Answer: There are so many choices! I think the factors in determining which product and style you use will be your budget, and the look you're going for in your garden.
You can choose from:
Wood ? Styles range from natural finish to decorative "fence" versions. Landscape timbers and railroad cross-ties are also popular for larger areas.
Metal ? Gives a commercial look and lasts practically forever.
Plastic ? Available in rolls or decorative "fence" styles.
Stone, brick or concrete - Gives a more formal appearance. Use precast concrete or brick in a sawtooth/zigzag pattern.
Properly installed, any of the available edging materials will do a good job in keeping grass out of your flower beds.
Best wishes with your landscape!
