Since it did not happen to me personally I can only pass this along - a neighbor had Bahia in his St Augustine. Bates or whoever his weed guy is told him that whoever mows his yard probably mows a Bahia yard first and when he mows the St Augustine yard the seeds and droppings from the Bahia get into his grass and start growing.

I did notice that my lawn service has two mowers. I wonder if one is for Bahia and one is for St Augustine. I will probably ask one day.
