How to Help New Grass Grow

Overview

Establishing new grass can be a challenging task. From the time you plant the seeds until the grass is mature, much care is needed to ensure its survival. New seeds can be easily washed away in a heavy rainstorm, young seedlings can succumb to drought or disease, and even almost-mature grass can fail to thrive.

Step 1

Water the grass to keep the seedbed moist at all times. New grass should be watered three or four times per week for about 20 to 30 minutes per watering. Water in the morning to lessen evaporation effects of mid-day sun. New grass does not have a developed root system. The roots are shallow, and once they dry out, the grass will die.

Step 2

Spread a starter fertilizer on your new grass. Starter fertilizer contains high levels of nitrogen and phosphorous. Nitrogen promotes vigorous shoot growth, while phosphorous promotes root growth and development. A starter fertilizer will have a ratio such as 10-20-10 or 5-10-5 (nitrogen, phosphorous, potassium). The bag will tell you how much fertilizer to spread over your lawn.

Step 3

Mow your grass every five to seven days. Don't remove more than one-third of the grass blade at each mowing. When you remove too much at once, the grass becomes weakened and subject to possible scorching.

Step 4

Prevent dogs from urinating on your lawn. Urine damage is a very common problem on home lawns. Urine contains a high level of nitrogen that can easily kill the grass.
