The answer to 'stone walkway dying plants' is that there are several common causes, including improper drainage, soil pH imbalance, and insufficient sunlight or water. Symptoms may include wilting, discoloration, and stunted growth of the plants along the walkway.
To address the issue, start by inspecting the drainage around the walkway. Ensure water is not pooling or stagnating, as this can lead to root rot and plant death. Next, test the soil pH and amend it if necessary to create the optimal growing conditions. If the plants are not receiving enough sunlight or water, adjust their care accordingly. For more complex problems, it's best to consult a professional landscaper who can diagnose the issue and provide the appropriate solution.
