Adding a rock garden to your yard is a creative way to add depth and dimension to a flat or mundane space, or to introduce an element of surprise. The rugged appearance of rock adds earthy appeal, connecting a manmade landscape to the natural world.

Rocks can be used to define a slope, act as a substitute for a lawn, or become a solution to an area where little will grow. Different areas of the yard such as walkways and beds can be outlined or separated with an attractive arrangement of rocks, pebbles or gravel. A rock garden can range from a complex large-scale project with many aspects and layers, to something as simple as a small corner adorned with gravel and river stones. Even a container can become a miniature rock landscape.

Rock gardens are low-maintenance and lend year-round structure to the landscape. In order for your finished project to have cohesion, it should be well thought out and designed. Here are some basic principles to get you started, along with a list of recommended plants.

How To Build A Rock Garden

  • Make a list.

In order to have the right materials on hand, make a list of what you need.

  • Source materials.

Peruse local garden centers, home improvement stores and specialty rock suppliers to see and compare materials before buying. For the budget-minded, Craigslist and Freecycle often have listings from people looking to get rid of rock materials. Consider rock quarries or natural areas that allow rockhounding.

  • Vary the rocks.

To create contrast and visual interest, vary the size and shape of the rocks. Use a mix of materials such as stones, pebbles and gravel.

  • Placement.

Use a few well-placed larger rocks as primary focal points to anchor the space and install those first. Allow space between the rocks for plants to grow. Smaller complementary stones or gravel placed around the larger rocks will unify the design.

  • Keep color in mind.

Select larger rocks in lighter hues so the landscape doesn’t feel dark and heavy. Vary the color and tone of other materials to lend contrast and visual interest.

  • Instill order.

To keep the design from looking too busy, choose rocks with complementary colors and shapes. Lay out swaths of the same pebbles or gravel rather than mixing too many materials together.

How To Plant A Rock Garden

  • Soil matters.

Create an environment that is hospitable to your chosen plants. Alpine plants and other drought-tolerant plants will need sandy soil with sharp drainage. Others, such as ferns and hostas, will need richer soil and more moisture.

  • Pick the right plants.

Choose plants that will thrive in your climate. Traditional rock gardens include varieties that are alpine in origin, as the conditions simulate their native habitat. Rock garden plants tend to be smaller to complement the scale of the rocks. Use perennials, ornamental grasses and small shrubs to add vertical height. Creeping groundcovers will soften the appearance of the hard rocks. Add sturdy bulbs such as narcissus, wild tulips and alliums for contrast. Incorporate evergreen dwarf and creeping conifers for year-round interest. For a shade garden, choose mosses, ferns and hostas.

  • Complement and contrast.

To lend cohesion, choose plants with harmonious or complementary colors to the rocks. Use a mix of plants with flowers and foliage interest and combine upright and creeping forms.
