However, the thing that's got me thinking right now is her potting soil mix, which is composed entirely of local ingredients (though btw, she does also provide many alternative mixes). I would love to have a potting soil from local ingredients!
- 1/3 sharp or silver sand
- 1/3 leaf mold
- 1/3 soil
The core ingredient of potting soil, the heart of the matter, is soil itself, the seat of culture and the source of life. In many ways good soil is analogous to yeast in the baking world because both ingredients contain local flora and fauna and both give life to their batter. Without a baseline of real soil in your potting mix, seedlings lose their tone and vigor and fall flat.Country Mouse says: "Soil? - in potting mix!?" I've always thought that soil was exactly what you should NOT include in potting mix! It doesn't drain, and isn't sterile, and so on.
Also we don't have a lot of leaf mold here - mostly we have redwood duff and scrub oak duff, which are acidic. Nor do we have sand. I also haven't been good at all so far at composting, to generate some usable material. But - I wonder if we do have what it takes right here, to propagate plants intended to - grow right here.
I am curious indeed, and plan to investigate this topic further.
