We built this mound about 5 years ago and it produced great after little over 3 years,so don't waste those logs and brush,they make great natural fertilizer and fantastic water conservation.
Watermellons grown in our mound, never watered it or fertilized .
Had illness in family so had to stop for awhile but it stlll works after about 6 years now.
First I dug down abour 3 ft. They threw in some logs I hauled using a hang truck ,then put brush on top of logs, sand brush and covered with sand. mine is only about 15' long and 3 ' W. since I did it by hand most people use heavy equipment plus I was in my 60s.
