Are you struggling to control erosion in your garden or landscape? Groundcovers can be a simple, effective solution to this problem. In this article, we will discuss the importance of groundcovers for erosion control and provide recommendations for the best groundcovers to use. Whether you're dealing with a steep slope or want to protect your soil from heavy rainfall, we've got you covered. Read on to learn more.
The Importance of Groundcovers for Erosion Control
When soil is left bare, it is susceptible to erosion from wind, rain, and other natural elements. This can be especially problematic on sloped landscapes, where water runs downhill and carries soil with it. Erosion not only means soil loss, but it can also create unsightly gullies and damage nearby infrastructure. By covering bare soil with groundcovers, you can prevent erosion and promote healthy soil.
Choosing the Right Groundcovers for Your Soil Type and Climate
When it comes to choosing the right groundcovers for your property, it's important to consider your soil type and climate. Not every groundcover will thrive in every type of soil or climate. Here are some tips to help you find the best groundcovers for your specific needs.
- Know your soil type: Different groundcovers thrive in different soil types, so it's important to know what kind of soil you have in your garden or lawn. Some common soil types include sandy, clay, loamy, and silty. If you're unsure what kind of soil you have, you can perform a simple soil test or consult a professional landscaper.
- Consider your climate: The climate in your area will also play a role in determining which groundcovers will thrive in your lawn or garden. Some groundcovers prefer hot and dry climates, while others do better in cooler, moister environments.
- Research your options: Once you know your soil type and climate, you can start researching groundcover options that will work well for your specific situation. Some popular groundcovers for erosion control include creeping juniper, cotoneaster, and English ivy.

By taking the time to choose the right groundcovers for your soil type and climate, you can help prevent erosion and protect your property from the damaging effects of weather and runoff. Consult with a professional landscaper if you're unsure which groundcovers will work best for your specific situation.
Top 3 Groundcovers for Steep Slopes and Hillsides
When it comes to controlling erosion on steep slopes and hillsides, groundcovers can be a very effective solution. They not only stabilise the soil but also enhance the beauty of the area they are planted in. Below are the top three groundcovers that work best for this purpose:
- Creeping Juniper (Juniperus horizontalis)
- English Ivy (Hedera helix)
- Cotoneaster (Cotoneaster dammeri)
Creeping juniper plants grow low to the ground and spread horizontally, forming a dense mat ideal for erosion control. They also have a deep root system that helps to anchor the soil in place, making them an excellent choice for steep slopes. These plants are also very low maintenance and can tolerate dry conditions, making them an ideal choice for areas where water is scarce.
English ivy is an evergreen plant that can withstand cold temperatures and is a good choice for slopes where erosion is a problem. The ivy's strong roots will help hold the soil in place and prevent soil erosion from occurring. English ivy grows rapidly in the early stages of growth, so it will cover quickly even steep slopes and hillsides. It's important to note, however, that this plant can be invasive and should be monitored regularly to ensure it doesn’t take over the entire area.
Cotoneaster is a hardy shrub that can grow in a wide range of soil types and sun levels. It's best used when planted en masse as a groundcover, which creates a dense carpet of leaves and roots that bind the soil together. Cotoneaster is also drought-tolerant and requires little maintenance, making it a practical solution to erosion control on hillsides and steep slopes.
When selecting a groundcover for erosion control on hillsides and steep slopes, factors such as the plant's height, growth rate, and root strength should be considered. However, these three groundcovers are an excellent choice as they are low maintenance, adaptable and, most importantly, work well to control soil erosion.
Low-Maintenance Groundcovers for Busy Gardeners
Groundcovers offer a hassle-free alternative to traditional turf lawns and are an excellent way to control erosion. They require minimum upkeep, which makes them ideal for busy gardeners and those seeking to lower their water bill.

Tips for Planting and Maintaining Groundcovers for Long-Term Erosion Control
Planting groundcovers is an excellent solution for long-term erosion control. They reduce soil erosion and prevent sediment runoff, protect soil moisture, and provide natural habitat for pollinators and small animals. Here are some essential tips for planting and maintaining groundcovers for long-term erosion control.
- Select the right kinds of groundcovers. Choose groundcovers that are well adapted to your region’s climate and soil type. Native plants are often the best choice as they require less water and maintenance. Ensure that they are hardy and can withstand heavy rainfall and drought. Some excellent groundcovers for erosion control include Creeping Thyme, Carpet Bugleweed, Ajuga, and Creeping Phlox.
- Prepare the soil before planting. Proper soil preparation is essential for successful groundcover planting. Loosen the soil to a depth of 6-8 inches and remove any rocks, weeds, or roots. Add organic matter such as compost or aged manure to improve soil health and fertility. Ensure the soil is moist but not waterlogged, as this can harm the plants’ roots.
- Plant at the right time. It is best to plant groundcovers in the spring or fall when the soil is cooler, and rainfall is abundant. This gives the plants time to establish their roots before the hot summer or cold winter months.
- Water regularly. Newly planted groundcovers require regular watering for the first few months until their roots become established. After that, water only during prolonged droughts or when rainfall is insufficient. Overwatering can lead to root rot and other diseases.
- Mulch around the plants. Mulching helps to retain soil moisture, suppress weeds, and regulate the soil temperature. Use organic mulch such as shredded leaves, straw, or bark chips. Keep the mulch at least 1-2 inches away from the base of the plants to avoid rotting.
- Control weeds. Weeds compete with groundcovers for water, nutrients, and sunlight, and can quickly take over the area. Hand-pull weeds regularly or use a hoe to remove them before they can spread. Avoid using herbicides near your groundcovers.
- Prune as necessary. Some groundcovers may become too invasive or overgrow their boundaries. Prune them back as needed to maintain their shape and prevent them from spreading to unwanted areas. Enjoy your beautiful and functional groundcovers for years to come!
In conclusion, planting groundcovers is an excellent solution for long-term erosion control. By selecting the right kind of groundcovers, preparing the soil, planting at the right time, watering regularly, mulching around the plants, controlling weeds, and pruning as necessary, you can help your groundcovers to thrive and prevent soil erosion effectively.
