The answer to 'lawn mowing bare spots' is that there are several common causes, including poor soil, lack of sunlight, compaction, and improper mowing. Bare spots can be a symptom of these underlying issues. The best solution is to first identify and address the root cause, then overseed the bare area to establish new grass growth.
If the bare spots are due to poor soil quality, you may need to amend the soil with compost or topsoil. Lack of sunlight can be addressed by trimming back any overhanging trees or shrubs. Compacted soil should be aerated to allow water and nutrients to reach the grass roots. And improper mowing, such as cutting the grass too short, can also lead to bare patches.
