Chris: Thanks for a really good ... and timely tip! I'm going to be rearranging some garden edging in the very near future and this is such a great idea!

Great tip! I have a lot of work cut out for me, as I haven't done it yet and I have tons of rocks, stones, pavers etc...

Good tip. I wish the folks who used brick and mortar on the edging of my garden had thought of that. I'm constantly digging out Bermuda from the beds. I wonder if I can dig down 6 inches or so and place a vertical liner of sorts against the bed side of the brick installation.

I make raised bed walls out of thin concrete pavers stood on end - 3/4" or 1" thick, and standing 8 or 12" tall. Sometimes the corners or edges dry out too fast.

Then I tip the pavers away from the bed and lay some plastic between the pavers and the soil, then lean the pavers back into place to hold the plastic. That keeps air and water from passing as freely between and through the pavers.

I cut the plastic from big bags of soil amendments that would otherwise have been thrown away. And I keep the plastic below soil level so it isn't unsightly.

I hadn't thought of it, but it may also help with invading weeds as your tip explains. In many beds, I still have so many weeds that I can't tell if some are coming through the walls.

These are very new beds, that have never been sufficiently mulched.

I've been doing this for 20 years and it works great keeping weeds out. In my picture the weed barrier shows, but in reality, I make sure it's buried with soil when I'm done.

Rick, great idea recycling your bags this way!
