We're in desperate need of some landscape curbing for our front flower beds. We tried the black plastic edging and that just warped and didn't hold in the mulch. Then we tried something DH came up with: slats from wood fence panels cut to size angled on top stuck in the ground. We had extra fence panels to use (although they do sell strips of wood for this purpose - see photo). It was sort of like a picket fence for our flower bushes. We set them too close and didn't allow for expansion, so they're all laying all over the place now. The ones from the store are pre-spaced with wires to make install easier, allow for expansion and to help keep them in place.
We looked into stone borders from Home Depot similar to retention wall stone. They're about $1.50 per stone and for our 80 ft. line, we'd need 2 layers which would be about $300 plus all that time and lifting. Plus it would take away from the visual height of our flower beds since 2 levels of stone would be about 8 inches high. So then we started looking into concrete edging. Typically, this is done by a professional with a concrete forming machine that he just runs down the outline of the prepped border and wha-la, permanent edging to withstand the rain, sun, sleet and snow. There's all types of stamping and color options to decorate the concrete. There's even different forms to make the border a different shape.
We had 1 guy come give us an estimate, and if you know me, you know I've got to check all my options and compare prices, so we've got a 2 more companies coming over to give us an estimate. Hopefully I'll have some nice 'after' pics soon so I can do a before and after post.
