How To Overseed or Reseed Your Lawn In 10 Easy Steps

In order to avoid having a lawn that looks like a barren desert, you need to know how to reseed your lawn. By following these simple steps, you can create a beautiful and healthy lawn that will last for years.

Seeding a lawn is the process of planting new grass seed in an area where the grass is thin or missing. There are two ways to do this: overseeding and reseeding. Overseeding is the best way to fill in small patches of thin or balding grass. Reseeding is done when you want to replace your lawn’s grass completely.

How To Overseed or Reseed Your Lawn In 10 Easy Steps

If you’re noticing your lawn is looking a little thin or the color isn’t as bright as it used to be, you may need to overseed or reseed it. Overseeding or reseeding your lawn is a great way to improve your yard’s overall health and appearance. By planting new grass seed, you can fill in any bald spots or thin areas and help your lawn become thicker and more resistant to weeds and pests.

Step 1: Making a plan

Making a plan helps you focus your efforts on overseeding or reseeding the lawn. A plan provides direction and guidance on what steps you need to take to achieve your goal. You should consider different things before starting, like tools, materials, cost, and labor. No matter which process you choose, there are a few tools and materials you’ll need to overseed or reseed:

Tools list

  • Lawn Aerator: This tool creates holes in the soil, allowing air, water, and nutrients to reach the grass roots; This makes it easier for new grass seeds to take root and grow.
  • Dethatcher: This tool removes dead grass, thatch, and other debris from the lawn, which can help improve the soil condition and make it easier for new grass seeds to germinate.
  • Seed Spreader: This tool evenly distributes grass seed across the lawn. There are different types of seed spreaders available, including hand-held models and walk-behind models.
  • Lawn Roller: This tool presses the grass seed into the soil, creating good soil-to-seed contact; This helps ensure the seed gets enough moisture and nutrients to germinate and grow.
  • Rake: This tool is used to prepare the soil before seeding by removing large clumps of dirt or debris and smoothing the surface.
  • Watering Can or Hose: Once the seed has been sown, keeping the soil moist is essential until the grass has established itself. You can use a watering can or hose to water the seeds regularly.
  • Fertilizer Spreader: After seeding, you may want to fertilize your lawn to help the new grass grow strong and healthy. You can use it to distribute the appropriate amount of fertilizer evenly across the yard. Also, you can use a compost spreader as an eco-friendly option to fertilize your lawn.

Step 2: Choose the best time

Overseeding is often done in the fall, when the weather is cool and the days are shorter. The new seed will germinate and grow slowly over the winter, so that by the time spring arrives, your lawn will be thicker and fuller.

The best time to overseed a lawn is typically in the fall, about 4-6 weeks before the first expected frost. This allows the new grass seed to germinate and establish itself before winter sets in. In addition, temperatures are cooler in the fall which helps prevent the soil from drying out too quickly while the new seedlings develop.

In some regions, spring can also be a good time to overseed a lawn. However, it’s important to wait until after the last frost date in your area to avoid any damage to the new grass seedlings.

The best time to reseed a lawn depends on several factors, such as the type of grass you have, the climate in your area, and your schedule. In general, the best time to reseed a cool-season grass like Kentucky bluegrass or fescue is in the early fall, when temperatures start to cool down but before the first frost. This allows the grass to establish strong roots before winter sets in.

If you live in a warmer climate with warm-season grasses like Bermuda or Zoysia, the best time to reseed is in late spring or early summer, when temperatures are warm enough for the seeds to germinate and grow quickly.

Step 3: Prepare the area to overseed or reseed your lawn

There are a few key things you can do in preparation for overseeding or reseeding your lawn. Once you’ve prepared the area, it’s time to choose your seed.

  • Remove any debris from the area, including leaves, branches, and stones.
  • Rake the area to loosen the soil and create a smooth surface.
  • Apply a layer of compost or manure to the area and rake it in.
  • If you’re overseeding, spread the seed evenly over the area and rake it in. Dig up the entire lawn and remove any old grass or weeds if you’re reseeding. Sprinkle the new seed over the place and rake it in well.
  • Water the area well until the soil is completely moistened.
  • Keep the area wet until the new grass has grown in completely—usually about two weeks.

Step 4: Solve existing lawn problems

Solve existing lawn problems

There are many common lawn problems that can occur, such as weeds, bare patches, brown spots, pests, poor drainage, and compacted soil. Here are some tips on how to fix these issues:

  • Weeds: Weeds can be a significant problem for lawns, especially if they grow unchecked. Common weeds include dandelions, clover, crabgrass, and thistle. To remove weeds, manually pull them out by hand or use an herbicide. If using an herbicide, make sure to read the label instructions carefully.
  • Bare patches: Bare patches in the lawn can be caused by various factors, including heavy foot traffic, insect damage, and disease. If the grass is thin or patchy, it may be due to a lack of nutrients in the soil. In this case, you can add some organic matter or fertilizer to help improve the quality of the soil. The best way to fix bare spots is to reseed the area. Prepare the soil properly before seeding, and regularly water the area until the grass grows back.
  • Brown spots: Brown spots in the lawn can be caused by several factors, including lack of water, heat stress, and fungal disease. To fix brown patches, find the underlying cause and address it. For example, if a lack of water causes the brown patch, water the area more frequently.
  • Insects: Various insects can damage lawns, including grubs, chinch bugs, and armyworms. To eliminate them, use an insecticide specifically designed for lawn pests. Follow the instructions carefully and apply the insecticide when the pests are most active.
  • Fungal diseases: Fungal diseases such as powdery mildew and the brown patch can cause damage to lawns. You have to take some steps to control fungus in your lawn, like Mow your lawn regularly and at the correct height, water your lawn correctly, improve soil drainage by aerating your lawn, use an appropriate fungicide for the type of fungus if necessary, and follow the instructions carefully.
  • Poor drainage: Lawns that don’t drain well can develop standing water areas, leading to root rot and other problems. Improve soil drainage by aerating your lawn and removing any thatch buildup.
  • Compacted soil: Soil that has become compacted can make it difficult for grass roots to penetrate, leading to weak and thin grass growth. You can solve compacted soil in your lawn by taking some steps, like limiting foot traffic on the lawn by creating designated paths or walkways, using a core aerator to remove small plugs of soil, topdressing with compost or sand, and watering your lawn correctly.

Step 5: Select a quality grass seed product

When it comes time to overseed or reseed your lawn, you want to select a quality grass seed product. The best time to do this is in the early fall, before the first frost.

In order to make sure your lawn looks great all year, it’s essential to choose a high-quality seed mix that will germinate quickly and fill in any bald spots. 

There are many different types of grass seed available on the market, so be sure to do your research before purchasing. Some popular varieties include Kentucky bluegrass, ryegrass, and fescue. 

Always use grasses suited for your climate and high-quality grass seed. If you’re unsure which type of grass is best for your climate and soil type, consult with a local garden center or landscaper.

Step -6: Spread your grass seed

You need to remember a few key things when spreading grass seed to overseed or reseed your lawn:

  • Make sure you are using the correct type of seed for your climate and the specific needs of your lawn.
  • Be sure to water the seed properly for it to germinate and take root.
  • Give the new grass enough time to grow before mowing it.
Best seed spreader

Apply seed at the stated overseeding rates using the appropriate lawn spreader. To treat large lawns, use drop or broadcast spreaders. Small patches can be seeded by hand. Work in calm air to ensure seed distribution.

Step 7: Fertilize your new grass

Fertilize your new grass

The best time to fertilize overseeded areas of your lawn is after the new seedlings have germinated and started to grow. A light fertilizer application will help the new seedlings get off to a strong start. Choose a fertilizer that is high in nitrogen and low in phosphorus. This type of fertilizer will help the grass to grow thick and healthy. Be sure to water the lawn well after you apply the fertilizer. Stay away from weed and feed products. Seed germination is inhibited by pre-emergent herbicides.

Step -8: Water your new grass

Water your new grass

A healthy lawn is a beautiful thing. Not only does it make your home look good, but a well-maintained lawn is also great for the environment. One of the most critical aspects of lawn care is watering. If you want new grass to grow, you need to water it regularly.

Watering schedule for new grass seed depends on various factors such as the type of grass, soil type, weather conditions, and the location. However, here are some general guidelines that you can follow:

  • Generally speaking, though, you should water your lawn at least once a week. However, you may need to water it twice a week or more in hot weather.
  • If you’re not sure how much water your lawn needs, there are several ways to test it. One easy way is to stick a screwdriver into the ground near one of your plants.
  • Overseeded lawns need regular watering. Water seed and soil lightly twice daily for the first four days, then more strongly every other day for five days, then as is necessary to prevent wilting. This promotes strong roots.
  • Keep the soil moist but not saturated. Overwatering can cause the grass seeds to wash away or lead to fungal growth.
  • Water for short periods of time, around 5-10 minutes per session, until the grass reaches about 1 inch in height.
  • After the grass has reached 1 inch or more in height, water less frequently but more deeply to encourage deep root growth. Once or twice a week should be sufficient, depending on rainfall and temperature.
  • Avoid watering during the hottest part of the day to reduce evaporation.

Step -9: Regular maintenance 

Regular maintenance 

Congratulations on your new lawn! Maintain a healthy lawn with regular watering, proper mowing, and proactive overseeding. A weekday lawn care routine can keep your weekends free and your grass green.

One of the keys to keeping your lawn looking its best is to develop a regular maintenance schedule and stick to it. This means mowing regularly, watering when needed, and addressing any problems as they arise.

Mowing Schedule for a new lawn

Here is a mowing schedule to help you keep it healthy and looking great:

  1. Week 1: Let the grass grow about 3-4 inches before the first mow.
  2. Week 2-3: Mow the grass to a 2-3 inches height.
  3. Week 4-5: Mow the grass to a height of 1.5-2 inches.
  4. Week 6 onward: Maintain the grass at a 1-2 inches height by mowing it once a week.

It’s important to cut at most one-third of the blade length in one mowing session, as this can stress the grass and make it more susceptible to disease and pests. Also, keep your mower blade sharp, as a dull blade can tear the grass instead of cutting it cleanly.

An excellent way to establish a maintenance routine is to think about your lawn in four quadrants and develop a plan for each one. For example, you might want to mow more often than in the shaded areas in the quadrant that receives the most sunlight.

Watering Schedule for a new lawn

Watering is another essential part of lawn care. You should water deeply but infrequently rather than shallowly and often. This will help encourage deep root growth, which will make your lawn more drought-resistant.

The fertilization schedule for new grass seed depends on the grass you are planting and your region’s climate. In general, it is recommended to fertilize new grass seedlings once they have established a root system and started to grow.

Here is a general fertilization schedule for new grass seeds:

  • Pre-planting: Before planting new grass seed, prepare the soil by removing weeds, rocks, and debris and adding any necessary soil amendments. You can also apply a pre-emergent herbicide to prevent weed growth.
  • Initial fertilization: Once you have planted the grass seed, wait until the grass plants have grown to about 2-3 inches tall before applying the first round of fertilizer. Use a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium (NPK). Apply the fertilizer at a rate of 1 pound per 1,000 square feet.
  • Second fertilization: About 4-6 weeks after the initial fertilization, apply a second round of fertilizer. Use a fertilizer with a higher nitrogen content to promote leaf growth. Apply at a rate of 0.5 pounds per 1,000 square feet.
  • Third fertilization: Another 4-6 weeks later, apply a third round of fertilizer. Use a fertilizer with lower nitrogen and higher phosphorus and potassium content to encourage root growth. Apply at a rate of 0.5 pounds per 1,000 square feet.

It’s important not to over-fertilize new grass seed, as this can cause the grass to grow too quickly and become weak and susceptible to disease and pests. Also, follow the instructions on the fertilizer package carefully and water the grass thoroughly after each application.

Address any problems in a new lawn

A few common problems can arise in a new lawn, such as patchy growth, weed invasion, and pest infestations. Here are some steps to address these issues:

  • Patchy growth: If areas of your lawn aren’t growing correctly, you may need to reseed or re-sod those areas. Prepare the soil properly before planting, and water frequently to encourage healthy growth.
  • Weed invasion: If weeds have taken over your new lawn, you may need an herbicide to control their growth. Don’t damage your grass while applying the herbicide; follow all instructions carefully.
  • Pest infestations: If you notice pests in your lawn, such as grubs or chinch bugs, you may need to apply a pesticide to control the infestation. Again, follow all instructions carefully and take precautions to protect yourself and any pets or children who may come into contact with the treated area.

With care and attention, you should be able to address any problems that arise and enjoy a healthy, beautiful lawn. If you see any serious problems with your lawn, don’t hesitate to consult your local garden center.

Step -10: Follow proper lawn care schedule

A proper lawn care schedule is important for the health of your grass and the overall appearance of your yard. Depending on the type of grass you have, you will need to mow, water, and fertilize at different times throughout the year. You should also aerate and thatch your lawn on a regular basis. Also, it’s important to clean up dead plants and leaves in the fall to keep diseases from staying in your lawn over the winter. By following a proper lawn care schedule, you can ensure that your grass is healthy and your yard looks its best.

FAQs About Overseeding or Reseeding A Lawn

Q. Is it easy to overseed a lawn?

Overseeding a lawn can be a relatively simple task, but it requires careful planning and attention to detail to ensure it’s done correctly. Here are the general steps involved in overseeding a lawn:

  • Determine the best time for overseeding based on the type of grass you have and your climate. In most cases, early fall or spring is the best time to overseed.
  • Mow your lawn to a shorter length than usual and remove any debris.
  • Use a rake or other tool to loosen up the top layer of soil and create a seedbed for the new grass to grow in.
  • Spread the grass seed evenly over the entire lawn, using a seed spreader to help ensure even distribution.
  • Lightly rake the seed into the soil to ensure good seed-to-soil contact.
  • Water the newly seeded area thoroughly and moisten the soil until the new grass has fully established.
  • Once the new grass grows, gradually reduce the watering frequency and allow the soil to dry out slightly between waterings.

Overall, overseeding a lawn is a simple process, but it does require patience and consistent care to achieve good results. With proper planning and attention, however, you can quickly improve the health and appearance of your lawn through overseeding.

Q. Should you fertilize or overseed first?

If you’re looking to both fertilize and overseed your lawn, it’s generally recommended to perform these tasks at separate times rather than doing them both at once. This makes each task more effective and can lead to better overall results.

First, you should reseed, then a few weeks later, you should put down fertilizer. This allows the newly seeded grass to establish its roots without competition from existing grass or weeds that might benefit more from the fertilizer. Once the new grass has had a chance to grow and develop somewhat, you can then apply fertilizer to help promote healthy growth and development.

It’s important to note that both overseeding and fertilizing should be done at the appropriate time of year for your specific type of grass and climate. Timing is critical for achieving optimal results, so consult with a lawn care professional or research the best practices for your area.

Q. Can you just sprinkle grass seed on lawn?

While it is technically possible to sprinkle grass seed on your lawn, this method is generally not recommended as it can lead to uneven growth and poor results. When you sprinkle grass seed on an existing lawn without any preparation or care, many seeds will likely fail to germinate due to lack of contact with the soil or competition from existing plants.

To effectively overseed a lawn, it’s essential to properly prepare the soil and create a seedbed for the new grass to grow in. This typically involves loosening up the top layer of soil with a rake or other tool, spreading the grass seed evenly over the entire lawn using a seed spreader, and then lightly raking the seed into the soil to ensure good seed-to-soil contact.

By taking these steps and providing proper care and maintenance (such as consistent watering and fertilization), you can help ensure the new grass seed has the best chance of growing and thriving.

Q. How fast does grass grow after overseeding?

The speed at which grass grows after overseeding depends on various factors, including the type of grass seed used, the soil and weather conditions, and the amount of water and nutrients available. In general, you can expect to see some growth within a week or two after overseeding, but it may take several weeks or even months for the new grass to become fully established and reach its full potential. It’s essential to properly care for the newly seeded area by watering regularly, fertilizing as needed, and avoiding heavy foot traffic until the grass has had a chance to strengthen its roots.

Q. Can I put topsoil over grass and reseed it?

Yes, you can put topsoil over an existing grass lawn and reseed it. This technique is known as overseeding and can help improve the quality of your lawn by filling in thin or patchy areas.

Before adding topsoil, it’s essential to mow the grass as short as possible and remove any debris, such as sticks or rocks. Then, spread a layer of topsoil over the lawn using a rake or shovel. Aim for a depth of around 1/4 inch to 1/2 inch of topsoil.

After spreading the topsoil, you can use a lawn roller to pack it down and create a level surface. Then, apply grass seed over the topsoil at approximately 2 to 3 pounds per 1,000 square feet. Be sure to frequently water the newly seeded area for the first few weeks until the grass becomes established.

Q. What is the best grass seed to overseed with?

The best grass seed to use for overseeding depends on your location, climate, and lawn conditions. Different grass species have different requirements for sunlight, soil type, moisture, and temperature.

In general, it’s a good idea to choose a grass seed well-suited to your region and the growing conditions in your area. Here are some commonly recommended grass seed options for overseeding:

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

Perennial ryegrass is a popular choice for overseeding because it germinates quickly and forms a dense, lush lawn. It also has a high tolerance for foot traffic and can withstand heavy use.

Kentucky bluegrass is another popular choice for overseeding. It has a fine texture produces a dark green lawn well-suited to cooler climates. It can take longer to establish than perennial ryegrass but is known for its durability.

Fine fescue is a group of grasses that includes creeping red fescue, chewings fescue, hard fescue, and sheep fescue. These grasses are well-suited to shady areas and can tolerate various soil types.

Tall fescue is a hardy grass that performs well in hot, dry conditions. It has a deep root system that helps it withstand drought and heat stress.

In any case, it’s best to research or consult a local gardening expert to determine the best grass seed for your specific needs.

Q. How much seed do you need to overseed 1 acre?

The amount of grass seed you need to overseed 1 acre will depend on several factors, including the type of grass seed you are using and the recommended seeding rate.

Generally, most grass seeds have a recommended seeding rate of approximately 2-3 pounds per 1,000 square feet for overseeding an existing lawn. Since there are about 43,560 square feet in one acre, you would need between 86-130 pounds of grass seed to overseed 1 acre.

However, it’s important to note that some grass varieties require different seeding rates, so you should always refer to the seed label or consult a local gardening expert to determine the appropriate amount of seed for your specific needs. Additionally, if you use a grass mix instead of a single variety, the recommended seeding rate may differ.

Q. How much topsoil do I need for overseeding?

The amount of topsoil you need for overseeding will depend on the condition of your existing soil and how thickly you want to spread the topsoil.

Generally, a layer of topsoil that is 1/4 inch to 1/2 inch thick should be sufficient for overseeding. To calculate the amount of topsoil needed, you’ll first need to determine the square footage of the area you plan to overseed.

Once you have the square footage, you can use the following formula to estimate the amount of topsoil needed:

Amount of Topsoil (cubic yards) = Square Footage x Depth (in feet) / 27

For example, if you have a lawn that is 1,000 square feet and you want to add a layer of topsoil that is 1/2 inch thick, the calculation would be:

1000 x (1/24) = 41.67 cubic feet of topsoil

To convert cubic feet to cubic yards, divide by 27:

41.67 / 27 = 1.54 cubic yards of topsoil

So in this example, you would need approximately 1.54 cubic yards of topsoil to add a 1/2-inch layer over a 1,000-square-foot lawn.

Q. Can I use garden soil for overseeding?

It is generally not recommended to use garden soil for overseeding your lawn. Garden soil is different from topsoil and may contain unwanted materials such as weed seeds, rocks, and debris that can interfere with the growth of your grass seed. In addition, garden soil may have a different texture and nutrient content than what is needed for healthy grass growth.

Instead of garden soil, it’s best to use high-quality topsoil specifically formulated for lawns and gardens. Look for topsoil rich in organic matter and free of contaminants or additives. You can typically find topsoil at garden centers or landscaping supply stores.

If you choose to use garden soil for overseeding, remove any large rocks or debris and mix the garden soil with existing topsoil to help improve its texture and nutrient content. However, keep in mind that using garden soil may increase the risk of weed growth and other issues that can impact the health of your lawn.

Q. Can I overseed and fertilize the same day?

It is generally not recommended to overseed and fertilize a lawn on the same day, as it can be too stressful for the newly seeded grass. Applying fertilizer can create a barrier that may prevent seed-to-soil contact, which is necessary for successful germination. Additionally, the fertilizer may cause excessive growth in the existing grass, which can compete with the new seedlings for nutrients and moisture.

It is best to wait at least a few weeks after overseeding before applying fertilizer; This will give the new grass time to establish itself and ensure it is not competing with the existing grass for nutrients. Once the new grass has begun to grow and is well-established, you can apply a fertilizer specifically designed for new grass to help it continue to thrive.

Q. How many times should you overseed?

The frequency of overseeding your lawn depends on several factors, such as the type of grass you have, the condition of your soil, and the amount of wear and tear your lawn receives. However, in general, it’s recommended to overseed your lawn every 2-3 years.

Over time, lawns can become thin or patchy due to drought, disease, pests, or heavy foot traffic. Overseeding can help fill in these bare areas and promote healthy grass growth. It also helps bring new seeds that may improve in changing climates or regions.

That being said, if you notice specific areas of your lawn that are particularly thin or patchy, consider overseeding those areas more frequently than every 2-3 years. Additionally, if you have a high-traffic area like a playground or sports field, you may need to overseed more regularly to maintain a healthy, lush lawn.


In conclusion, overseeding or reseeding your lawn is a great way to improve the health and appearance of your lawn. However, it is crucial to choose the right time to do this and use the right type of seed mix. By following these simple steps, you can create a beautiful and healthy lawn that will last for years. Just never forgot the power of overseeding.
