My take on this is if you don’t get every single person on board, it leads to more problems. As I’ve said in another thread, I’m not a yard Nazi, a dandelion here or there is no big deal. I usually leave clover be. It’s only creeping Charlie I get upset about. But, I do have 2 yard Nazis on my culdesac. We had a neighbor who did his version of no mow summer. Said he wouldn’t spray his dandelions and other weeds because it was bad for the environment. In the end, his antics led 4 other houses to hire spraying/weed control services. I have a feeling he added a lot more chemicals to the environment second hand than he would have if he just kept things under control.
Finally, in late June, his wife called a service to come in and get it under control. I believe they were threatened with a fine From the village. It’s not that hard to keep a decent yard with little chemical use, but when things get out of control, your weeds spread to neighbors who will dump a bunch of chemicals on theirs to keep them pristine.
