Hey @Gandalf70
The groundcover is a mixed culture of nitrogen-fixing plants that store nitrogen from the air in their roots, which they themselves do not consume in that quantity.
When cut down and left to decompose on the soil, the nitrogen returns to the soil.
Among the other advantages, the top layer of soil remains slightly moist and does not dry out due to light and wind.
Virtually devastated.
I work with Living Soil.
With this method, “I” don’t feed the plant, but the soil supplies it, specifically the soil life in the earth.
I feed the soil, the life within it, to keep all the bacteria and fungi in the soil happy that have entered into a symbiosis with the plant.
With this, I achieve maximum terpene complexity
and reuse the soil multiple times.
I also only throw away a portion of the leaf trimmings, as I leave much of it on the soil, which returns to the cycle through decomposition.
Basically, as it has happened in nature for millions of years.
Only nature reduced to pots.
Consistently slightly moist soil ensures a feel-good oasis for microorganisms directly under planting and mulch.
It is a long, complex path.
Search the internet for Living Soil, Korean Natural Farming, and IMO.
That explains what I do in even more detail.
Best regards
