This interlocking border and raised bed system both looks and feels like real stone, without the weight! You will find endless design possibilities with the easy to assemble Rock Lock system! Suitable all year round, these hollow walls will not crack or chip and will actually extend your growing season by insulating the soil and plants. The curving feature of this product allows for gentle corners, flower bed edging or even dressing up a walkway! Not only can this system be used for landscaping or garden edging, two sets can be assembled together for a natural-looking, 4' round raised bed. Combine with Rock Lock Straight Sections to create unique beds, or use Rock Lock End Rocks to complete straight runs, both sold separately.
