while I'm happy with my potting mix for my Dactylorhiza - leaf mould, soil and grit - I read so many variations on the internet and in book.
One book says
3 parts loam, 2 parts bark, 2 parts perlite, 4 parts pine duff (whatever that is) and 4 parts grit
or 4 x bark, 1 x loam, 2 x perlite and 2 x sand
Should I change? What do you use?
My self sown seedlings appear is very wet peat based pots and very gritty dry troughs. Maybe there is no perfect potting mix
-
Pine Duff is composted pine needles.
Mixture sounds far too complicated for me
-
We have no problem with our two parts sand; two parts grit and one part leaf mould mix.
Yes, those mixes are far too complicated- no need for that.
Pine duff is the accumulation of fallen needles under pine trees.

If it works for you, Mark, stick with what you are using.
It sounds like a good mixture to me. ;)
-
Dactylorhiza are tolerant of many forms of growing medium,
I use 2 parts composted bark and 1 part grit.
-
I use garden centre John Innes (as I do for 90% of my plants) and just add a bit of grit. Seems to work okay.

So would I Tony except no supplier in N Ireland sells a good John Innes
