Just as the subject line states...I have a play area that I built for my kids (We are about 20 miles southeast of Raleigh, NC) and the play area was filled with mulch. (Its 30 feet by 20 feet, and the mulch is maybe 4-5 inches deep.)weeds
KEEP GERMINATING and growing
IN THE MULCH! Its your good ol' fashioned wood chips and the like.
I put down roofing paper under the mulch to prevent anything from coming up through the soil.
I'm hesitant to spray with weed
killer, since my kids play there...so...uh...any ideas?
