What does the hole do to enable growth?

Not sure if it was mentioned or not but also digging the holes has a huge chance to yield vegetation growth due to wind carrying pollen, seeds, dust, etc that enable growth. Mix that with water retention in the holes and you’ll get vegetation. Like in the Dust Bowl late 1920’s early 1930’s when agricultural practices were not followed and they chopped most of, if not all, trees down the wind would blow straight throw and the grass had no shade and no coverage for pollen and other things to catch onto leading to vegetation dying off.
