The degree of difficulty indisputably rises when you’re gardening on a slope (pardon the word play here). There are ways, fortunately, to deal with uneven landscapes that don’t involve just leaving it barren or giving it over to lawn.
Here, six smart solutions for the sloped garden.
1. Build a retaining wall.

Retaining walls are good for, well, retaining soil (and thus, preventing erosion), creating a flat surface for easy gardening, and often add an appealing architectural element to your garden. See Hardscaping 101: Retaining Walls.
2. Step it up.

Don’t fight your topography; instead, lean into it by highlighting the slope with a set of meandering stone steps.
3. Go for terraces.
