How do cast iron outdoor sculptures interact with soil pH when placed directly on the ground?
Cast iron outdoor sculptures can be significantly affected by soil pH when placed directly on the ground. Acidic soils (low pH) accelerate corrosion, causing rust and weakening the metal over time. Alkaline soils (high pH) may slow corrosion but can still lead to surface discoloration. To protect sculptures, consider using barriers like gravel or epoxy coatings, or elevate them on pedestals. Regular maintenance, such as cleaning and applying protective sealants, can also extend their lifespan. Understanding soil pH helps preserve the beauty and integrity of cast iron art in gardens and landscapes.
