The answer to 'sod installation bare spots' is that there are several common causes, including poor soil preparation, improper watering, heavy foot traffic, and pests or diseases. Symptoms can include patchy, thinning grass or exposed soil. Solutions may involve repairing the underlying issue, overseeding, or re-sodding the affected areas.
For small bare spots, homeowners can often address the problem themselves by identifying and fixing the root cause, preparing the soil, and laying new sod. However, for larger areas or more complex issues, it's generally best to call a professional landscaper who can properly diagnose and resolve the problem.
