What Is Decomposed Granite?

If you’re thinking about updating your outdoor space, you’ve probably come across the term decomposed granite—often shortened to DG. It’s a natural material created by the gradual breakdown of solid granite into tiny particles, resulting in a soft, gravel-like surface that can be compacted into a stable, walkable layer.

Because of its organic look and practical benefits, DG has become a go-to choice for modern outdoor living areas in Sonoma and northern Napa County. It offers a natural texture that blends seamlessly with native plantings and California architecture, giving your landscape a warm, understated character that feels right at home.

Understanding the Basics of Decomposed Granite

Decomposed granite is simply granite that’s weathered over time into small particles of gravel, sand, and silt. When installed correctly, it compacts into a firm, durable surface that still feels natural underfoot.

There are a few common types you’ll encounter:

• Natural DG – Loose, unbound material straight from the quarry. It’s great for informal garden paths or areas where you want a very relaxed, organic look.

• Stabilized DG – Mixed with a stabilizing agent to bind particles, making it more durable and better for moderate foot traffic. Ideal for patios, walkways, and seating areas.

• Resin-bound DG – Uses a resin binder for maximum stability and longevity, perfect for high-traffic areas or commercial applications.

Compared to gravel or crushed stone, DG has a finer texture that compacts more smoothly. It offers a softer, more cohesive look while still supporting drainage and providing a stable surface.

Why Use Decomposed Granite in Landscaping?

Choosing decomposed granite for landscaping offers several benefits that make it especially appealing in high-end designs:

• Natural, warm aesthetic – The earthy tones and subtle texture feel organic and timeless.

• Permeable surface – DG supports drainage and helps reduce runoff, making it ideal for sustainable landscape design.

• Low maintenance – Once installed properly, DG needs minimal upkeep—just occasional raking or topping up.

• Cost-effective – More affordable than poured concrete or stone pavers, especially over large areas.

• Versatile applications – Suitable for pathways, patios, garden trails, seating areas, and even driveways with the right preparation.

If you're looking for a material that feels authentic to Sonoma and Napa landscapes while staying practical, DG is an excellent choice.

Design Ideas for Using DG in Landscaping

Decomposed granite landscaping can help you create a seamless, inviting outdoor space that feels tailored to your property. Here are a few ways you might use it:

• Meandering garden paths that guide visitors through native plantings or shady groves.

• Entryways and outdoor seating areas that blend naturally with the environment.

• Xeriscape or drought-tolerant designs where DG acts as a mulch-like ground cover while reducing water needs.

• Accents around native plant beds, helping define spaces without hard edges.

• Pairings with natural stone, wood, and native plants for a cohesive, regionally appropriate design.

The warm color palette of DG also works well with California’s architectural styles, from modern minimalist to classic wine-country estates.

Considerations for Installation and Maintenance

To get the best results with decomposed granite, proper installation is key. Here are a few things to keep in mind:

• Base preparation and compaction – A well-prepared base with good compaction ensures stability and prevents settling.

• Drainage planning and grading – Proper grading helps avoid pooling water and supports the permeable surface’s natural drainage.

• Use of stabilizers – For areas with heavier traffic, stabilized or resin-bound DG provides better durability and reduces maintenance.

• Long-term care – Occasional raking or adding fresh material keeps the surface looking clean and even.

Thoughtful planning and skilled installation help ensure your DG landscape remains beautiful and functional for years.

Is Decomposed Granite Right for Your Landscape?

Deciding whether DG is the right choice depends on your property’s unique needs. Consider factors like slope, intended use, climate, and the overall aesthetic you want.

Common pitfalls include poor compaction, choosing the wrong DG type for the intended use, or skipping edging that keeps the material contained. Working with an experienced landscape construction team can help you avoid these mistakes and ensure the finished result meets your expectations.
