Ensuring proper runoff and drainage is an essential step in maintaining a healthy lawn. If rainwater accumulates in your lawn rather than draining away from it, it can lead to numerous problems later down the road. To learn more about soil erosion and how to prevent it, keep reading.
What Causes Soil Erosion?
Soil erosion is typically caused by excessive rainfall or irrigation in areas of a lawn with poor runoff.
Water is essential for all living organisms, and grass is no exception. Without rain, your lawn would turn brown and die, regardless of the variety.
But too much water can be equally as bad. When water pools up on a law, it washes away the topsoil, which is where a significant concentration of beneficial nutrients and microorganisms are located.
Furthermore, soil erosion can cause problems to your actual home. Allowing water to pool up along the perimeter of your home can cause increased moisture inside your home, especially the basement or crawl space.
And as most homeowners already know, moisture leads to mold – something that you definitely want to keep out of your home.
How to Prevent Soil Erosion
Thankfully, there are several steps you can take to protect your lawn from soil erosion, beginning with maintaining healthy grass.
If your lawn’s current grass is thin and weak, it’s more likely to get washed away during a rainstorm. However, if you choose a hearty grass, it will serve as a natural barrier, protecting your lawn and the underlying soil from erosion.
You can also reduce the risk of soil erosion by ensuring your soil is compacted. If you recently added a new layer of soil, make sure it’s compacted enough to withstand small streams of water.
Contrary to what some people believe, you don’t need any special machine or equipment to perform this task. As explained in this SFGate article, you can compact your lawn’s soil using a water hose.
Of course, grading a lawn is essential if it doesn’t have proper runoff.
What is proper runoff? Basically, your lawn should be sloped down and away from your home.
If your lawn slopes towards your home, water will accumulate at the base where some of the moisture subsequently seeps into your home’s crawlspace or basement.
Baffles and barriers can also be used to prevent soil erosion. Once installed, they obstruct the flow of water, diverting it downhill towards the appropriate area.
Most baffles and barriers are made of, or at least contain, stone or wood. They are best used for small slopes.
