Outdoor Garden Planters

Metal Planters ~ for beauty that grows with age 

Outdoor metal planters are durable and often increase in beauty as they age. Whether you love the rich color of copper or the strong industrial look of steel or cast iron—the one characteristic that sets metal garden planters apart is the beauty that aging can add to their surface color and texture. Zinc planters are currently very popular as they add a dramatic, often contemporary, style to any outdoor decor of your garden landscape or on your deck or patio.

Metal garden planters are often used as ‘cache pots’—decorative containers which hold a planted plastic or resin pot inside. If you have tall or over-sized planters that you don’t want to fill with soil, insert an inexpensive plastic pot turned upside down, then add your planted container. You may still want to ensure the metal cache pot has a drainage hole, so excess water doesn’t pool at the bottom.

Characteristics of Outdoor Metal Planters


  • will not chip, crack or break
  • most metal planters often gain beautiful color, or patina, as they age
  • heavy cast iron is a good choice for landscape planters in public areas such as driveways and front yards


  • metal planters can really heat up in strong sun which rapidly dries the soil and can damage roots
  • are non-porous, making addition of adequate drainage holes important
  • many are heavy, so consider their weight carefully when planning their location
  • in extremely wet regions it is a good idea to coat metal planters with a non-toxic rust inhibitor
