" and using small stone to set the path, which would then be set with landscape glue. "

What is landscaping glue? Pebble walkways are typically loose set from what I know.

Thanks to all who've responded. I would have amended my prior post, but not sure how to do that - thanks for understanding. As for the landscape glue, my landscaper said it is used to set small stones in walkways otherwise the stones will constantly be on the steps like the mulch is now. Landscaper did suggest the metal edging but we are concerned that if someone steps off the path and lands on it, that it could cause injury....

We have it in our backyard with kids and haven't had any issues, it is not sharp

Ive never heard of landscape glue but we have a 4x6 wood edging on a front path that works well. In our backyard we had river rock with plastic edging around our poured in place pavers but our dogs spread the rocks everywhere so we took out the edging and changed rocks to a crushed rock. The dogs can still spread it some but otherwise it doesn't move.

Looks like the stone path was set too low. They should be raised up proud of the mulch.

Houssaon got it, as usual.

Thanks Houssaon - with regards to raising the stones, is that done be regrading the area? If not,, if only raising each step (presumably by adding soil underbeath), won't the soil ultimately wash away causing same to drop over time? We already have plantings in so trying to determine best course.

I'm thinking a little elbow grease with a broom is the answer - get out there and sweep the mulch back where it belongs!
