How to Landscape Along a House on a Slope

Walk the slope to get an idea of the depth of the rise and fall. Sketch the slope on graph paper and include the areas where it is most steep and slightly level. Also include existing features such as permanent fixtures, walkways, trees or fences so you work around them. Determine the amount of sunlight different parts of the slope receive and note on the sketch.

Install a French drain or drainage system at the base of the slope that carries excess rain or irrigation water to a predetermined outlet point or swale. Dig a level trench that measures 6 inches wide and 8 to 10 inches deep. Spread an inch of crushed gravel over the base before laying 4-inch-wide perforated drainage pipe over it, with the holes pointing downward. Spread agricultural fabric over the pipes before back filling with dirt.

Install boulders to add depth to the slope and break the monotony of the space. Dig a bed for each boulder to bury each one-third of its total height. Place smaller rocks in front of the boulders, and grow creeping plants such as ivy to provide color at varying heights.

Build terraces over steep sections of the slope to provide flat areas for growing plants. Level the land and install wood or stone retaining walls on each side. Level a small terrace yourself or hire a professional to grade a larger piece of land. Loosen the leveled soil and add shovelfuls of organic matter to enrich it.

Grow water-loving plants, shrubs or trees at the base of the slope. Use plants that do not rot if their roots remain in water for prolonged periods. Grow low-maintenance, ornamental plants on the terraced parts of the shrub for instant color and beauty. Keep the sunlight exposure of the particular spot in mind when selecting plants for it.

Dig narrow, meandering paths through the sloped area that connect different parts together while providing a secure footing. Fill a 3-foot-wide path and with crushed gravel, install tiles over it, or leave as it is for a natural, rustic looking walkway.
