The answer to 'frequency of sod installation' is that most experts recommend installing new sod every 5-10 years to maintain a healthy, lush lawn. Sod is a great option for quickly establishing a new lawn or replacing a damaged one, but it has a limited lifespan of around 5-10 years before it needs to be replaced.
The frequency of sod installation will depend on factors like the climate, amount of foot traffic, and how well the lawn is maintained. In cooler climates, sod may last closer to 10 years, while in warmer regions it may need to be replaced every 5-7 years. Proper mowing, watering, and aeration can help extend the lifespan of sod, but eventually it will need to be replaced to keep your lawn looking its best.
