I really fucked up my lawn by putting red clover down in addition to white. Red clover is perineal and grows tall and falls flat on its side. It decays into this horrible straw like shit. I hate it. Horrible horrible decision.
Because it's sort of fucked for a few years I guess, I've been a lot more hands off with leaves. Because hey, even if it kills off some of the stuff there then that's fine by me. I think I only mowed once this year. I only blow leaves off the driveway and onto the yard.
This summer I'll see the fruits of my labor. I'm really curious to see if there are substantially more fireflies.
