This is my first year and I am trying to go legit in the first year but I have to make the money to get there. I have gotten 5 mulching jobs from doing just one. The problem I am having is knowing what to do to control the weeds prior to laying the mulch without using the black weed blocker. I know I have to be certified to use chemicals but is there something someone can tell me to do without busting on me for not being certified yet. Any help is greatly appreciated.
