This is a re post of another of my favorite posts, it was titled, "A garden hint that you might not have heard about before." It really does work, give it a try next summer.
Here's one garden hint that you might never have heard before. We live in a condo, and it's pretty much community living. Flush your toilet when your neighbor is having a shower, and hear them yell. "Oh well, maybe they shouldn't use so much hot water". Sound carries here. And loudly. So when our younger neighbor, and his twenty something, party hardy type, of friends decided to hang out on the deck right beside our bedroom window all summer, all night, every night. We decided that we had to take action. We took all the appropriate methods, speaking with them, begging them to stop, banging on the walls, and writing letters to council. All to no avail. Then late one evening I was fertilizing with fish fertilizer, and realized what a huge stink it was giving off. And how unpleasantly it lingered in the air for hours. So after that, every time the noise got too much for us, I would mix up a very strong batch of fish fertilizer, and water to my hearts content. With groans of disgust the party goer's would run for the indoors. And we could enjoy our quiet evenings again. So that's my tip for noisy neighbours, fish fertilizer makes a great Party Pooper!
