This section shares how to successfully care for new grass seed and growth following the water line replacement construction work. When the project is complete, the contractors will lay new dirt, grass seed, and straw to help restore lawns, but it is up to residents to continue the maintenance with watering and weeding the area to promote the grass growth.

Tips for Homeowners Caring of a Newly Seeded Lawn

1. Light & frequent watering is best

Newly seeded lawns need to be always kept moist. It’s important to water the lawn daily with sprinklers to keep the soil damp but not waterlogged. Watering the lawn for each day for about 10-15 minutes (depending on sprinkler coverage) is a good guideline. If the weather is over 65 degrees and sunny, watering the lawn a second time can help keep the lawn moist. Avoid overwatering, as this can cause the seeds to float away or promote fungal growth.

2. Minimize traffic on newly seeded lawn

It’s important to avoid heavy traffic on the newly seeded lawn. You may walk on the lawn to move sprinklers but try to minimize other foot traffic. Pets and equipment should be kept off the lawn until the grass is well-established.

3. When to weed and rake

Newly seeded lawns are vulnerable to weeds, so it’s important to keep the lawn free of weeds. Hand-pull any weeds that may appear, or use a herbicide labeled for use on newly seeded lawns. Do not rake or remove straw from the newly seeded area. The straw will decompose naturally.

4. Wait to mow new grass

The newly seeded lawn should not be mowed until the grass reaches a height of at least 5-6 inches and grass covers at least half of the seeded areas. When mowing, keep the blades high and avoid cutting more than one-third of the grass blade length. After the first mowing, continue to keep the lawn between 3-4” during establishment. Avoid mowing when it is hot (above 85 degrees) or dry.

5. Fertilizing not necessary yet

Typically when grass is seeded after a construction project, the appropriate amount of fertilizer was also placed. Fertilizer usually does not need to be applied during the first year of having a new lawn, unless otherwise instructed. After the first winter, fertilize the area on the same schedule as the rest of your lawn.

6. Be patient & persistent

Growing a healthy lawn takes time and patience. It can take up to 6-8 weeks for the grass to establish, so it’s important to continue to care for the lawn during this time and follow these steps for the best results!
