Recently, I made my wife an oak desk, which created alot of sawdust. I used my shopvac to clean it up. I started to just throw the sawdust away in the trash can, but I wanted to ask around if sawdust harms lawn grass. I thought about sprinkling it around the yard to provide nutrients, but I'm cautious. It's mainly from red oak boards, so there's no pressure treated lumber. Any feedback?
