These fiberstone planters have been designed to combine the best of cement/stone planters, without compromising on quality or appeal. Iron bars line the pot at traditional weak points, to prevent any bowing out or cracking as the plant inside grows, and a mesh layer keeps the whole planter sturdy as a rock. A membrane prevents any leeching of materials into your chosen growing medium too. Primrose Grey Medium Outdoor Polystone Round Rimmed Garden Planter Diameter 38cm
