Grow a variety of plants in this large flowerpot. Made from UV-resistant, durable linear, low-density polyethylene (polyresin), the round garden planter is designed for lasting use and can be used indoors or outdoors. The outdoor flowerpot features an innovative double-wall design. The outer wall can also be filled with gravel or sand to add weight for windy conditions. Add a drainage hole to the outer wall by drilling with a 1/4" bit on the marked location on the bottom of the planter to ensure proper drainage. If a drainage hole is added, be sure to use a saucer beneath the planter when using it indoors to prevent leaks on the floor or other surfaces.
