What are the effects of bird droppings on the patina of stone outdoor planters?
Bird droppings can significantly impact the patina of stone outdoor planters, altering their appearance and longevity. The acidic nature of bird excrement can erode the surface of porous stones like limestone, sandstone, or concrete, leading to discoloration, pitting, and a loss of the natural weathered finish. Over time, this can weaken the structural integrity of the planter.
To mitigate damage, regular cleaning with a mild, pH-neutral solution is recommended. Sealing the stone with a protective coating can also help preserve its patina. Understanding these effects ensures your garden decor remains beautiful and durable for years to come.
