I've put down fabric many times before, some times it has worked better than others. In my haste to be halfway done with the project, I just dropped mulch down on top of...if to say, flourishing grass/weeds. This area was the setting for 14 GG arbors and some accent plants.
The thought was that I would just spot treat with glypho, though now I'm scared straight of getting any on my lot of trees. (used 1gallon tank with a cone and smothered each area, then sprayed.) I can hand paint but, but maybe there's another way?
Do I rake back the mulch, lay fabric?
Just add more mulch? (it is a very thin layer, not even 1")
Growth through the mulch can get pretty nutty if I don't control it. This area is only a month old, and I've already spot treated initially, which is showing results in some areas.
