Personally, I do not like any weed block and would rather have the mulch in contact with the soil, and breaking down and improving the soil. Pre-em and Gly will help but laying down 3 to 4" of mulch is key. I do not like turning it, I would rather mulch over. The exception being annual beds. Again I have few weed problems in those and we hand pull them on full service accounts as it is no big deal in a tilled bed to pull weeds.
Duekster I have a question
I have about 6" of pine bark in mine, freshened up a couple times each sping since 2010 when I put in the landscaping now.
I didn't remove any and I took up some of the weed block around my big oak tree's because of fear water wasn't getting to them.
If not lack of water then could the 6" of bark be smothering the roots?
What Pre-em you recomend because more of the weed block is coming up and thats the route I'm going next season.
