Garden planters are popular containers made of such materials as
bronze, wrought iron, brass, cast aluminum, stainless steel, and
copper. If you are shopping for an indoor pot or a container to use
on your patio, deck, in the garden, or for window boxes, hanging
baskets, or wall hangers.
Metal garden planters are sturdy and long-wearing, retain moisture
well, help prevent insect infestations, and are rust-proof. The
heavier metals can contain shrubs, vines, and small trees, but if
you want to be able to move full soil and plant-filled pots and
planters, choose a lighter metal such as cast aluminum or copper.
