Experiment for growing mix

[Rodger Whitlock]

So, sitting here in faraway western Canada, I am wondering, just what are these miraculous mixes?

It goes without saying that neither the Melcourt Sylvamix formulations nor the Neudohum are sold in Canada, but I'm wondering if perhaps we have a similar product?

In particular, I'm wondering if "Sea soil" might be close. It's a mixture of sawmill waste and fish waste composted together to make a very black product of rather coarse texture. I recently inherited plants of Dactylorhiza foliosa planted in a three-way mixture of Sea Soil, fine coir, and granite grit.

hello Roger,
at least I think, there is no real "miracle" behind that mixtures.

as far as one can determine, all those mixtures consist of fine grade composted fir bark, different grades of cocos fibre, (special treated) wood fibres, and little of natural compost and "fertilizer for 6 months", pH adjusted at 6.

I asked the Neudohum manufacturer, and  they did not state there are any fungi added to that "composition".

The only  "miracle" was the idea of "berthold" from Germany in terrorchid forum, to use that kind of organic soil for growing terrestrial orchids.

the Neudohum material is not sterilized, because sometimes "little black flies" come out of the material after planting.................... 

so, I think, you can mix your own "Neudohum/Silvamix", using that ingredients, which I mentioned above

But be cautious, it sometimes becomes "soggy"...............
(therefor I always add about 50 to 70 % Perlite or something like that)

cheers
