I keep coming across references in various places to stone/rock "mulch" around trees or shrubs as a unique method of water conservation or even harvesting.
The thing that most piqued my interest was the concept of the rocks condensing/concentrating the dew and feeding that down to the soil.
I've read other people talking about other just general water conservation benefits along with heat radiation, soil cooling, etc.
My question is whether the dew "harvesting" action will be effective in a temperate climate? I guess I'm showing my ignorance of biophysics/chemistry a bit here.
Would love to hear anyone's experience with rocks in temperate zones. I'm thinking larger stones, baseball-size or larger.
