    I believe Dutch Elm disease is a fungal infection. It's likely that any present fungal infection will out compete anything introduced.

    Many attempts, no luck so far!

    I would be very reluctant to store or use diseased elm wood. From the RHS website:

    The fungus is spread by elm bark beetles, particularly Scolytus scolytus. Beetles breed in dead and dying elms, including those killed by the disease, where the larvae tunnel in the bark and outermost wood, forming galleries. The fungus produces sticky spores in these galleries, which contaminate the newly hatched adult beetles as they emerge. They then fly to healthy elms, where they feed on young bark and introduce the pathogen into the conducting tissue (xylem) of the tree. The fungus grows in the xylem, blocking water flow and causing rapid wilting and death. It can spread rapidly down rows of hedgerow elms through root grafts formed between adjacent trees. https://www.rhs.org.uk/advice/profile?PID=154

    By storing the dead wood you are providing a habitat for the pest that spreads the problem.

    Use freshly cut wood, preferably a hardwood. Tree's contain natural fungicides as a defence. Advised you give it 5+ weeks until you inoculate the wood with mycelium.


    From my observations last year was not particularly good for fungi.

    This was my Shiitake crop;

    You can achieve several flushes of fruiting shrooms by soaking the wood in dechlorinated water (water butt filled with tap water left over 24hrs) and giving each log one violent bash to tigger the fruit pinning (primordia).

    Good afternoon,

    When using the log and plug method, you have to remember that it takes a long time for the mushroom mycelium to grow through the log, the bigger the log, the longer it takes.
    The biggest failure comes when you've not realised your logs have dried out, smaller logs dry out quicker than larger diameter logs, they need to be regularly wetted.
    All my plug/logs are in my hugelkutur, keeps them wet and feeds the hugelkutur bed.
    Your best chance of success it, especially with oyster mushrooms is to grow them in bags of sterilised straw or wood chips. works really well in my opinion.
    You can use pelleted straw or wood, hardwood is better than softwood.
    Im not too sure exactly about Elm, but I would definitely give it a go, worth a shot. Most wood eating mushrooms are adapted with the necessary enzymes to utilise as a nutrient source, just remember to keep you logs regularly wetted, especially small diameter logs.
