The answer to 'seeding turning brown' is that there are several common causes, including improper watering, disease, pests, or environmental stress. The symptoms may include patchy, discolored, or dying grass in the seeded areas. The solutions can vary depending on the underlying issue, but may involve adjusting watering, treating for disease or pests, or providing additional care for the new grass seed.
In many cases, minor issues can be resolved through proper maintenance and care. However, if the problem persists or you're unsure of the cause, it's best to consult a professional landscaper who can diagnose the issue and recommend the appropriate treatment. They have the expertise and tools to properly address the problem and get your new lawn established.
