I'm about to undertake my first landscape DIY project. We have a grass area that is ruined and pretty much all weeds. By weeds I mean super mega weeds with stocks 1-1.5" think. Our plan is to till the area rake out all the weeds and garbage and then put down wood chips. There will be a play structure put in also. I have a few questions.
I will need to put down about 3" of wood chips. Should I compact the loose tilled soil to get my required depth or remove the 3" completely?
Will Landscape plastic sheets be necessary to combat future weeds?
Thanks for any help.
