The answer to 'frequency of sod' is that sod should typically be replaced every 5-10 years. Sod provides an instant green lawn, but it has a limited lifespan and will eventually need to be replaced as the grass becomes thin, patchy, or damaged. The exact frequency will depend on factors like the quality of the sod, how well it was installed, and how well you maintain it through mowing, watering, and other lawn care.
Replacing sod every 5-10 years helps ensure your lawn stays lush and healthy. Over time, the grass will become less dense, the roots will weaken, and the sod will become more susceptible to weeds, pests, and disease. Replacing the sod gives you a fresh start with new, vibrant grass that can thrive for several more years before needing to be replaced again.
