Topdressing is the task of applying a mixture of sand and topsoil to the surface of a lawn. The renovation process is based on enhancing the Integrity of the existing grass, so as to cause as little damage as possible.
You will need to spread the topsoil in an even layer over the surface of the lawn. If need be you can fill in any depressions in the surface and mix in some extra seed.
Topdressing a lawn is a process of adding a thin layer of material over the grass. Typically 1 – 2cm of compost is spread across the lawn with shovels, in a throwing action; it can actually be good fun. The dressing can then be worked into the thatch layer by raking, washed in with sprinklers or be allowed to settled on its own.
It is fairly labour intensive and maybe that is way many lawns do without it. There are motorised machines available, but they can be costly especially for a machine that is rarely used. The possibility to hire one could be the answer, ask your local hardware if there is a place you can rent one.
Consumers have become sensitive to the issues surrounding chemical lawn care; they are beginning to learn the advantages of requesting the service from lawn care pros.
Topdressing benefits are so numerous; it’s hard to understand why it is not the foundation for every lawn care program. As a soil amendment, topdressing can improve soil biology by adding organic matter and the beneficial micro orgasms found in compost. Soil structure and drainage can be modified by topdressing with sand or other corrective materials.
Topdressing regularly can smooth out bumps caused by worm castings and encourages a dense, lush lawn. Topdressing reduces lawn stresses, helps keep thatch under control and acts as a long term fertiliser. Adding organic matter to a lawn with topdressing is arguably the most beneficial cultural practice that the science of lawn care has to offer.
Topdressing can vary in quality; high quality should be dark and rich and contain a a variety or organic materials with few fillers such as sawdust or loam. In some cases, it is blended with soil or sand to make it more affordable and easier to spread. Compost should be made from the appropriate ratios of wet and dry materials and should be fully “cooked” in other words highly decomposed.
Sand is added to the dressing for lawns with heavy, clay soil or drainage problems. This is usually applied after aerating; the sand fills the holes and over time can alter the structure of the soil for better drainage and healthier grass.
Traditionally topdressing is spread over the lawn using a shovel, using a throwing motion. Fling the compost with a smooth swinging motion aimed at spreading the materials as evenly as possible to a depth of 1- 2cm. Follow this by lightly raking the lawn to ensure that the topdressing is evenly distributed. Watering immediately will help settle the material and keep it in place.
It is a good idea to perform topdressing in conjunction with other cultural practices, such as aerating, de-thatching and overseeding. Topdressing after aerating and overseeding is the ideal trio of lawn care practices, sure to create a healthier lawn.
