Reseeding a Moss Covered Lawn

To reseed a moss-covered lawn, start by identifying the cause of moss growth and addressing it. Remove as much moss as possible without damaging existing grass. Prepare the soil by adding compost or topsoil and testing the pH. Choose a shade-tolerant grass seed mix and follow instructions for proper seeding. Water regularly, being careful not to overwater. Maintain the lawn by mowing, fertilizing, and watering. Be patient as it can take several months for the new grass to establish itself.

What Causes Moss?

Moss is a common problem in lawns and gardens. It can be caused by a variety of factors, including:

  • Shade: Moss thrives in shady areas where there is little or no direct sunlight. If your lawn is surrounded by trees or buildings that block out the sun, moss may start to grow.

  • Poor Drainage: Moss grows well in damp, poorly drained soil. If your lawn is in a low-lying area or has poor drainage, moss may start to grow.

  • Acidic Soil: Moss prefers acidic soil with a pH of less than 6.0. If your soil is too acidic, moss may start to grow.

  • Compacted Soil: Moss can also grow in soil that is compacted or hard. This can happen if you have heavy foot traffic on your lawn or if your soil is naturally dense.

Moss can easily spread into your lawn through spores in the air. Once it takes hold, it can be difficult to get rid of.

It’s important to note that while moss can be unsightly, it’s not necessarily harmful to your lawn. In fact, some moss in your lawn can help to prevent soil erosion and provide a natural ground cover

However, if you prefer a lush, green lawn, you may want to take steps to remove moss and promote the growth of grass instead.

Understanding Your Lawn

As a homeowner, it’s important to understand your lawn. Here are some things you need to know about your lawn:

Grass Type

The type of grass you have in your lawn plays a significant role in how it grows and how it reacts to different conditions. Some grass types are more tolerant of shade, while others require a lot of sunlight to grow. 

Knowing your grass type will help you determine the best course of action when dealing with a moss-covered lawn.

Soil pH

Soil pH is another essential factor to consider when dealing with a moss-covered lawn. Moss thrives in acidic soil, so if your lawn has a low pH, you’re more likely to have moss growing in it. Testing your soil’s pH will help you determine if you need to adjust it to promote healthy grass growth.


Sunlight is crucial for grass growth. If your lawn doesn’t receive enough sunlight, it can lead to thin, patchy grass, which can create an environment for moss to grow. 

If you have a lot of shaded areas in your lawn, consider planting shade-tolerant grass types or using other methods to promote healthy grass growth.

Compacted Soil

Compacted soil can prevent water and nutrients from reaching the grass’s roots, leading to a weak, unhealthy lawn. Aerating your lawn can help alleviate compacted soil and promote healthy grass growth.

Climate and Region

Climate and region can also play a role in how your lawn grows. Different grass types thrive in different climates, so it’s essential to choose a grass type that’s well-suited for your region. Additionally, if you live in an area with a lot of rainfall, it can create an environment for more moss, to grow.

Identifying and Addressing Problems

When it comes to reseeding a moss-covered lawn, it’s important to first identify and address any underlying problems that may be contributing to the moss growth. Here are some common issues to look out for:

Lack of Sunlight

Moss thrives in areas with little to no sunlight, so if your lawn is heavily shaded, it may be difficult to maintain a healthy lawn. Consider pruning back trees or bushes to allow more sunlight to reach your lawn. Alternatively, you could try planting shade-tolerant grass varieties.

Poor Soil Quality

If your soil lacks the proper nutrients, your grass may struggle to grow and thrive. Conduct a soil test to determine if your soil is nutrient-deficient or too acidic. Once you know what you’re dealing with, you can take steps to amend your soil and improve its overall quality.

Inadequate Drainage

Poor drainage can lead to waterlogged soil, which can create the perfect environment for moss to grow. Make sure your lawn has adequate drainage by ensuring that your soil is properly graded and that water is able to flow away from your lawn.


Overwatering your lawn can also contribute to moss growth. Make sure you’re not watering your lawn too frequently or for too long. Stick to a regular watering schedule and avoid watering your lawn during the hottest part of the day when water is more likely to evaporate.

Weeds and Pests

Weeds and pests can also contribute to a weak, unhealthy lawn. Make sure you’re using the proper weed killer and/or herbicides to keep weeds at bay. Consider using natural pest control methods to avoid harming beneficial insects and animals.

Dead or Weak Grass

If you have dead or weak grass in your lawn, it may be more susceptible to moss growth. Consider removing these areas and reseeding with new grass to help strengthen your lawn.

Moss Removal

Before you can reseed your lawn, you’ll need to get rid of any existing moss. Consider using a moss killer to help remove the moss. Be sure to follow the instructions carefully and avoid using too much, as this can harm your grass.

Reseeding Preparation

Before reseeding, it’s important to ensure that the soil is prepared for optimal grass growth. In my experience, taking the time to properly prepare the lawn before reseeding can make all the difference in the success of the new grass.


One important step in preparation is to aerate the lawn. This can be done using a lawn aerator, which removes small plugs of soil from the ground to improve air and water circulation. 

This is especially important in areas where the soil is compacted or has a high clay content. Aerating the lawn will also help to break up any thatch buildup, which can prevent new grass from growing.


Another step to consider is scarification, which involves using a rake or specialized tool to remove debris and dead grass from the lawn. This process helps to level the lawn and exposes the roots, allowing for better seed-to-soil contact. 

Additionally, scarification can help to improve soil quality by removing any excess thatch and allowing for organic matter to be added to the soil.

Topsoil or Organic Matter

In some cases, it may be necessary to add topsoil or organic matter to the lawn to improve soil quality and provide a better-growing environment for the new grass. This can be done by spreading a layer of topsoil or compost over the lawn and then raking it in to ensure even coverage.

Overall, proper preparation is key to successfully reseeding a moss-covered lawn. Taking the time to aerate, scarify, and improve soil quality will help to kill moss and ensure that the new grass has the best possible chance of thriving.

Choosing the Right Grass Seed

When it comes to choosing the right grass seed for a moss-covered lawn, there are several factors to consider. Here are some of the most important things to keep in mind:


The climate of your region will play a big role in determining which type of grass seed will work best. For example, if you live in a hot and dry area, you’ll want to look for grass seed that is drought-resistant. 

Some good options for these conditions include fine fescue and perennial ryegrass. On the other hand, if you live in a cooler and wetter climate, you may want to consider fescue or Kentucky bluegrass.

Soil Type

The type of soil in your lawn will also impact which grass seed will thrive. If you have clay soil, for example, you’ll want to look for grass seed that can handle those conditions. One good option for clay soil is tall fescue. If you have sandy soil, on the other hand, you may want to consider zoysia grass seeds.

Sun Exposure

The amount of sun exposure your lawn gets will also be a key factor. If you have a lot of shade, you’ll want to look for grass seed that can handle those conditions. One good option for shady areas is fine fescue. If your lawn gets a lot of sun, on the other hand, you may want to consider Kentucky bluegrass.

Other Considerations

In addition to these factors, there are a few other things to keep in mind when choosing grass seed. For example, you’ll want to consider the maintenance requirements of each type of grass. 

Some grasses require more watering and mowing than others. You’ll also want to think about the overall look and feel you’re going for. Kentucky bluegrass, for example, is known for its lush and luxurious appearance.

The Reseeding Process

Reseeding a moss-covered lawn can be a daunting task, but with the right tools and techniques, it can be done successfully. Here are the steps I followed to reseed my moss-covered lawn:

  1. Remove the moss: Before reseeding, it’s essential to remove as much moss as possible from the lawn. I used a rake to remove the moss, but for larger lawns, a dethatcher or a power rake can be used.

  2. Test the soil: Once the moss is removed, it’s important to test the soil to determine its pH level and nutrient content. This will help you choose the right grass seed and fertilizer for your lawn. I used a soil testing kit to test my soil.

  3. Prepare the soil: After testing the soil, it’s time to prepare it for reseeding. This involves loosening the soil to create seed-to-soil contact, which is essential for seed germination. I used a garden tiller to loosen the soil and create a smooth surface for seeding.

  4. Choose the right grass seed: Choosing the right grass seed is crucial for successful reseeding. I chose a seed that was suitable for my soil type and growing conditions. It’s important to choose a high-quality seed that is free from weeds and other contaminants.

  5. Seed the lawn: Once the soil is prepared, it’s time to seed the lawn. I used a broadcast spreader to evenly distribute the seed over the lawn. It’s important to follow the manufacturer’s instructions for seeding rates and application methods.

  6. Cover the seed: After seeding, it’s important to cover the seed with a thin layer of soil to protect it from birds and other pests. I used a rake to lightly cover the seed with soil.

  7. Water the lawn: Watering the lawn is essential for seed germination. I watered my lawn daily for the first few weeks after reseeding to keep the soil moist. It’s important not to overwater the lawn, as this can lead to fungal diseases.

  8. Fertilize the lawn: Once the grass seed has germinated, it’s important to fertilize the lawn to promote healthy growth. I used a high-quality fertilizer that was suitable for my soil type and growing conditions.

  9. Maintain the lawn: After reseeding, it’s important to maintain the lawn to ensure healthy growth. This involves regular watering, mowing, and fertilizing. I also used a weed killer to control any weeds that appeared in my lawn.

Overall, reseeding a moss-covered lawn can be a time-consuming process, but with the right tools and techniques, it can be done successfully. Whether you choose to reseed or lay sod to control moss, it’s important to follow the proper steps to ensure a healthy and beautiful lawn.

Post-Reseeding Care

After reseeding your lawn, it is essential to take good care of it to ensure that the new grass seedlings germinate and grow strong. Here are some post-reseeding lawn care tips that I have found useful:

Watering: Water is crucial for new grass seedlings to germinate and grow. After reseeding, I water my lawn daily for the first two weeks, then gradually reduce the frequency to twice a week for the next two weeks, and once a week thereafter. I water my lawn early in the morning or late in the evening to minimize water evaporation.

Fertilizing: Fertilizers are essential for providing nutrients to the new grass seedlings. I use a starter fertilizer that contains high levels of phosphorus, which promotes root growth. I apply the fertilizer two weeks after reseeding and then every six to eight weeks thereafter.

Compost and Mulch: Compost and mulch can help retain moisture and provide nutrients to the soil. I apply a thin layer of compost or mulch over the newly seeded area after reseeding.

Mowing Height: Mowing height is critical for the health of turf grass on your lawn. I wait until the new grass seedlings are at least three inches tall before mowing. I set my mower blade to the highest setting and only remove one-third of the grass blade height at a time.

Pruning: Pruning trees and shrubs around your lawn can help increase sunlight and airflow, which can promote healthy grass growth. I prune my trees and shrubs regularly to prevent them from shading my lawn excessively.

Coverage: It is essential to ensure that the grass seedlings have good coverage and are not too sparse. If the coverage is poor, I overseed the area again and water it lightly.
