We can install a brand-new edge on an existing garden or maintain an existing edge in the garden. When maintaining an edge it requires less time to push back the mulch creating a trench for your mulch to fall into, a weed-whacker or line trimmer is all that is needed. There is a lot more work involved in installing a new edge on a garden bed that requires special tools and removing a fair amount of debris from the soil. It is recommended to install a new edge in the garden every spring and expect to maintain the edge throughout summer by using a hand trowel and pulling back the soil or mulch depending on what's in your garden. The great benefit of having an edge on your garden is it helps to keep grass from growing into the garden as well as trimming and mowing is much easier and in the end, it looks fantastic.
