I live in WV and have a tall fescue lawn. I typically fertilize about 6 times a year with Scott's. Two weeks ago, my neighbor, in the heat of the summer (it's in the 90s here) applied 23-0-0 pelletized urea to his lawn. It rained about an inch the day after the application, and now he has the darkest, greenest grass I have ever seen. I really don't know a lot about how fertilizer works (I know a little), so I thought I'd ask you guys about the potential risks of me applying the same thing to my lawn. I've heard it's preferable to feed your lawn as little nitrogen as possible. Is that right? Currently my lawn is suffering from brown patch and stress from the summer. It's like this every summer, and in the spring and fall it is the envy of the neighborhood. But it seems to look worse than other lawns during the summer months. Any advice?
