Yeah, I'm in pretty much the same boat. I'm biting the bullet and
edging the borders using an edger, and then making a v shaped trench
about 3" across. Not sure if I'm going to install an edging material
yet. I'm dropping newspaper and then mulch on existing grass.
I have four inch steel edging around all my beds, but I also have a bermuda
lawn, which find that edging height a minimal challenge. Every three to four
weeks I mix up a sprayer full of RoundUp, which I use to beat back the
invading grass. Occasionally a stray weed comes up through the mulch, but I
pull them or spray them with RoundUp if I happen to be edging the bermuda at
the time. This is effective when I am diligent about staying ahead of the
invading grass or weeds.
Hello again and thanks to all who have responded. The consensus seems to be
that a trench should be dug to separate the mulch from the lawn. The lawn
should then be edged to keep the trench clean. This should be do-able for
me. I can start small with a couple of the worst mulch beds. I have quite a
few some don't seem to have the problem.
I've seen the Black and Decker LE750 hog edger. This is an electric edger
that can supposedly dig trenches as well. It seems to go for around $89. Has
anyone used this thing and can I cut the trenches with it or should I get a
professional to do that? Maybe I'll start a new thread asking about this.
A few people mentioned using newspaper to smother the grass and then mulch.
I'll try this as well since digging the grass out is very difficult.
Thanks again for all responses.
