Turn to landscape timbers for an easy DIY lawn edging that keeps grass from invading planting areas. To install, you’ll need to dig down a few inches to create a stable footing for the timbers. To help timbers last longer, it’s a good idea to add a layer of landscape fabric topped with gravel between the timber and soil. Nestle timbers into soil as deeply as you want, but try to keep them raised at least a few inches to create a grass-proof barrier. Use a wider timber (6 inches minimum) if you’re stacking timbers and want them to serve as seating.
