The answer to 'why is my stone walkway bare spots' is that there are several common causes, including heavy foot traffic, inadequate soil preparation, and improper installation. Bare spots can develop over time as the stones become dislodged or the soil underneath erodes, leaving gaps in the walkway.
Some common symptoms of bare spots include uneven surfaces, loose stones, and a generally unkempt appearance. To address this issue, you may need to re-level the stones, fill in the gaps with additional gravel or sand, and potentially re-lay the stones to ensure a stable, even surface. For more extensive repairs or if the underlying issue is unclear, it's best to consult a professional landscaper who can assess the situation and provide the appropriate solution.
