White 'stuff' in compost/soil ?

My container potted plant ( species unknown also! ) has white stuff just underneath the surface. Is it some kind of disease?

    It's fungus, Suzi: probably nothing to worry about, other than "your pot is damp enough to grow mushrooms!".

    Most people hate finding fungus in pots (and in bags of bark chippings!) because we all live in fear of honey fungus etc, and because it is quite unsightly, but it's not really that bad a thing.

    For your pot, I would suggest raking out the loose fungus material, ie the top layer, and replacing with fresh compost: in effect, top-dressing. When you have time, I'd suggest repotting the plant into fresh compost, as it's possible that the soil has become quite compacted with age.

    Next winter, I'd suggest standing the pot up on legs for better drainage.

    Oh, and it looks like a Geum?

    Ok. I did repot it last Year as it was spreading like crazy. I put a post on here for identification & yes you said it was a Geum I think. There were a few suggestions but it hadn't flowered at all unfortunately. It has just come back to life after dying back. I will give it some new compost- thanks so much again!

    Yes. The vast majority of soil fungi just break down dead material, and do no harm at all, and quite a few produce white lacy stuff. Personally, I would just ignore it, except to ensure that the pot doesn't get too wet.

    Ok! Thank you so much for that Nick.
