Hello errodr, I think that the stepping stones will eventually "sink". You should consider using "Dry sand-and-cement bed" under the stepping stones and have a Weed Barrier Cloth over the sand before applying the mulch on it. However, why not consider to not use mulch but a more Japanese solution like gravel or (small) crushed stone. Also worth considering is the use of a band to enclose the pathway. A natural (look) material like (cut) granite would be best suited. This would also easy the lawn maintenance. Have a look at my front entrance path (not in a lawn though ! also http://www.karesansui.nl/html/page_compfront.htm ) Regards, Piet |
