You don't know my neighbors, at least one of them. Talk about "frugal". He waters his outside plants with a pot. He has a hose and I once asked him why he takes pot-after-pot-after pot of water from the house to do his watering. He said using a hose would waste water! His front and side yard is Bermuda grass, and the sod was paid for by his son. I don't know why his son didn't sod the back yard as well.
My neighbor moved here from a town in the Mississipi Delta and he still has the old home there. He has made countless trips (200 mile round-trip) back to that house and brought back thousands of sprigs of grass to plant in his back yard. The problem is that it is St. Augustine!
I and the neighbor on the other side of him have Bermuda. Now, every summer, I take a flat-edge shovel and cut a line down our property line and remove all the St. Augustine grass on my side of that (cut) line. What a pain!
I won't even talk about the weeds in his yard.
Fire ants in his yard is the least of my problems.
