Installing a garden edge is an easy and effective way to ensure that your garden stays orderly and that your lawn doesn't creep over. A garden edge can also be a big help in keeping weeds from getting into your garden and ruining your beautiful plants. You will need to measure around the perimeter you want to enclose and buy a corresponding amount of edging. After that, it's as easy as digging around the area with a spade and putting the edging into the ground. Then you just fill in dirt around the bottom and your garden is protected by edging.
