The Complete Guide to Backyard Decomposed Granite Landscaping
Dreaming of creating a low-maintenance backyard oasis? Decomposed granite (DG) offers an affordable, stylish landscape solution for spaces both small and grand. With proper installation, these natural crushed stones can transform into stunning walkways, patios, garden borders, and more.
Keep reading to discover the beauty and versatility of decomposed granite landscaping for backyards. We'll explore creative design ideas, material considerations, construction tips, and maintenance musts so you can fully enjoy your unique DG retreat.
Benefits of Using Decomposed Granite in Backyard Landscapes
Unlike grass or mulch that requires frequent care, DG offers a fuss-free, environmentally friendly ground cover. Available in earthy neutrals like gold, red, brown and gray, these pea gravel-sized stones complement both rustic and contemporary garden designs.
Other advantages of decomposed granite yards include:
- Natural, organic appearance
- Permeability allows rainwater penetration
- Low cost compared to pavers or poured concrete
- Easy installation with minimal tools or equipment
- Long-lasting durability in low-traffic zones
With proper drainage and borders, DG resists erosion better than dirt or mulch. The coarse texture also deters weed growth. Less time and money spent on upkeep means more backyard leisure!
Creative Uses for Decomposed Granite in Landscapes
Beyond yards, DG suits various creative applications like:
- Garden pathways, patios, and seating areas
- Playspaces, dog runs, zen garden spaces
- Driveways, parking pads, and RV access
- Edging material between lawn and planting beds
- Tree rings or ground cover beneath shrubs
Mix colors and sizes for visual interest. Contrast fine particles against pathways lined with pebbles. Upcycle broken concrete chunks as funky borders. Get inspired by photos online or DIY television shows.
Design Considerations for Decomposed Granite Backyards
Successfully installing DG requires thoughtful planning. Determine high foot traffic routes versus relaxation zones. Note sun exposure, drainage issues, existing vegetation to preserve. Photograph from multiple angles to study spatial relationships and dimensions.
Site analysis informs ideal rock sizes, border choices and necessary base preparations. Pea gravel suits patios while larger stones stabilize heavily used walkways or inclined routes. Weed barriers, retaining walls and erosion control promote landscape longevity.
Climate Conditions and Weathering
Environmental factors affect installation methods and ongoing care. In rainy regions, compact DG with a hardener solution or binding agent into porous concrete. This minimizes washouts and preserves even coverage. Hot, arid climates rarely need stabilizers thanks to dry soils and sparse precipitation. However, occasional dust issues arise. Mitigate this by wetting particles during extreme wind or heat waves.
Incorporating Curves, Slope Variations
Ample space allows creative contours and multi-level terraces. Build pony walls from natural stone or wood to secure gradual inclines. Frame succulent gardens, water features and cozy fire pits. Strategically place boulders, rustic benches or weathered railway ties. Meandering garden pathways feel inviting versus boring straight lines.
Choosing Complementary Borders and Edging
Edging options prevent material migration beyond desired boundaries. Common choices include stone, pavers, treated lumber, corten steel and aluminum. For softer distinctions, trim edges with naturally erosion-resistant plants like sedums, thyme or creeping phlox. Their trailing foliage gently obscures any material changes.
Selecting the Best Decomposed Granite
Particle Size For Stability
Rock size significantly impacts durability and permanence. Standard grades include:
- Micro Fines - Flour-like powder used in stabilizer mixes
- Fines - 1/8 inch pea gravel for patios, paths
- 1/4 Minus - Up to 1/4 inch for driveways, parking areas
- 3/8 Minus - Gravel stones under 3/8 inch for heavy traffic
Smaller pieces compact better initially. However, larger stones resist indentation from furniture legs or footprints. Blended mixes balance aesthetic uniformity with strength. Play with sample bags before finalizing choices.
Color Options
Stones naturally range from golden honey to variegated reds, buff grey and inky black. Mimic surroundings with warm desert hues or bold contrasts. Blend multiple colors in mottled patterns across large installations. Setup color-coordinated zones for additional flair. Thoughtfully placed lighting illuminates rich nighttime depths.
Buying Recommendations
Plan 1.5 tons of DG per 100 square feet at 4 inch depths. This accounts for base preparation too. A 2-3 person crew spreads bags quickly with wheelbarrows and rakes. Forklifts facilitate bulk deliveries minimizing labor costs. Let supplier calculations and design drawings determine exact cubic yardage needs.
Constructing the Base and Foundations
Excavation, Grading the Yard
Eliminate existing vegetation through sod removal or herbicide treatments. Excavate several inches down, grading smoothly. Scrape away loose topsoil until hitting firmly packed terrain. Use line levels to identify and eliminate uneven spots or awkward contours.
For clay-based soils, till in 2-3 inches of crushed gravel, decomposed granite or paver base. These strengthen stability, facilitate drainage and discourage sinking or shifting long-term.
Installing Weed Barriers
Weed cloth blocks sunlight essential for germination. Overlap sheets 2-3 inches, stapling every few feet. Avoid punctures from shovel spikes or tools. Top with 1-2 inches of crushed stone like quarry process or chip stone for anchoring. It disperses weight evenly across the fabric barrier.
Compacting Layers, Leveling
Distribute DG across prepared bases using rakes and shovels. Smooth to desired grade heights referenced by perimeter borders like header boards. Mist lightly before compacting to 1.5 inch depths. Repeat adding thin layers and condensing until reaching proper 4 inch depths.
Tamp manually with hand tamp or rent power compaction equipment from home improvement stores. Ensure surfaces feel evenly firm and consistent prior to final laser leveling.
Incorporating Complementary Hardscapes
Further enhance backyard oases by thoughtfully incorporating secondary landscapes. Defining style preferences first allows cohesively layering compatible design elements over time.
Pathways, Patios and Garden Beds
Wandering gravel pathways feel pleasant underfoot versus harsh concrete. Encourage meandering through garden beds by incorporating organically shaped flagstone stepping stones. Repeat circular patio motifs echoed by tiered container plantings. Line gathering areas with low stone walls, preventing material creep.
Seating Areas, Pergolas and Serenity Points
Structure stunning focal points by framing permanent seating vignettes with wooden pergolas or pagodas. Use neutral-toned upholstered cushions and pillows to soften built-in DG benches bordered by flowers and grasses. Section off special reading nooks or tranquil water features as standalone sanctuary spaces.
Caring for and Maintaining the Landscape
Like any landscape investment, DG requires proper upkeep and monitoring, particularly years one through three post-installation. Prioritize the following maintenance tips for lasting backyard enjoyment:
