I'm interested to know why you think that plants grown in inorganics are more likely to suffer frost damage than plants grown in organic mediums in pots.
Ok, so are you are saying that the clay is acting like the inorganics the rest of us are using?
Species from the macranthos and tibeticum complex will struggle in beds with the winter wet..
what exactly are you describing when you talk about adding hammered clay to water? I think I'm missing the point.
I'm assuming that the clay particles go into suspension and 'sort of 'dissolve to make a sort of gloopy mix. As clay is made up of very fine particles then this is not entirely unexpected.
How does this fact help with the culture of cyps in pots?
1/3 heathland soil1/3 garden soil if good soil with ,natural humus 1/3 river sand (only this one)and I always add a little perlite
Corrado, Heathland soil is a traduction of "terre de bruyère" in French form heather = bruyère in FrenchMy climat is the climate of Ardennes in France (T° min = -22°c and max = around 35°), it' rain a lot and i need drained medium of soil.River sand, it's very very fine sand i found that neat the house in Belgium.The exposition of the garden is medium but i have many area with protection of the sun in semi-shading area.
