The answer to 'lawn mowing has weeds' is that weeds in your lawn are a common problem caused by a variety of factors, including poor mowing practices, soil compaction, and lack of proper lawn care. Symptoms may include patchy grass, excessive weed growth, and an overall unhealthy lawn appearance.
To address this issue, you can try DIY solutions like adjusting your mowing height, aerating the soil, and applying a selective herbicide to target the specific weeds in your lawn. However, if the problem persists or you're unsure of the best approach, it's recommended to call a professional landscaper who can assess the situation and provide a tailored solution.
