If you have a sloped lot, it can be challenging to stop erosion. Depending on how much your lot slopes, there are various methods you can use to try and prevent this erosion, some of which may cost more than others. There are multiple options for erosion control seed, either high-tech or low-tech, each of which can use different materials, including plants or wood.
Whichever method you choose, it is entirely possible to prevent erosion. If you don’t feel confident completing the job yourself, you can always contact a professional.
What is Erosion?
Erosion is the gradual loss of materials due to natural forces like wind and rain. Hillside erosion control products can prevent erosion from worsening and are particularly useful on sloped yards or lots.
When left unchecked, erosion degrades the soil or causes it to pile up at the bottoms of the slope. This can lead to additional problems by blocking streams or causing a backup of water along the slope. The extent of these issues depends on the degree of the slope and the type of soil. Sand-based soils generally wash away more easily than clay-based soils.
Preventing Erosion Using Plants
Erosion control seed may be necessary to prevent erosion and help to keep your slope even.
Usually, erosion control seed contains a mixture of different plants that grow easily and have large roots that can extend deep into the earth. This can help to keep the top layers of the soil in place, preventing them from washing away. It also reduces other competitive plants and weeds. Ideal plants for hillside erosion control products are those that grow in full sun or partial sun.
Great plants to use are
- California wild lilac (Ceonothus )
- Beardtongue (Penstemon )
- Creeping rosemary (Rosmarinus officinalis)
You can also use erosion control grass seed to prevent erosion on your sloped lot. Grass species with shallow roots are not suitable for holding the topsoil in place; however, using hydroseeding and choosing a mixture of erosion control grass seeds from various species, including perennial ryegrass, can help overcome this problem.
Other Methods of Erosion Control
If you are unable to use erosion control seed, you can use retaining walls on your sloped lot. Typically made of timber, cinder, stone, or brick, even a small wall can withstand large amounts of soil, though it may require planning permission.
