all purchased from the same source) growing in/clogging the gritty mix.

Anyone experience this? Is there any hope beyond nuking the site from orbit?

That's weird. Where do you live? Humidity? You wonder if there was some nasties already living on the introduced bark fines?

RE: Mold or fungus growing in gritty mix?!

Well, for what it's worth, my bark fines came from someone else who isn't having this issue, and I have other plants from the same batch of gritty mix that are doing fine. They've been in it since December, maybe? And until the last month or so, they've been inside.

I had a crested graptoveria I posted about here that had stem rot. After cutting it down to save it, I found this junk growing down in the roots. I've since cut down two other plants after finding this stuff (though they were leggy and I planned to behead them anyway.) I now found it in this haworthia and a couple others. The only plants I've found it in came from the same place.

I wonder if a hydrogen peroxide and water mix would be useful in this case? I haven't done it, myself, but perhaps other could advise on the particulars.


RE: Mold or fungus growing in gritty mix?!

Is peroxide the preferred method of fungal removal? Is it preferable to something like physan?

Can't tell for sure from the pic....but maybe root mealy bugs? Just a thought!
