You can fertilize new sod 4 to 6 weeks after laying it to allow the grass to develop its roots and anchor well to the ground. Your grass will absorb the nutrients from the fertilizer better if it has developed roots well.

Timing is of utmost importance when it comes to fertilizing sod after the installation, as it will determine if your lawn benefits from it or suffer negative effects of premature application.

If you laid sod in winter, wait until spring when it greens up before fertilizing it.

Whenever possible, use a controlled-release or slow-release Nitrogen form, especially in fall and spring.

It’s best to fertilize your lawn in the morning to benefit from the cooler temperatures, absorb the dew, and let the soil absorb most nutrients.

What Is The Difference Between Starter Fertilizer And Regular?

Starter fertilizer for grass is specially formulated for newly-seeded lawns and sod. It is high in phosphorus, which is essential for root growth and establishment, but typically contains lower levels of nitrogen and potassium.

The purpose of starter fertilizer is to encourage the growth of strong roots, so the lawn can become established quickly and effectively.

Regular fertilizer, on the other hand, is designed for established lawns. It typically contains a balanced ratio of nitrogen, phosphorus, and potassium to promote overall growth and health of the lawn.

This type of fertilizer is designed to provide ongoing nutrition to an established lawn and support its overall growth and health.

Generally, the main difference between starter fertilizer and regular fertilizer is that starter fertilizer is designed for newly-seeded lawns and sod, while regular fertilizer is designed for established lawns.

When Can I Begin Transitioning My Lawn To A Regular Fertilizer?

Generally, you can transition your lawn from starter fertilizer to regular fertilizer after 30 days of installation. The fertilizer box you choose will depend on the season you installed the grass.

For instance, you might need to use the fall fertilizer box to establish your new lawn in the summer. This box will help get your yard ready for winter dormancy and recover from the summer heat.

Seasonal fertilizer boxes differ because soil conditions and temperatures change all around the year. This means your lawn requires specific nutrients at various times, so you need to pick the right one, depending on the season to ensure fertilizing sod after installation goes well.

Look for a fertilizer plan equipped to meet your lawn’s changing seasonal requirements.


Fertilizing new sod is an important aspect of maintaining a healthy lawn. The right type and amount of fertilizer can help the sod roots establish properly, promote growth, and prevent disease and pest problems.

However, it’s crucial to follow the manufacturer’s recommendations for application and timing to avoid over-fertilizing, which can lead to fertilizer burn and other issues.

If you’re unsure about the best fertilization practices for your new sod, consider seeking the advice of a professional landscaper or lawn care specialist.
