The answer to 'grass has weeds' is that weeds are common in lawns and can be caused by a variety of factors, including poor soil conditions, overwatering, and lack of proper lawn care. Weeds can outcompete grass for nutrients and water, leading to an unhealthy, patchy lawn.
Some common symptoms of a weed-infested lawn include the presence of unwanted plants, such as dandelions, crabgrass, or clover, as well as bare or thinning areas in the grass. Weeds can also make the lawn appear unsightly and unkempt.
