Getting Back To Nature With Planting Beds

Wall: Ortana, Greyfield Pavers: Avenue Series, Greyfield

Planting beds are an easy way to provide pockets of colour and life to a yard, which makes the area more inviting and appealing. Defined planting areas also help protect plantings by discouraging pedestrians from walking in the area, and plants tend to be healthier and more productive as one can control the quality of the soil and water drainage. For Planting Beds enclosed by taller walls (where geogrid reinforcement would typically be needed), Multi Depth Gravity or Stabilized Backfill walls can be used to prevent any conflicts with tree root balls. The diagram below shows how the stabilized backfill can be installed in a wedge configuration to accommodate plantings, while the photo adjacent is of a Proterra TM Multi Depth Gravity wall installation.
