Edging is the best way to keep your mulch from scattering. Incorporate one of several edging techniques into you landscape design to contain your mulch and improve the performance of your plants, trees, or shrubs.

Plastic edging is cheap and easy to install. The draw back is that the edging will only contain a few inches of mulch.

Precast concrete edging
