Raised garden bed planters keep the space for gardening neat & compact with about a two foot depth but nearly four feet of length. Holds 8 cubic feet of soil to grow your own tomatoes, peppers, cucumbers radishes, lettuce & herbs. You can create a garden whether you have a small patio or a huge yard. Four sturdy steel panels interlock to create the frame by using a keyhole locking mechanism (patent pending). Corrugated stamping on each panel adds strength & the powder coated finish resists rust to give you many seasons of use. The polypropylene liner sits inside this frame, keeping soil contained & helping retain moisture. It also disassembles for seasonal storage, & the panels may be placed inside the liner bag for convenient storage.
