A bare dirt backyard presents immediate challenges, frequently leading to issues with mud during rain and pervasive dust in dry conditions. This exposed ground is also highly susceptible to soil erosion, especially on slopes, and offers a poor aesthetic for any home. Transforming this space into usable, stable ground requires a strategic approach, considering various methods that range in cost, maintenance, and intended function. The ultimate goal is to establish a durable surface that manages water effectively and improves the overall functionality of the outdoor space.
Preparing the Bare Ground
Before any new material is installed, the ground must be meticulously prepared regardless of the final covering choice. The first priority is to establish proper grading to ensure that water moves away from the house foundation and does not accumulate. A subtle slope of about one-eighth to one-quarter inch per linear foot is recommended to direct runoff to appropriate drainage areas, such as a swale or French drain.
Existing weeds and unwanted debris must be thoroughly removed, as failing to eliminate them now will lead to growth problems later on. For hardscape or aggregate projects, a commercial-grade landscape fabric, or geotextile, should be laid down after grading to suppress future weed growth from below. This fabric must be properly overlapped, by 10 to 30 centimeters, to prevent gaps where persistent weeds can emerge.
If a softscape option is the final choice, soil quality may need assessment, particularly for nutrient deficiencies or poor structure. Soil testing can determine if amendments, such as compost or specific fertilizers, are needed to support healthy plant growth. The physical process of loosening compacted soil, often through light tilling or aeration, creates a better seedbed for grass or groundcovers to establish strong root systems.
Softscape Options for Living Coverage
Softscapes involve the use of living, organic materials that offer environmental benefits, including cooling and rainwater absorption. For areas intended for heavy use, a traditional lawn remains a popular choice, though it requires regular maintenance like mowing and watering. Choosing between sod, which provides an instant lawn, and seed, the more economical option, depends largely on the project budget and the urgency of coverage.
Different grass species are selected based on the climate and light conditions, with some varieties having better shade tolerance or drought resistance. Low-maintenance groundcovers present an attractive alternative to a traditional monoculture lawn, thriving in areas where grass struggles. Spreading plants like creeping thyme, clover, or various sedum species can stabilize soil on slopes and reduce the need for frequent mowing.
Clover, in particular, fixes nitrogen into the soil, acting as a natural fertilizer for itself and surrounding plants. For larger areas or boundaries, dense planting beds utilizing shrubs and perennial borders can effectively cover bare earth and stabilize the ground. The extensive root systems of these plants physically bind the soil, which is an effective strategy for long-term erosion control.
Hardscape and Aggregate Solutions
Non-living materials, known as hardscapes and aggregates, provide durable, low-maintenance solutions that are ideal for high-traffic zones. Permanent structures such as patios made from poured concrete or interlocking pavers offer a stable, flat surface for outdoor living and entertaining. These solutions require a prepared sub-base of compacted gravel and sand to ensure longevity and prevent shifting over time.
For pathways and secondary areas, various aggregates like gravel and decomposed granite (DG) provide an affordable and permeable covering. Crushed stone, such as the widely used #57 limestone, is effective for driveways and areas needing solid drainage. Finer materials like pea gravel or DG are better suited for walking paths, offering a softer look but still requiring a defined border to prevent material migration.
Organic mulches, including wood chips or shredded bark, serve as a cost-effective ground cover that also benefits the underlying soil. A heavy layer of mulch, applied to a depth of 3 to 4 inches, is effective at suppressing weed germination and retaining soil moisture. This material decomposes over time, enriching the soil, but requires periodic replenishment to maintain the proper depth for effective coverage and weed control.
