The answer to 'how to maintain sod' is to properly water, mow, and fertilize your lawn on a regular schedule. This will help keep your sod healthy and looking its best. Start by watering your lawn deeply 2-3 times per week, providing about 1 inch of water each time. Mow the grass to a height of 3-4 inches, removing no more than one-third of the blade at a time. Apply a balanced lawn fertilizer 2-3 times per year, following the product instructions carefully.
In addition, be sure to aerate the soil annually to improve water and nutrient absorption. You should also address any issues like bare spots, weeds, or pest infestations promptly to maintain a lush, green lawn. If you're unsure how to properly maintain your sod, consider consulting a professional landscaper for guidance.
