Hey guys - usual deal here: first time home owner, new to gardening, etc - we have a small, circular belgian-block enclosed garden in our front yard that has been totally over run with weeds. I pulled out the large weeds and got as much of the roots as possible. There are a lot of small weeds still left and some old mulch in there. I read about "smothering" on this site with newspaper and mulch and would like to go in that direction - should I till the soil to tear up the small weeds I can't get by the roots? Or just cover them up and wait 6 weeks for it all to die? Should we spray it with an chemical first? We will likely plant a tree out there and maybe some small bushes around it. Any advice you can give would be great.
