Around the USA, the topography changes drastically, leaving homeowners facing no one-size-fits-all solution to landscaping. For example, in hilly Southern California, nearly every yard has some slope to it! Hills can be challenging for irrigation, soil composition, erosion, and plant selection. It is essential to know how to use the topography to your advantage. Read on for all you need to know about landscaping on a slope!
Creative Ideas for Landscaping on a Slope
Most Californians, and many other homeowners in the country, have to landscape on a slope at some point in their lifetime. Here are some unique ideas to consider when starting your landscaping journey or maintaining your planting.
1. Natural Stone Retaining Wall
Stone walls are popular in landscaping because they have both form and function. They keep your yard looking natural yet can help turn your slopes into planting beds or separate different areas. Stone retaining walls require a significant initial investment of labor and money. However, once they are complete, they need little maintenance and can help grow plants in a planting bed microclimate.
2. Wood Retaining Structures
Wood is another material used to build retaining structures on a hillside. Using wood is less costly than building with stone and easier to remove, replace, or change locations. Wood planting beds and boxes can create a quaint cottage vibe to your hillside. Try adding wooden stairs and pathways to reach each planting box on your hillside. Planting beds and boxes are a charming feature because it can create different vibes in your yard based on your planting.
3. Layered Planting
Using your hillside to plant in layers is an easier option for low-maintenance gardeners. When planning your planting design, remember to place the most drought-resistant plants at the top of the slope, as these will receive the least water. As you water the hillside through sprinklers or drip irrigation, some water will eventually run down, so place the most water-needy plants at the bottom. Other than these requirements, have fun layering many colors and textures that complement one another.
4. Terraced Veggie Garden
Terraced hillsides have been used in farming for centuries all over the world – think the rice paddies of Asia or olive trees and orchards of the Mediterranean. Terracing helps your plants each get direct sunlight all day long and never be in shadow from other rows. Creating this garden on a natural slope is a great way to use the space. Build proper irrigation systems and place the most drought-resistant plants near the top!
5. A Spectacular Rock Garden
Turning your hillside into a rock garden is one of the easiest options for both design and maintenance. A rock garden is a modern, classy design that quickly becomes a feature in your yard with the addition of sparse, stand-out plants. This landscape design is also helpful in anchoring the soil to prevent erosion. If you’re not a fan of a modern design, try mixing larger rocks in with other plantings for a natural hill look.
How Do You Arrange Plants on a Slope?
The most critical consideration when planting on a slope is potential erosion problems. You must plant in a staggered or scattered formation to help water runoff disperse when flowing downhill. Ensure control of water flow at the top and slow runoff by terracing and contouring. Mulching, wide-spreading plant roots, and ground cover can help reduce surface runoff and hold soil. Also, planting leafy foliage can protect the soil from heavy rains.
What is the Best Plant to Plant on a Slope?
While plant choices usually adhere to your desired aesthetic, several types of plants thrive on a slope and help hold your hillside intact. For example, native plants have evolved over the years to adapt to the Southern California hills. They are the ideal choice for erosion control because of their adaptability and deep roots. They are also highly drought-tolerant. Some California natives for your slopes are sage varieties, California lilacs, manzanitas, and coyote bush.
What is the Best Ground Cover for a Slope?
The best ground covers for a slope are flat growing ground covers. They are planted at an angle, so they grow abundantly and spread over the ground. Just plant a budding version in a deep angled hole, nearly perpendicular to the hillside, and watch your hill turn green and lush. Creeping phlox, shrub or ground cover roses, and lamb’s ear are some of the best flat-growing ground covers for Southern California slopes.
How Do You Keep Dirt from Washing Away on a Slope?
The worst issue with landscaping on a slope is potential erosion. This happens over time when rain begins to dislodge and eventually erode the exposed soil, causing it to fall down the hill. Landscape design is critical – you must plant close together, incorporate a ground cover, and set rocks to cover the soil. Adding these anchoring elements will help to anchor the soil and slow runoff and erosion.
How Do You Landscape a Hill Low-Maintenance?
Landscaping a hill can be a daunting task, even for experienced gardeners. The most low-maintenance plan is to add hardscape elements and let the slope do the work for you. Sectioning off your hillside into terraces makes planting and maintenance easier. Add hardscapes such as brick walls, stone steps, wooden planter boxes, or metal garden beds. Choose an aesthetically pleasing material and let the natural shape of the hill create a low-maintenance landscape.
