By topdressing your lawn with about 1/4 an inch of compost, sand, or other material, you’ll be amending and improving the quality of the soil in your lawn. It can also smooth out bumps and encourage the grass to grow thick and lush. But what’s the best top dressing for lawns and what should you consider when choosing the right material? Show The best top dressing for lawns is compost because it is rich in nutrients and can help improve the soil structure in your lawn. Applying compost also reduces the fertilizer and water needs of a lawn since it improves water retention and may contain both micro and macro-nutrients required by grass. What makes a good lawn top dressing?A good top dressing material for lawns should have a mix of sand, peat, and loam soil. These components are the closest to soil’s natural composition and can be easily incorporated into your soil. However, the nature of the soil in your yard may require a specific type of top dressing. Compost, sand, and topsoil are the best topdressing materials for lawns. Sand, for example, is a great topdressing material for a bumpy lawn. It smoothens and levels the ground while improving the soil’s drainage, which gives a big boost to the growth of grass. On the other hand, peat (such as sphagnum or finely sieved sedge peat) acidifies the soil and prevents worm infestation. High-quality loam soil encourages the growth of grass when used as a top dressing material for slow-growing grass. As we’ve already established, a good top dressing for your lawn should have sand, topsoil that’s similar to your lawn’s existing soil, or high-quality compost. A custom blend mix of sand, compost, and soil can also make a great top dressing to use. Each of these materials has different benefits and may be suitable for different needs. Here are the 4 best top dressings for lawns: 1. SandThe application of sand as a topdressing material is widespread, especially in places like golf courses. Sand has excellent benefits, especially if it has no lime since lime can damage grass by altering the soil’s pH. Sand should be applied as a light layer of 1/8″ – 3/8″ to improve the quality of the turf and reduce the severity of some turf infections such as anthracnose. Also, ensure the texture of the sand you use is as close in composition to the native soil on your lawn. Avoid using fine sand over coarse-textured soil. Here are the benefits of using sand as topdressing for your lawn:
Disadvantages of using sand for top dressing There are a few disadvantages of using sand as a top dressing. These include:
Suitability of sand as topdressing material Overall, sand is a great top dressing when you want to improve the drainage of your lawn. Adding a thin layer of sand to your turf periodically means that water drains freely to the roots, promoting the healthy growth of grass. Sand is also suitable because of its good integration into your lawn. It is not easily visible and will promote a clean, smooth finish to your lawn’s appearance but also help supports grass varieties that grow in sandy soils. 2. Compost
Compost is organic material that is added to soil to make it healthier and more productive. It is by far the best for use as a top dressing because it moves down through grass better than most other types of top dressing. You do not have to buy ready-made compost as it can be made at home using food scraps and waste gathered from your yard such as leaves from trees. Excellent compost can be made from organic matter such as grass clippings, eggshells, fruits and vegetables that have gone bad, and the green matter that is moist. All these are rich in nitrogen, which is great for making your grass turn greener. Benefits of using compost for top dressing
Disadvantages of using compost for top dressing Compost manure can lack nutrients or get easily contaminated. You would have to do a test to ascertain that compost has all the required nutrients. Overall, compost is a great top dressing for lawns that require a boost in nutrients. It is mostly organic and can improve the texture and quality of the soil on your lawn. There are no long-term effects of adding compost to your lawn on a regular basis. It is, however, important to ensure the compost you add to your lawn is free of pests and contaminants of any kind. 3. TopsoilTopsoil is the uppermost 5-10 inches of soil. It is rich in organic matter and microorganisms that are beneficial to plants. To use topsoil, ensure that it is similar to the existing soil structure. Topsoil is not heavy and spreads easily over grass. Benefits of using topsoil as top dressing
Disadvantages of topsoil as top dressing
It is recommended to mix topsoil with organic matter or compost to boost its nutrients. However, it is light in texture and has good drainage properties that are great for top dressing for your lawn. 4. Blended mixThe use of a blended mix of topsoil, high-quality compost, and sand would work best. You can purchase these mixes ready-made from stores, or you can choose to do the preparation and mixing yourself. You would be incorporating all the advantages of individual top dressing materials and reducing disadvantages. Compost, for example, would enrich the topsoil and sand. This blended mix is considered the better option compared to using individual components. Is top dressing the same as topsoil?Top dressing is different from topsoil. Topsoil refers to the topmost layer of soil (usually 5-10 inches) while top dressing is the organic material, sand, topsoil itself, or even a blend of these materials that’s spread over grass or gardens. Top dressing helps level the ground as well as enrich it with nutrients. Topsoil does not necessarily contain any nutrients unless they have been incorporated by the use of fertilizers. It can be used individually or added to compost and sand to get the best top dressing product. The final outcome then becomes perfect for use as a top dressing for lawns. References
