Getting a weed free lawn without chemicals?
I am new to the forum and I joined because I have started to become fascinated with gardening now that I have moved into a house.
My question: My lawn currently has weeds growing, dandelions, crabgrass, stuff that I find unpleasant and want to rid myself of. I'm trying to find the best way to get rid of weeds and unpleasantness without totally killing the entire lawn and starting over. I plan to grow quite a few edible plants (fruits, veggies, herbs, etc.) and I want to try my best NOT to use nasty chemicals if I can avoid it. Am I able to over-seed with the grass I want and it'll smother what's currently there or is there another option I have to take?
All opinions are greatly appreciated since I'm a newbie at most of this. I've read many things on gardening and I want to be as organic as possible and I just want a nice lawn. Thanks!
