Sub-soil nasties?

We're about to plant a wisteria and have taken up paving (all of it will go eventually) that has been sat on concrete dabs. Lifting up one of these dabs I've noticed the white root like items that could be fungal forms (hyphae?)...  are these troublesome or can I ignore?




  • The vast, vast majority of fungi are entirely beneficial and many are in fact essential, so nothing to worry about. image

    Wisteria are hungry and thirsty plants so you will need to prepare quite a large and deep hole then mix lots of well-rotted farmyard manure (which you can buy in bags from garden centres these days) and compost with the soil before planting, as the soil under the slabs will very likely be in poor condition.  This will give your wisteria a flying start and feed it for several years before you need to start additional feeding. image

    A trowel in the hand is worth a thousand lost under a bush.
  • I wouldn't worry about the fungi, but I would be worried about planting anything in that soil!. It's full of sand and cement. Nothing will take root in that it will just burn the roots of anything you plant, so I'd remove it all or as much as humanly possible and get fresh topsoil and manure in there before planting anything.

    Bob, why are the fungi beneficial  , I m not very much into fungi so just curious

     We have some on our lawn , should I leave them ?

  • Fungi are one of the few living things which can break down woody matter (mainly cellulose) into a form which plants can re-use.  They are an essential part of the cycle of life.  If all fungi died-off right now, life would quite soon come to an end on the land (it would probably continue in the sea though.)

    The parts we usually see (mushrooms or toadstools) are just the fruiting body and only a tiny part of the main fungus, which is known as mycelium and lives in the soil or inside other living things (for those species which are parasitic.)

    If toadstools are a nuisance on a lawn you can just sweep them off with a stiff brush - the main body of the fungus won't be killed by doing that. image
