The answer to 'lawn has weeds' is that common causes of weeds in a lawn include poor soil conditions, lack of proper lawn care, and improper mowing or watering. Weeds can be identified by their different appearance compared to the desired grass, and symptoms may include patchy growth, discoloration, and an overall unkempt look. The solution is to address the underlying causes and take steps to improve the health and vigor of the lawn, which can involve aerating the soil, overseeding, and using targeted weed control products. In some cases, it may be best to call a professional landscaper to diagnose and treat the problem.
Weeds can be a frustrating issue for homeowners, but with the right approach, the lawn can be restored to a healthy, weed-free state. It's important to identify the root causes and take the necessary steps to address them, whether through DIY methods or by hiring a professional landscaper.
