When to Plant Grass Seed in Nebraska: Best Time to Plant

Planting grass seed is an essential part of maintaining a healthy lawn. A well-maintained lawn adds beauty to any home, increases its worth, and helps to conserve the environment. Not only does it enhance the look of your property, but it also offers several ecological benefits. 

A healthy lawn decreases soil erosion, purifies the air we breathe, and reduces noise. Planting grass seed helps create a thick, lush green lawn, which in turn provides a natural air conditioner for your home, saving energy and resources.

Why Plant Grass Seed?

Benefits of a Healthy Lawn

A healthy lawn has several benefits but the most important one is it prevents soil erosion. During storms, rainwater can flood your backyard and erosion can cause serious damage to your property. 

A healthy lawn absorbs the water and slows down its speed, preventing soil erosion. 

Healthy grass helps to purify the air and diminishes noise and dust. Plus, a strong lawn is a natural air purifier, absorbing carbon dioxide and releasing oxygen.

Choosing the Right Type of Grass

Choosing the right grass type for your lawn is critical. The type of grass you choose should depend on its use and your location. 

In Nebraska, cool-season grasses, such as bluegrass, fescue, and tall fescue, work best. 

These grasses grow quickly in the early spring and the late summer, and establish deep roots that can withstand extreme temperature fluctuations.

Grass Seed vs Sod

When it comes to planting grass, there are two main options: grass seed or sod. Sod is mature grass that is rolled out in your lawn. 

It provides instant gratification when it comes to the look of your lawn because you can have a fully grown grass immediately. 

It’s more expensive than planting grass seed. Planting grass seed takes a bit of time and patience, but it’s much cheaper than sod. 

Plus, seed will germinate and establish roots over time for a healthy and lush lawn.

When is the Best Time to Plant Grass Seed in Nebraska?

Spring Planting

The ideal time to plant grass seed in Nebraska is in early spring as it coincides with the start of the growing season. 

Spring gives the seedlings enough time to develop before the hot summer months. The ground is warmer and soil moisture is abundant. 

Early spring rainfall also makes it easy for the grass seed to germinate. 

Planting in early spring from March through April, allows enough time for seed germination before summer arrives.

Fall Planting

Alternatively, you may plant grass seed in the fall, when the temperature is still warm, yet not hot. 

Planting cool-season grass seed in the fall from late August through early September is an excellent time to establish a new lawn or overseed an existing one. 

The seed is planted after the heat of summer has passed, providing ideal germination conditions for cool-season grasses. 

Moreover, the cool temperature and abundant moisture in the fall provide an excellent environment for seedling development.

Factors to Consider

The ideal time to plant grass seed depends on a variety of factors, including location, soil moisture, and temperature. 

Be sure to plant grass seed when the weather is ideal for seed germination and avoid planting in extreme temperatures, which can harm the young seedlings. 

Ideal germination temperatures range between 60°F to 75°F (15°C to 24°C). When planting in the fall, keep in mind that you should plant the seed before the first frost happens.

Preparing Your Lawn for Grass Seed

Soil Preparation

Soil preparation is critical for the health of your new grass. First, make sure to clean the area of any debris and weeds. 

Use a weed killer, preferably a non-discriminating herbicide, before leveling the soil. Rake the topsoil flat and then spread the grass seed. 

Ideally, the soil should have a PH between 6.0 and 7.5. If it doesn’t, use a lime or sulfur product to adjust the PH accordingly.

Seed to Germinate

After preparing the soil, you will need to ensure that the seed has everything it needs to germinate such as water, sunlight, warmth, and oxygen. 

Grass seed requires proper moisture to germinate and should be watered frequently. If the soil dries out, the seedlings won’t survive. 

Watering for short periods, frequently, is better than watering once a week for an extended period of time.

Seed Bed Preparation

When planting grass seed in Nebraska, you will need to create the correct seed bed. Aeration, which is poking small holes in your soil, helps the grass roots penetrate deeper and take in more oxygen. 

Spread the seed over the prepared soil using a seed spreader, and then rake the seed into the soil. Use a roller to ensure the seedbed is level. 

A flat surface heightens the chances of soil erosion due to rainwater.

Seed Rate and Spacing

The amount of seed to use is important. Too much grass seed can create a patchy lawn while too little seed will not germinate evenly. 

The ideal amount of seed to use is one to two pounds of seed per 1,000 square feet. Overcrowding can cause poor growth and disease. 

Grass seed spacing is critical, as the seed needs space and light to germinate properly.


Overseeding is an excellent way to repair a patchy lawn or to create a new lawn on an old spot. 

Combining the new seed with the existing grass will not only result in a fuller and thicker lawn but will also help fill in the bare areas. 

Overseeding your lawn should be done in the early spring or fall for the best results.

Aeration and Fertilization

Aeration helps the grass roots to breathe. This is beneficial to your grass, particularly if you have heavy soil or there is constant traffic on the lawn. 

Fertilizing is also critical if you want a healthy lawn. Typically, this is done in the spring and fall. You can use organic or inorganic fertilizer for optimal results.

Caring for Your Lawn After Planting Grass Seed


After planting the seed, water your lawn regularly to ensure that your grass develops healthy roots that can absorb more water and nutrients. 

You must keep the soil moist for the next two weeks, avoid overwatering, which may wash away the seeds.


You can mow your lawn once it reaches about 3-4 inches in height, this usually takes around a week. Use a sharp mower and avoid harsh, abrupt turns that can damage the new roots. 

When cutting your lawn, never take off more than one-third of the blade length.

Weed Control

Weeds can kill newly established grass. Crabgrass and broadleaf weed killers can help eradicate weeds before planting the grass seed. 

Always use it with caution, as it can harm the new grasses. Once the new grass is established, apply weed killers that are safe for it.
