Hold That Hill: Top Plant Choices for Slope Stabilization

Does your backyard hillside resemble a miniature ski slope after a heavy rain? You're not alone. Erosion on slopes is a common problem, but there's a beautiful and natural solution: plants!  The right vegetation can act like a living retaining wall, anchoring the soil with their roots and slowing down water runoff.

Here are some top plant choices to consider for your slope stabilization project:

Groundcover Champions:

• Gro-low Sumac (Rhus aromatica): This fast-growing champion thrives in tough conditions and boasts a dense network of roots that grip the soil. Plus, it offers vibrant fall foliage as a bonus!

• Creeping Phlox (Phlox subulata): A low-maintenance flowering choice, creeping phlox forms a dense mat with shallow roots that effectively bind the soil.

• Big Blue Lilyturf (Liriope muscari): This evergreen option forms attractive clumps with deep roots, perfect for holding soil in place.

• Mondo Grass (Ophiopogon japonicus): Low-growing and shade-tolerant, mondo grass is a versatile choice for slopes with less sun exposure.

Shrub Stars:

• Rockspray Cotoneaster (Cotoneaster horizontalis): This low-growing shrub spreads horizontally, creating a dense network of branches that root where they touch the soil, effectively anchoring the slope.

• Wintercreeper Euonymus (Euonymus fortunei):  Another spreading shrub, wintercreeper euonymus offers year-round interest with its evergreen foliage and attractive berries.

Considerations for Choosing Your Slope Squad:

• Sun Exposure:  Different plants thrive in different light conditions. Consider the amount of sun your slope receives when making your selections.

• Soil Type:  Sandy or clay? Knowing your soil composition will help you choose plants that are well-adapted.

• Maintenance Needs:  How much time and effort can you dedicate to upkeep? Some plants require minimal care, while others may benefit from occasional trimming.

Bonus Tip:  Combine different plant types for a multi-layered approach to soil retention. Deep-rooted shrubs can provide initial structure, while groundcovers fill in the gaps and create a living blanket to prevent erosion.

By strategically planting these soil-saving stars, you can transform your slope from an erosion hazard into a thriving and beautiful part of your landscape. Remember, consulting with a local nursery or landscaping professional can provide valuable advice on the best plant choices for your specific needs and climate zone. Happy planting!
