I am aiming for a clover lawn. Up until the '60s, lawn seed was a mix of grass and clover. Clover doesn't grow fast nor high, so needs less mowing, and fixes its own nitrogen, which requires no fertilizer.
Modern lawn seed contains no clover, and weed killer kills clover. Weed and feed becomes an annual event for eternity.
My lawn now is about half clover, and I am trying to raise that percentage, resulting in a low maintenance, nice looking lawn.
you have my attention, would not mind more information.
