Everyday Usage of Hillside Ground Cover
Hillside ground covers are low-growing plants designed to thrive on slopes, embankments, and challenging terrain where conventional grass lawns are tough or impossible to maintain. Their dense foliage and intertwined root systems anchor soil, prevent erosion, and stop weeds from sprouting, bringing beauty and stability to otherwise tricky spaces.
Everyday uses include:
– Preventing soil erosion on slopes and banks
– Reducing maintenance (no mowing required!)
– Filling difficult-to-plant areas beneath trees or along driveways
– Adding color and texture with flowering varieties
– Suppressing weed growth, saving you time and effort
– Providing habitats for pollinators and beneficial insects
Whether you want a lush green mat year-round, a riot of seasonal color, or minimal maintenance, there is a hillside ground cover tailored for your landscape’s specific needs.
Benefits of Using Ground Cover on Hillsides
Choosing the right ground cover offers both practical and aesthetic rewards for your landscape:
Erosion Control
- Dense roots and foliage hold soil in place, drastically reducing run-off and washout on steep or bare slopes.
- Protects valuable topsoil and prevents gullies or bare patches from forming after rain.
Low Maintenance
- Most ground covers, once established, require little supplemental water or fertilizer.
- No mowing or edging is needed—just occasional trimming for shape.
Weed Suppression
- The tight mat of foliage from ground covers physically blocks sunlight so weed seeds can’t sprout.
- Fewer weeds mean less time spent weeding or applying herbicides.
Visual Impact
- Many ground covers, like Creeping Phlox or Vinca, add vibrant blooms in spring or summer.
- Contrasts of foliage color and texture enhance curb appeal year-round.
Habitat and Biodiversity
- Provides shelter, nectaries, and food for bees, butterflies, and garden-friendly insects.
- Berry-producing varieties attract birds and support wildlife diversity.
How to Choose the Right Hillside Ground Cover
The perfect ground cover depends on the unique conditions and goals of your hillside. Here’s how to narrow down your options:
1. Assess the Exposure
- Full Sun: Look for drought-tolerant varieties like Creeping Juniper, Sedum, or Big Blue Liriope.
- Shade or Partial Shade: Opt for Pachysandra, Vinca minor, Sweet Woodruff, or Ajuga.
- Mixed: Choose adaptable hybrids or plant a combination to suit variable areas.
2. Check Soil Type & Drainage
- Dry, Sandy Soil: Creeping Juniper, Sedum, Lamb’s Ear.
- Moist, Well-Drained Soil: Pachysandra, Ajuga, Creeping Phlox.
- Challenging Clays or Heavy Soil: Enhance with compost before planting and select tough varieties like Vinca or Cotoneaster.
3. Growth Habit and Spread
- Fast Spreading (‘Aggressive’): Vinca minor, Pachysandra, Wintercreeper.
- Slow/Controlled: Creeping Raspberry, Bath’s Pink Dianthus.
- Mat-forming: Creeping Phlox, Ajuga, Sedum.
4. Consider Maintenance Needs
- Low-maintenance/Set-and-forget: Sedum, Lamb’s Ear, Creeping Juniper.
- Requires occasional pruning: Vinca minor, Ajuga, fast-spreading types.
- Needs division or thinning over time: Some perennials to keep dense growth.
5. Aesthetic Preferences
- Blooms: Creeping Phlox (spring), Ajuga, Creeping Raspberry.
- Year-round green: Pachysandra, Vinca minor, Creeping Juniper.
- Textural interest: Lamb’s Ear, Big Blue Liriope, Cotoneaster.
Tips:
– Match the USDA Hardiness Zone of the plant to your climate.
– Avoid known invasives in your region or keep well-contained.
– For big slopes, a mix of types can create visual interest and ecological variety.
Tips and Best Practices for Planting & Maintaining Hillside Ground Covers
Preparing the Site
- Remove all weeds before planting, as they’re harder to manage once your ground cover is established.
- Loosen the soil and mix in compost or organic matter.
- On very steep slopes, consider installing erosion control fabric to hold soil in place while plants root.
Planting
- Stagger plants rather than planting in single straight rows for better stability and coverage.
- Space according to spread rate—closer together for fast coverage, wider for slow growers.
- Gently firm the soil around the roots and water in.
Establishment & Care
- Water regularly at first; most ground covers are drought-tolerant but need consistent moisture until established (first growing season).
- Mulch around new plantings to suppress weeds and retain moisture.
- Protect young plants from heavy rain (netting or straw) if the slope is prone to washout.
- Once established, reduce watering and let rain do most of the work.
- Trim or shear back fast-spreading types yearly to keep boundaries tidy.
Long-Term Maintenance
- Monitor for weed incursions; pull or spot-treat as necessary.
- In fall, clear dead foliage for varieties that aren’t fully evergreen.
- Every few years, divide or thin out overcrowded perennials for continued vigor.

FAQ
-
What are the best ground covers for sun-exposed slopes?
Plants like Creeping Phlox, Sedum, Creeping Juniper, and Lamb’s Ear thrive in full sun and are naturally tolerant of dry, exposed conditions, making them excellent for sunny hillsides. -
Which ground covers work best in shady hillside areas?
For shade, Pachysandra, Vinca minor (Periwinkle), Sweet Woodruff, and Ajuga are ideal. These plants tolerate low light and fill in under trees or on north-facing slopes. -
How do ground covers prevent hillside erosion?
Their closely-knit roots help anchor soil, reducing runoff and washing away during heavy rain. The foliage offers a protective canopy, slowing raindrops and wind. -
Are any ground covers evergreen for year-round coverage?
Yes, Creeping Juniper, Vinca minor, Pachysandra, and Big Blue Liriope all provide green, attractive foliage every season, ensuring year-round curb appeal and soil protection. -
How quickly will ground covers fill in a slope?
Most fast-growing varieties, such as Vinca minor or Creeping Phlox, start covering within the first season and can reach full coverage in 2–3 years, depending on spacing, care, and site conditions. -
Can ground covers stop weeds on a hill?
Absolutely! Once established, dense ground covers block light and space, significantly suppressing weed growth and reducing maintenance over time. -
What’s the best way to plant ground covers on a steep hill?
Prepare the slope by removing weeds and amending soil. Stagger plants in a zigzag pattern for better coverage. Use erosion fabric or mulch to protect soil until the plants establish. -
Are any ground covers drought-tolerant for dry hillsides?
Sedum, Creeping Juniper, Lamb’s Ear, and Big Blue Liriope are exceptionally drought-tolerant once established, requiring little to no supplemental water in ordinary years. -
Can I mix different ground covers on the same hillside?
Yes! Mixing compatible ground covers can provide visual interest, extend bloom times, and adapt to different microclimates (sun, shade) on the slope. Just choose varieties with similar water and soil needs. -
Will ground covers attract beneficial wildlife or insects?
Many flowering ground covers—like Creeping Phlox, Ajuga, or Cotoneaster—attract pollinators like bees and butterflies. Berry-producing species can feed birds and support healthy garden ecosystems.
