Sod or Seed?

Seed: Seeding can be done in the spring, however weeds and high summer temperatures often reduce the chance of success. Most annual weeds that compete with new grass seedlings germinate in spring. In addition, the short growth period in spring allows little time to develop a root system to survive the summer heat. For best results seeding should be done in late summer to early fall. Seeding done during these periods allows enough time for the grass seed to become well established before winter. Watering the new site is very important. For the best germination, be sure that there is moist soil to a depth of 2-4 inches. After seeding, water only as needed. Some drying during the day will not harm the seed, it may actually enhance germination. Gradually taper off on watering as the grass grows larger and the temperature cools. Ordinarily, 6-12 weeks are needed for establishment. It takes a full season for the new lawn to be a mature and durable turf, able to withstand traffic.

Sod: Sod should be laid as soon as possible or within 24 hours of delivery or pick up. Keep the sod moist but not saturated until firmly rooted in the soil, then gradually reduce watering. In 2-3 months, it can be treated as an established lawn. Aerification may help to prevent layering caused by peat or soil that came with the sod; aerate after establishment in the fall to at least a depth that goes through the sod and penetrates the existing soil layer.
