There's so much you can learn ...
Some people suggested there's a difference between rounded/sharp grit. Suggesting the sharp one suits better alpines.
I am afraid to put too much rock cause this diminished moisture retention. I am thinking about the long periods of hot and dry that our summers seem to bring.
I am thinking also there's a difference between growing in a small crevice in a rock, with very little soil, on top of the mountain (but with enough precipitation and humidity) AND growing in a normal garden where most of the water will come from ME (again, in the summer).
Even this spring is VERY dry.
Adding to the fact that winter was dry...
it rained a couple days ago, but it was not enough.
FABRIC... I would place it for two reasons. There might be root-hardy weeds like thistle, or that grass with long underground stems/rhizomes. And If ever, I decide I need to plant something else there, I can remove the grit-amended soil knowing the limit is that fabric.
