Identify the Causes of Unevenness

Before you start leveling your garden or lawn, it’s crucial to understand why the surface is uneven. Identifying the root causes of the unevenness can help you choose the most effective leveling method and prevent future issues. Here are some common reasons for uneven terrain:

Natural Settling

Over time, the soil beneath your lawn can settle unevenly, especially after it’s been disturbed by construction or other activities. This natural settling process can create dips and bumps across the landscape.

Water Runoff and Erosion

Improper drainage can lead to erosion, washing away topsoil and creating gullies and dips. This is especially common on sloped properties where water runoff is significant.


Regular foot traffic, children playing, or vehicles driving over the lawn can compact the soil in certain areas more than others, leading to uneven ground. This is often noticeable along pathways or favorite play areas.

Tree Roots

Large tree roots can lift and distort the ground surface as they grow, creating raised areas that can be difficult to mow over or landscape around.

Animal Activities

Burrowing animals like moles, voles, or even larger animals can disturb the soil structure and create unevenness. Their digging and tunneling can leave the surface lumpy and irregular.

Previous Landscaping Work

Sometimes, previous landscaping or gardening work can leave behind uneven surfaces, especially if the soil was not properly settled or if the fill material has decomposed or shifted.

Assessing Your Garden or Lawn

To determine what’s causing the unevenness in your lawn:

Conduct a Visual Inspection: Walk around your lawn and look for patterns of wear, erosion, or unusual growth. Pay attention to areas near downspouts, paths, or under trees.

Check Drainage: During or after a rainstorm, observe how water flows across your property. Note any standing water or areas where runoff is particularly aggressive.

Feel the Surface: Walk over your lawn and feel underfoot for sponginess, which might indicate issues beneath the surface like pest tunnels or root disturbances.

By understanding the specific factors contributing to your lawn’s unevenness, you can tailor your leveling efforts to be more effective and sustainable, preventing similar problems in the future.

Tools and Materials Needed

To level your garden or lawn like a professional, you will need a set of specific tools and materials. Here is a comprehensive list, along with a brief description of each item’s purpose in the leveling process:

  1. Lawn Mower: Before you start leveling, it’s essential to mow your lawn. This helps you see the uneven areas more clearly and makes the process easier by removing long grass that can get in the way.
  2. Garden Rake: A sturdy garden rake is crucial for spreading topdressing materials like soil, sand, and compost. It helps break up clumps and distribute the mix evenly across the lawn.
  3. Shovel or Spade: Used for digging and moving soil, especially when you need to fill in larger depressions or remove excess dirt from bumps.
  4. Wheelbarrow: Essential for transporting soil, compost, sand, and other materials across your garden or lawn.
  5. Lawn Roller: After applying your topdressing, a lawn roller helps press the material down into an even layer, aiding in the settling process and ensuring good contact with the existing soil.
  6. Leveling Rake or Lute: This specialized tool helps in fine-tuning the level of the soil, especially useful for larger lawns or when working with sandy soils.
  7. Topdressing Materials:
  • Topsoil: The base material for most leveling projects, used to fill in low areas.
  • Sand: Helps to improve drainage and maintain a level surface; often mixed with topsoil or compost for better structure.
  • Compost: Enriches the soil and helps with water retention. Compost is mixed with sand and soil to create a nutrient-rich topdressing.
  1. Stakes and String: For severe unevenness, you might need to use stakes and string to mark the desired level across larger areas.
  2. Spirit Level or Laser Level: These tools can be very helpful for ensuring the surface is truly flat, especially useful in larger gardens or for professional landscaping results.

Preparing Your Tools and Materials

Before beginning your leveling project, make sure all your tools are in good working order. Sharpen blades, check handles, and ensure your wheelbarrow and lawn roller are sturdy and functional. Gather all your materials ahead of time to ensure the process goes smoothly, and consider the weather forecast to choose a dry day for the work, as wet conditions can complicate leveling.

With these tools and materials prepared, you’re ready to tackle the leveling process efficiently, ensuring that you not only address the cosmetic appearance of your lawn but also enhance its health and functionality.

Preparation Steps

Before you begin the actual leveling process, it’s important to properly prepare your garden or lawn. This preparation not only facilitates easier leveling but also ensures that the adjustments you make will be more effective and long-lasting. Here are the key steps to prepare your lawn or garden for leveling:

  1. Mow Your Lawn: Start by mowing your lawn to a manageable height. This makes it easier to identify uneven areas and ensures that the topdressing can penetrate the soil surface rather than just sitting on long grass.
  2. Clear the Area: Remove any debris, such as rocks, branches, and large clumps of weeds. This helps prevent any interference with the spreading and settling of your leveling materials.
  3. Dethatch and Aerate if Necessary: If your lawn shows signs of heavy thatch or the soil is very compacted, dethatching and aerating can improve the health of your grass and facilitate better integration of the new topdressing. Dethatching removes a layer of dead turfgrass and other organic matter, while aerating makes small holes in the soil to allow air, water, and nutrients to penetrate the roots.
  4. Identify Major Uneven Areas: Walk around your lawn and flag the areas that need the most work. Use markers or flags to highlight significant dips and mounds. This will help you focus your leveling efforts more effectively.
  5. Water the Lawn Lightly: If the soil is extremely dry, lightly watering the area a day before leveling can make the soil easier to work with. Avoid over-watering as this can make the soil too muddy and difficult to handle.
  6. Measure and Plan: For extensive leveling projects, particularly in large gardens, measure the area and plan where and how much topdressing you will need. This is the time to set up any stakes and string lines to ensure you maintain an even level across the lawn as you work.

By taking the time to thoroughly prepare your garden or lawn, you lay a solid foundation for the leveling process. This not only makes the physical work easier but also ensures the adjustments you make are more likely to last, giving you a healthier, more attractive lawn as a result.

Techniques for Leveling

Once your garden or lawn is prepared, you can start the leveling process. Here are detailed techniques for addressing both minor and major unevenness:

A. For Minor Unevenness

Topdressing Method:

  1. Prepare the Topdressing Mix:
  • Combine topsoil, sand, and compost in a ratio suited to your soil type. For clay soils, increase sand content to improve drainage; for sandy soils, add more compost to enhance moisture retention.
  • Mix thoroughly to ensure a uniform blend.
  1. Apply the Topdressing:
  • Use a shovel or scoop to spread the topdressing over the uneven areas. Start with a thin layer—about ¼ to ½ inch thick.
  • Focus on low spots, but avoid piling too much material at once as this can smother the grass.
  1. Spread and Smooth:
  • Use a garden rake or a leveling rake to spread the topdressing evenly across the surface, working it down into the grass and smoothing out any lumps.
  • For larger areas, a push broom can also be effective in spreading the material.
  1. Water Lightly:
  • After spreading the topdressing, water the area lightly. This helps the material settle and encourages the existing grass to grow through.
  1. Repeat if Necessary:
  • Allow the grass to grow and fill in for a few weeks. If uneven spots still remain, apply additional thin layers of topdressing, following the same process until the desired level is achieved.

B. For Major Unevenness

Reshaping and Filling Method:

  1. Remove the Turf in Uneven Areas:
  • For deep depressions or severe bumps, use a flat spade to cut and roll back the turf. Set it aside to re-lay later.
  1. Add or Remove Soil:
  • For depressions, add new topsoil to fill the area up to the desired level. For bumps, remove excess soil to flatten the area.
  • Use a garden rake or shovel to adjust the soil level, ensuring it matches the surrounding area’s grade.
  1. Re-lay the Turf or Sow New Grass Seed:
  • Once the ground is level, carefully replace the turf you set aside, making sure it’s flush with the surrounding lawn. If the turf is damaged or if you prefer, sow new grass seed instead.
  • Tamp down the turf or soil lightly with your foot or a lawn roller to ensure good contact with the soil beneath and to remove air pockets.
  1. Water and Maintain:
  • Thoroughly water the patched areas, ensuring the new soil settles and the turf or seeds establish well.
  • Keep the area moist until the new grass is established, but avoid over-watering which can cause erosion or wash away seeds.

By using these techniques, you can address both minor and major unevenness in your garden or lawn. Whether you’re smoothing out slight irregularities or correcting larger problem areas, these methods will help you achieve a level, professional-looking outdoor space.

Seeding or Sodding

After leveling your garden or lawn, especially if you’ve made significant changes to the terrain or had to remove sections of turf, you might need to either reseed or lay new sod. Here’s how to decide which option is best for you and how to proceed:

Choosing Between Seeding and Sodding


  • Advantages: Cost-effective, more varieties available, and satisfying to watch grow.
  • Best for: Those who have time to wait for the lawn to establish and who want specific types of grass that thrive in their local climate.


  • Advantages: Instant lawn, less initial watering, fewer weeds, and can be established quickly.
  • Best for: Homeowners who need immediate results and have a higher budget for lawn establishment.

Steps for Seeding New Grass

  1. Choose the Right Seed: Select a grass seed that matches your existing lawn and is suitable for your climate and soil type.
  2. Prepare the Soil: Ensure the newly leveled areas are loose and not compacted. You may need to lightly rake the soil to create a good seedbed.
  3. Sow the Seeds: Spread the seeds evenly using a spreader. For small areas, hand-seeding may be sufficient.
  4. Cover the Seeds: Lightly rake the area again to cover the seeds with a thin layer of soil, or use a roller to press the seeds into the soil.
  5. Watering: Keep the soil consistently moist but not soggy. Frequent light watering is crucial until the seeds germinate and the new grass is well established.
  6. Follow-Up Care: Once the grass reaches mowing height, reduce watering frequency but increase the amount of water to encourage deeper root growth.

Steps for Laying Sod

  1. Prepare the Area: The newly leveled ground should be free of debris and raked smooth. The soil should be slightly moist.
  2. Lay the Sod: Start laying sod along a straight edge, such as a driveway or sidewalk. Butt the edges tightly together without stretching. Stagger the joints in each row like bricks.
  3. Roll the Sod: After laying the sod, use a lawn roller half-filled with water to remove air pockets and ensure good contact between the sod roots and the soil.
  4. Watering: Water thoroughly immediately after installation. Keep the sod well-watered for the first few weeks until roots are established.
  5. First Mowing: Do not mow the new sod until it has rooted, which you can test by gently tugging on it. If it resists, it’s likely taken root.

Post-Leveling Care

After successfully leveling your garden or lawn and either seeding or sodding, it’s essential to provide proper care to ensure the new grass establishes well and your lawn remains level and healthy. Here’s a guide to the crucial steps in post-leveling care:


  1. Consistency is Key: Regular and consistent watering is vital, especially in the first few weeks after leveling, seeding, or sodding. The goal is to keep the soil moist but not waterlogged.
  2. Adjustments Over Time: As the new grass begins to establish, gradually reduce the frequency of watering but increase the amount of water each time. This encourages deeper root growth which is essential for a drought-resistant and robust lawn.
  3. Morning Watering: Try to water early in the morning to reduce evaporation and prevent fungal diseases that can occur with evening watering.


  1. Initial Fertilization: If you haven’t already incorporated a starter fertilizer during the seeding or sodding process, apply a light fertilizer about three to four weeks after planting. This helps promote early root and blade development.
  2. Routine Maintenance: After the establishment phase, implement a regular fertilization schedule based on the specific needs of your grass type and your local climate conditions.

Weed Control

  1. Early Prevention: It’s easier to manage weeds before they become established. If necessary, use a pre-emergent herbicide in the early stages after seeding, but make sure it’s safe for young grass.
  2. Manual Removal: For small lawns or minimal weed problems, hand-pulling weeds is often effective and safe for the new grass.
  3. Post-Emergent Herbicides: If weeds persist, consider using a post-emergent herbicide that is safe for your type of grass. Always follow the manufacturer’s instructions to avoid harming your lawn.

Monitoring and Maintenance

  1. Regular Checks: Regularly inspect your lawn for signs of uneven settling, drainage issues, or other problems. Early detection can prevent small issues from becoming major problems.
  2. Lawn Aeration: Depending on the soil compaction and grass type, aerate your lawn annually or biennially to maintain soil health and allow air, water, and nutrients to penetrate deeper.
  3. Dethatching: Remove thatch if it accumulates more than half an inch, as this can hinder water and nutrient penetration.

By adhering to these post-leveling care steps, you can ensure that your newly leveled lawn grows strong, remains healthy, and continues to enhance the beauty and utility of your outdoor space. Proper care not only maintains the appearance but also extends the lifespan and enjoyment of your lawn.

Common Mistakes to Avoid

Leveling a garden or lawn like a professional requires attention to detail and an understanding of common pitfalls. Avoiding these mistakes can help ensure the success of your lawn leveling project and maintain the health and appearance of your garden. Here are some of the most common mistakes to watch out for:

  1. Ignoring Soil Composition: Not adjusting the soil composition based on your existing soil type can lead to poor drainage and growth issues. Make sure to modify your topdressing mix accordingly (more sand for clay soils, more compost for sandy soils).
  2. Over-watering: While it’s important to keep the soil moist, especially for new seeds or sod, too much water can cause pooling and runoff, which can wash away seeds and newly applied soil. This can lead to uneven settling and potentially reintroduce the unevenness you just corrected.
  3. Applying Too Much Topdressing at Once: Adding a thick layer of topdressing in hopes of a quick fix can suffocate your grass, leading to brown patches and grass death. It’s better to apply thin layers gradually, allowing the grass to grow through between applications.
  4. Skipping the Prep Work: Failing to properly prepare the area by removing debris, dethatching, and aerating (if necessary) can hinder the effectiveness of your leveling efforts. Proper preparation ensures the topdressing integrates well with the existing soil and provides a good base for grass growth.
  5. Using the Wrong Materials: Not all materials are suitable for all situations. Using pure sand on a lawn that already struggles with drainage won’t help, and heavy clay might only worsen the situation for a sandy soil lawn. Understanding and choosing the right materials for your specific conditions is crucial.
  6. Ignoring Long-term Maintenance: Once leveling is done, some might neglect ongoing maintenance like fertilization, regular mowing, and aeration. Continuous care is crucial to keep the lawn healthy and prevent future unevenness.
  7. Uneven Application of Seed or Sod: When seeding, it’s important to spread the seeds evenly to avoid patchy areas. With sod, ensuring that seams are tightly fitted and the sod is firmly pressed into the soil can prevent bumps and gaps.
  8. Rushing the Process: Trying to speed through the project can result in overlooked details and mistakes. Take your time to measure, prepare, and apply materials carefully to achieve the best results.

By being mindful of these common errors and approaching each step of the leveling process with care and precision, you can avoid setbacks and achieve a beautifully leveled lawn that enhances your outdoor living space.
