One of the most important steps in learning how to grow grass is knowing when to plant new grass seed. Ultimately, it will depend on the weather in your area and the type of grass you want to grow. The best times to plant seed grass are usually spring and early fall when the soil is warm and there's plenty of moisture.

What Tools and Materials Do I Need for Planting Grass?

The best way to plant grass seed is with the right tools. Here's what you need for lawn seeding.

    Key Considerations Before Planting Grass Seed

    Reseeding bare or thinning law spots may not be effective if you don't identify the root cause. Without understanding the underlying issue, you may need to reseed multiple times. Possible causes include:

    • Inadequate watering
    • Not enough sunlight
    • Cutting the grass too short
    • Soil nutrient deficiencies or pH problems
    • Grass disease
    • Pet urine
    • Excessive thatch buildup
    • High levels of foot traffic
    • Pests
    • Intrusive tree roots

    Once you've determined the root cause, you can take measures to address the issues damaging your lawn. For example, if inadequate watering is the problem, adjusting your irrigation schedule or investing in a sprinkler system may help. If it's a lack of sunlight, consider pruning nearby trees or choose grass types that grow better in the shade. Correcting soil nutrient deficiencies, combating disease, and deterring pests may require special fertilizers, fungicides, and pest management strategies. Other problems may need expert advice to solve.

    How Do You Plant Grass Seed?

    Once you have all your tools and have fixed the root cause of thinning lawn spots, it's time to start planting seeds. Here's how to plant grass seed and nurture your lawn so it stays healthy and vibrant.

    Choose the Right Grass Seed for Your Region

    The first step for planting grass seed is choosing the right type of grass for your area. Different grasses thrive in different seasons. Here's a look at what works best in each season.


    The best time to plant cool-season grasses is during the fall. This lets them create strong root systems before the hot summer. Cool-season grasses include:

    • Kentucky bluegrass
    • Perennial ryegrass
    • Tall fescue
    • Fine fescue
    • Creeping fescue
    • Bentgrass


    Warm-season grasses, on the other hand, should be planted in the late spring. These grasses grow better in the warm summer months. Warm-season grasses include:

    • Bermudagrass
    • Centipedegrass
    • Bahiagrass
    • Zoysiagrass
    • Buffalo grass

    Warm & Cool Grass
    for the Transition Zone

    If you're in a transition zone, which has a mix of warm- and cool-season conditions, you should choose grasses that adapt better to changing climates, such as:

    • Tall fescue
    • Perennial ryegrass
    • Kentucky bluegrass
    • Bermudagrass
    • Zoysiagrass


    Pulling weeds from grass

    Pull Out Weeds

    Lawn seeding is most effective when you start with a clean slate. Before seeding, remove weeds to give your new grass a fighting chance. Here are some options for weed removal.

    • Manual removal: Hand-pull weeds or use a weeder to get rid of them. Make sure to remove the entire weed, including the roots.
    • Chemical removal: Use herbicides to eliminate weeds. Follow the product instructions carefully and observe safety precautions.
    • Mechanical removal: For larger areas or those with a lot of weeds, you can use a lawn dethatcher or sod cutter.



    Prepare & Break up Your Soil

    How to use grass seed effectively involves preparing your soil to create the perfect environment for germination. To do this:

    • Remove any rocks, sticks, or debris from the area where you plan to seed.
    • Mow any existing grass as short as possible to help the seed reach the soil.
    • Use an aerator to create holes in the ground for water, air, and nutrients to enter the soil.
    • Rake the soil to create a level surface area for seeding.
    • Test the soil to determine the pH and nutrient levels and adjust it based on the results.

    Add Compost to the Soil

    The best way to grow grass is to add compost to your soil. Compost is rich in essential nutrients and promotes beneficial microbial activity in the soil, both of which help grass grow. It also improves soil structure to help with water retention and drainage.

    To add compost, first spread a layer of compost over the prepared soil. Then, use a rake to mix the compost into the soil thoroughly. Try to evenly distribute the compost to ensure nutrient consistency throughout your grass.



    Create a Seed & Potting Soil Mix

    Mixing your seeds with potting soil is one of our top tips for how to grow grass from seed effectively. Potting mix provides an ideal environment for germination and early growth. Combining high-quality seeds with potting soil ensures the seeds have the necessary nutrients, moisture retention, and structural support for strong root development. This mix also helps you more evenly distribute the seeds across your lawn.

    Plant the New Grass Seed

    The next step for seeding a lawn is to plant the seeds. Here's how to spread grass seed evenly to ensure proper growth.

    • Use a seed spreader or your hand to evenly distribute the seed and potting soil mix across the area.
    • When using a seed spreader, slightly overlap the previous pass to ensure full coverage.
    • Follow the recommended seeding rate for the grass you chose.
    • After seeding, use a rake to lightly press the seeds into the soil. This improves seed-to-soil contact and promotes germination.



    Cover and Protect the Grass Seed

    One of the best ways to grow grass is to keep it safe from harsh weather, birds, and other potential threats during the germination phase. To do this, spread a thin layer of mulch over the seeded areas, as this helps retain moisture and prevents birds from eating the seeds. We also recommend using our Grass Fast® Germination Aid, which allows your seeds to stay in place to germinate quickly. Forget the paper-thin garden fabric covers that rip easily — our fabric cover provides erosion control in sloped areas and keeps your seed safe from birds and other animals.


    Gently watering new grass seed

    Water the Grass Seed

    Proper watering is crucial for your seeds to flourish. Here are some watering tips to ensure your grass seeds thrive:

    • Lightly water the seeded area frequently to prevent the soil from drying out.
    • Avoid overwatering because it can cause seed washout and other issues.
    • Try to water early in the morning as it allows the grass to dry before evening, reducing the risk of disease.
    • Use a soil moisture meter to track moisture levels in the soil and adjust your watering accordingly.
    • After germination, transition to deeper, less frequent watering to encourage deeper root growth.



    Keep Your Lawn in Good Condition

    Maintaining your lawn post-planting is equally important as learning how to grow grass. To maintain a healthy lawn:

    • Regularly mow it and feed it with the appropriate fertilizer.
    • Use herbicides to prevent weed growth and address pest problems quickly to avoid damage.
    • Maintain proper watering practices and make sure your lawn receives adequate moisture.
