To repair sod that is dying, lift the affected pieces of sod, and re-lay it to eliminate air pockets. In hot, dry or very windy weather, increase the watering schedule, and water the lawn at night to ensure the moisture doesn't evaporate quickly. If watering doesn't resolve the issue, reseed the affected area, water the lawn frequently, and avoid mowing the lawn until the seed is well-established. Apply fertilizer after the sod revives.Continue Reading
Yellow or brown spots on sod typically indicate a need for more water. Water the lawn to a depth of 4 to 5 inches below the sod during the first one to two weeks after the installation. Continue to water the lawn frequently until the grass roots extend into the soil. After the grass is established, water the lawn to a depth of 1 to 2 inches.
If brown spots occur as a result of pests, such as insects, treat the lawn with a pesticide, apply grass seed and fertilizer to the dead sod, and thoroughly water the affected area. In general, yellow sod is repairable, while sod that has brown, brittle grass requires reseeding to repair the damage. Do not apply fertilizer to dying sod to revive it, as this can cause further damage to the root system.Learn more about Landscaping
