Answer: Edging can be a lot of work, especially if your soil is dense and compacted, and the sod very tough, so I don't blame you for not wanting to do it by hand! The tool you're looking for is a lawn edger. Some edgers are simple and small, such as those that attach to small garden tillers, or you can get specialized lawn edgers from rental outlets. Once you have created the clean edge, you can install edging material that creates a barrier between your lawn and flower beds.
