Lawn soil, often referred to as topsoil when used for lawns, is best applied as a topdressing to improve soil quality and promote healthy grass growth. Here's how to use it effectively:
1. Determine Your Needs:
- Leveling Uneven Areas: Lawn soil can fill in low spots or divots, creating a smoother surface.
- Improving Soil Quality: If your existing soil is poor (e.g., compacted clay or sandy soil), a layer of lawn soil can improve drainage, aeration, and nutrient retention.
- Overseeding: Topdressing with lawn soil after overseeding helps protect the new seeds and provides them with essential nutrients for germination.
2. Preparation is Key:
- Mow the Lawn: Cut the grass short before applying lawn soil.
- Dethatch (if needed): If you have a thick layer of thatch (dead grass and debris), dethatch the lawn to allow the soil to reach the ground.
- Aerate (if needed): Aerating helps loosen compacted soil, improving drainage and root growth.
3. Application Techniques:
- The "Fling" Method: The reference suggests using a shovel to "fling" small amounts of lawn soil across the surface. This involves scooping a small amount of material and using a sweeping motion, similar to hitting a hockey puck, to spread it evenly. This works well for smaller areas.
- Wheelbarrow and Shovel Method: For larger areas, use a wheelbarrow to transport the soil. Shovel small piles of soil across the lawn.
- Spreader (for some topsoil types): Some types of topsoil or compost mixes are fine enough to be applied using a fertilizer spreader. Check the product instructions.
4. Spreading Evenly:
- Small Areas at a Time: Work in small sections (a few square feet).
- Thin Layers: Apply a thin layer, typically ⅛ to ½ inch. Avoid burying the existing grass.
- Rake it In: Use a rake to distribute the soil evenly and work it into the existing grass. This will help fill in gaps and ensure good contact between the soil and grass blades.
5. Watering:
- Water Thoroughly: After applying the lawn soil, water the lawn thoroughly. This will help settle the soil and provide moisture for grass growth.
Example Scenario:
Let's say you have a small patch of lawn that is uneven. You can use lawn soil to level it. First, mow the area. Then, using a shovel, carefully spread a thin layer (¼ inch) of lawn soil over the low spots. Rake the soil to smooth it out and blend it with the existing grass. Finally, water the area well.
Important Considerations:
- Type of Soil: Choose a lawn soil that is appropriate for your existing soil type and the type of grass you have.
- Quantity: Calculate the amount of lawn soil needed based on the area you're covering and the desired depth.
- Weather: Avoid applying lawn soil during heavy rain or extreme heat.
