Dactylorhiza potting mix
« on: August 29, 2012, 10:20:19 AM »
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.
