Best edging for flagstone walkway? Steel? Aluminum?
I am laying a dry-laid flagstone walkway this spring. It's bordered by turf on one side, and against a garage on the other. I'd like to use an edging to keep my base materials from migrating and the grass out as much as is possible. I don't like plastic, and I don't want to use cobblestones down one side only (unbalanced look) so I'm looking for the least visually obtrusive option. Am I right to think metal is the way to go? If so, steel or aluminum? Is the Home Depot stuff OK or should I seek out a better product at my local landscaper supply place? Any tips?
