Do cast iron outdoor flower boxes require regular sealing?
Cast iron outdoor flower boxes are durable and stylish, but they do require regular sealing to prevent rust and maintain their appearance. Over time, exposure to moisture and weather can cause cast iron to corrode. Applying a high-quality sealant every 1-2 years helps protect the metal, ensuring longevity. Before sealing, clean the surface thoroughly and remove any rust. Use a rust-inhibiting primer if needed, followed by a weather-resistant sealant. Proper maintenance keeps your cast iron planters looking beautiful for years.
