The answer to 'how to maintain sod installation' is to follow a regular maintenance routine to keep your new sod healthy and thriving. This includes mowing, watering, fertilizing, and aerating the lawn on a consistent schedule.
Start by mowing the sod at the recommended height for your grass type, usually 3-4 inches tall. Water the lawn deeply 2-3 times per week, providing about 1 inch of water each time. Apply a balanced lawn fertilizer 2-3 times per year, following the product instructions. Finally, aerate the soil 1-2 times per year to allow air, water, and nutrients to reach the grass roots.
