Wheels: Includes 4 casters (2 standard, 2 locking), each designed to fit easily into the caster socket integrated into the bottom of the EarthBox® gardening system.
Mulch Covers: These magical little covers are so simple, yet without them your EarthBox would be incomplete-they are one of the secrets to your gardening success. In addition to keeping unwanted weeds out, they help keep water and nutrients in, all while insulating your EarthBox and protecting it against the elements so your plant's food supply doesn't wash away.
