Thanks Fred.

I had a wonderful collection until about five years ago and then they were all destroyed.

There are however masses of self sown seedlings around the garden so I had hoped I was clear.

I have just started again last year with some new special ones and it looks like I still have the problem. It seems it can stay around in the soil for some years.

It's not just in the soil.
Mine were all outside in peat compost in tubs and troughs, I ditched the contaminated ones.
I'm still ditching them 3 years later, 2 pots this year outside.
All others look clear and healthy.

There is one group that has survived outside unscathed so far in a tub of Hosta.

Well so far this year I am in the clear, but I am spraying them a systemic fungicide, to ensure it does not return.

You got a very good price for your Goons collection then Fred,

I've sprayed every year but not this year after someone told me I might be killing friendly fungi. Maybe I'll spray mine tomorrow

[ronm]

Please don't .... we are very friendly,

I am using http://www.syngenta-crop.co.uk/products/switch/summary.aspx got it from a local farmer already mixed.  Not sure were you would get it from, probably a Horticulture supplier.

Mark Dactylorhiza does not need a fungus once it has germinated and produced a tuber.  But if you are concerned then cover the soil up around the stem before spraying.
