Emergency!! Mold all in medium of expensive new plant!

First, calm down. Are you sure it is mold? What tyoe of plant, what type media is it in? Can you put up a picture? You can leave most plants out of media for a while, wrap the roots in a damp paper towel.

It's a Phrag. China Dragon 3N and it's FULL of mold - all in the medium. He said he had just repotted it and that seemed clear. There weren't really any rotted roots and no medium stuck to the roots. I think that it probably got very watered and then didn't get air - I know because that always happens to me.
I started soaking medium last night and wrapped all 3 plants in damp paper towels. I just need to know now if I have to soak or treat those roots / plant and how?

Sometimes I got mold on the media when I repot the plant. It usually happens if the old media was bark. If the plant seeme strong, and has a lot of roots, I just leave the mold alone. But if the mold is too dense, I poured peroxide into the media. The mold will go away once the plant has more new roots and start growing. I hope this will help.

Thank you! So I already dumped the media and have my own soaking. If I just repot it, do you think the plant will be OK then? I don't need to worry about anything else?
I freaked out cause this is my most expensive plant to date (wish I could say forever LOL). It's hiding a spike he said. And mold has done horrid things to my other plants, may they RIP

I think the plant will be fine. Although you might still see some mold in your own mix. I think there is debris of the old bark attaching to the roots that harvest the mold. You usually see them the day after you water the plant. I read that mold on the media is not harmful to the plant, and quite a few of my plants (with mold initially) were fine. Do you have a fan in your grow area? It might help with preventing rot.

I do have a ceiling fan so I will pot it in the new mix and put the fan on it high...

What you are seeing is probably not "mold" but a form f algae. It is very similar to 'pond scum' Plants that have come from a very high humidity or frequent watering situation often have this. Don't worry, it won't hurt the plants. If you have unpotted them, just repot in clean pots with new media. I wouldn't do anything else unless to have some Dysan or similar algaecide on hand. I have several plants growing happily with algae in their pots.

I just bought a Cambria yesterday (not expensive or anything), it seemed fine, but this morning it had grey mold growing on the top medium. I removed the worst infected pieces of bark (i think it is mixed with spahg aswell), and thought that I would just let the medium in the pot dry out killing the mold in the process.. Is this at all possible? Or will it have set spores?

It was very overwatered (bought it at a supermarket) so I think that might be the reason why..

Do I need to repot??
