Plant the plugs on 12-inch centers. This will give the grass enough room to grow and fill in completely by August or September
Before planting, make sure that the ground is well saturated with water. This will help to prevent the plugs from drying out during installation. You can also apply a light application of organic fertilizer, such as alfalfa meal, dried poultry waste, corn gluten, or sea kelp.
Gently remove the plug from the plug tray by pushing it up from the bottom. Do not pull it from the top, as this may break off the roots. Insert the plug into a hole that is 1 inch deep and gently press the soil around it.
Water the plugs thoroughly after planting. You may need to water them 2-3 times a day for the first week. Gradually reduce the watering frequency as the grass becomes established.
