Natural stone retaining walls are low-maintenance, but regular care can help keep them in optimal condition for years to come. Inspect your wall periodically for signs of shifting, cracks, or erosion, as natural settling or weather conditions may cause minor movement over time. Any significant movement should be addressed early to prevent further damage.

Weeds or moss may grow between the stones, which could eventually weaken the wall's structure. Removing this growth by hand or using a natural herbicide can help maintain the wall’s integrity. Cleaning the stones with a soft brush and mild soap solution is typically enough to remove dirt, algae, or stains, particularly in shaded areas that remain damp.

Ensuring proper drainage is key to maintaining the longevity of your wall. Check that drainage systems, if installed, remain free from debris to prevent water pressure from building up behind the wall. Avoid placing heavy items, like large planters or structures, close to the wall’s edge, as excessive weight can cause stones to shift.

During winter, it’s best to avoid using salt-based deicers around your stone wall. Salt can degrade certain types of natural stone over time, so opt for sand or a non-corrosive deicing product to avoid damage.
