I lived in a neighborhood where the lots were back to back. If you had a dog or a pool, you had to have a fence. I had neither and had no fence. The people living behind me had a dog and a 1M chain link fence. On Thursdays, the HOA would inspect the properties and write up anyone whose grass was too long. The neighbors behind me would mow their front yard, but the grass in the back yard was always too long and would grow up into the fence. Shouldn’t have been my problem, but the “inspector” was a 5-foot tall woman who weighed about 150 kilos and was far too lazy to actually get out of her car and SEE where the grass was too long. She wrote me up for having grass in “my” fence and the grass in the back yard being too long, but as I said previously, it was actually my neighbor's fence. I tried talking to the neighbor, but he never did anything about it. Did you know that Miracle-Gro sells an inline feeder that connects to a garden hose and automatically dispenses its product? I acquired one of these feeders and several boxes of their product. I placed ratchet sprinklers on the back corners of my yard and used them to water my grass, but at night I would change the settings on the sprinklers to water THEIR yard. Every night, I would run a bunch of Miracle-Gro through the sprinklers, watering their back yard. After a couple of weeks of this, the grass in their back yard was vibrant and green. And about .5 meters tall. They had to start mowing their back yard twice a week due to it growing so fast. I never got written up again for the grass being too long in my back yard, since they were now keeping their grass mowed properly. Problem solved, and I didn’t have to deal with the neighbors anymore. I don’t think they ever noticed that the greenest grass was in two arcs corresponding to the two sprinklers placed in the corners of my yard.
