The answer to the frequency of stone walkway maintenance is that it typically needs to be done every 2-5 years, depending on the climate and usage. Stone walkways are a durable and long-lasting landscaping feature, but they do require some periodic upkeep to keep them looking their best.
Over time, the stones can become uneven, weeds can grow between them, and the mortar or gravel base can shift. Regularly inspecting the walkway and addressing any issues can help extend its lifespan. This may include resetting loose stones, removing weeds, and refreshing the gravel or mortar as needed.
