Care For Cast Iron Planters

Decorative cast iron pieces can last for many years when cared for properly. Cast iron planters make a beautiful addition to the home flower garden, patio or entryway. Delicate pieces can even add a touch of whimsy to home décor. While proper care for cast iron planters kept outdoors requires a maintenance plan, the amount of work is minimal. Does this Spark an idea?


To prevent rust, cast iron planters must be properly coated by the manufacturer or the homeowner. There are a number of protective finishes on the market for use on cast iron pieces. If the piece comes unfinished, apply a rust inhibiting primer, paint the piece the desired color and finish off with a clear coat protective finish. For a natural look, simply apply a clear finish. Apply liquid car wax to the cast iron planter at least once a year to provide further protection. Closely monitor planters exposed to a seaside environment. Salt water quickly eats away the protective finish on cast iron pieces.

Repair chipped or rusted garden planters immediately. Use a wire brush to gently brush away any signs of rust and then apply primer, paint and a coat of protective finish. Seal all surfaces of the cast iron planter; rust spreads quickly, destroying cast iron pieces.


Thoroughly clean cast iron planters at least twice a year, preferably before and after the gardening season. Wash all surfaces with a soft cloth and warm, soapy water and rinse completely. Dry the cast iron planter, inside and outside, by hand.

Use a damp cloth to wipe dust and sand from the planter at least once a month. While completing the monthly dusting, check for any chipped surfaces, rust and areas where the finish has worn off.


Never place soil and plants directly into a cast iron planter. Keep plants in removable pots for easy removal when plants require watering. Allow excess water to drain and wipe water from the pot before returning it to the cast iron planter. Do not allow water to accumulate in, on or under the planter.

Cover the cast iron planter during inclement weather. Keep the planter in a location that provides protection from winds that blow debris, dirt and sand against it. Thoroughly wash and dry the planter before storing it. Apply a fresh coat of car wax to protect it from dampness while it is stored away.
