For instance, if the existing soil is depleted of nutrients or has a low pH level, adding a thin layer of topsoil can help to replenish the soil and promote healthier grass growth. Nevertheless, it is crucial to apply the topsoil correctly to avoid damaging the existing sod. A thin layer of no more than 1/4 inch of topsoil should be applied, and it should be gently raked into the existing soil to avoid burying the grass blades. It is also important to choose a topsoil that is compatible with the existing soil type and has a similar pH level to avoid any adverse reactions.
Can I put topsoil over sod without damaging my lawn, and what are the potential risks involved?
While it is possible to put topsoil over sod without damaging the lawn, there are potential risks involved that should be considered. One of the primary concerns is that adding too much topsoil can bury the grass blades, causing them to rot and die. Additionally, if the topsoil is not properly integrated into the existing soil, it can create an uneven surface, leading to drainage issues and other problems. It is essential to take a gradual and cautious approach when adding topsoil to an existing lawn to avoid any potential damage.
To minimize the risks, it is recommended to start by aerating the existing lawn to improve soil drainage and reduce soil compaction.
