How to Use Mulch to Control Water Runoff
Mulch is a great landscaping tool for many reasons. It comes in a variety of colors to match any garden theme, and fresh mulch gives you a sweet, outdoorsy aroma. More importantly, mulch helps prevent erosion.
Mulch protects your soil from the impact of wind and rain. It also helps retain moisture, so the ground doesn’t dry out as quickly, which keeps your plants hydrated. On the contrary, mulch can also help reduce the retention of too much water, causing additional problems in your landscape.
Mulch Weight for Erosion Control
If your yard gets a lot of shade and is relatively flat, your soil doesn’t need as much protection as if it were exposed to more elements. In cases like this, you can use something lightweight to improve the aesthetics of your landscape.
When your yard is on a steep slope, is in a wind tunnel, or is exposed to the sun and the rain without cover, you need something heavy duty. You have to completely cover your soil to protect it and provide adequate erosion control for your plants.
Using Mulch to Prevent Ponding
Ponding occurs in your yard when you have areas with improper slopes or very dense soil. Water can’t drain and ends up creating mud or standing water. Landscape professionals can install drains to correct the problem, or you can fix it yourself with mulch and a little bit of effort.
Applying mulch to the area that ponds is an immediate fix to allow water to runoff, but it doesn’t fix the underlying problem. To start, dig a trench in the direction the water should run off, and then fill it with gravel or another type of inorganic mulch that promotes drainage.
Overlay this new trench with the mulch that matches the rest of your landscaping, raking it, so it slopes away from your house. This adds volume to the low, wet area and directs runoff away from your house. This ensures that your landscape remains fruitful, your house doesn’t have water damage, and you don’t have to deal with recurring water problems.
Loose mulch is only useful when it’s applied evenly to the exposed soil on flat ground. If you have a sloped yard, you need to use a border system like stones to keep the mulch in place. Layer your mulch approximately one inch thick.
On slopes that decrease one foot vertically or less for every two feet of horizontal distance, a mulch thickness of two inches is best. However, if your slope is more dramatic, use layers up to four inches deep to prevent avalanches of mulch in your yard.
Mulch is a useful tool to prevent erosion, maintain soil temperature, protect your soil from the elements, and retain moisture. You can use mulch to prevent or encourage water runoff in your landscape. It keeps your plants healthy and makes your landscape visually appealing.
In conjunction with mulch, you can use a sprinkler or irrigation system to water your landscape and give your plants what they need. If your sprinkler is in need of repair, look no further than sprinkler rotor nozzles or backflow prevention parts to update your lawn’s efficiency.
