by BuildCal Landscape / 05/17/2025 / Decomposed Granite

Why Decomposed Granite is Gaining Popularity in South Pasadena

Decomposed granite (DG) is becoming a favorite material for landscaping in South Pasadena due to its affordability, natural appearance, and versatility. At BuildCal Landscape, we specialize in helping homeowners incorporate DG into their outdoor spaces while addressing its pros and cons. Let’s explore how decomposed granite can enhance your landscape.

What is Decomposed Granite?

Decomposed granite is a naturally occurring material made from weathered granite. It has a rustic, earthy look and is commonly used for pathways, patios, driveways, and garden beds. Its permeability makes it an eco-friendly choice for South Pasadena’s dry climate. For more inspiration, check out our article on best hardscaping materials for Encino’s climate.

Common Uses of Decomposed Granite

  • Pathways: Creates a natural, low-maintenance walking surface.
  • Patios: Offers a rustic alternative to traditional paving materials.
  • Garden Beds: Acts as mulch to retain moisture and suppress weeds.

Pros of Using Decomposed Granite

Decomposed granite has several advantages that make it a popular choice for landscaping projects:

Advantages of Decomposed Granite

  • Affordability: DG is cost-effective compared to other hardscaping materials like pavers or concrete.
  • Eco-Friendly: Permeable surface allows water to drain naturally, reducing runoff.
  • Natural Aesthetic: Blends seamlessly with South Pasadena’s natural surroundings.
  • Low Maintenance: Requires minimal upkeep when stabilized or sealed.

Cons of Using Decomposed Granite

While DG has many benefits, there are some drawbacks to consider before incorporating it into your landscape:

Disadvantages of Decomposed Granite

  • Durability Issues: Can erode or shift over time without proper stabilization.
  • Weed Growth: May allow weeds to grow if not properly maintained or stabilized.
  • Heat Retention: Absorbs heat, which may make it uncomfortable underfoot in hot weather.

To maximize the benefits of decomposed granite and minimize its drawbacks, follow these expert tips tailored to South Pasadena’s climate:

South Pasadena-Specific Tips

  • Stabilize the Surface: Use a stabilizer to prevent erosion and create a firmer surface.

Frequently Asked Question

HOW DOES THE DESIGN PROCESS WORK?

While the process may vary depending on the designer, the client’s needs, and the complexity of the project, most residential design projects include the following:

Initial Consultation, This is a chance to meet the designer and review the requirements and objectives of the project. Many designers charge for this visit, so to get the most out of the experience, ask the designer the best way to prepare and be sure you understand exactly what will be covered at this meeting.

Concept Plan. After listening to your ideas and priorities, the designer analyzes the site’s character, strengths and problems, and then develops one or more alternative concept plans for review.

Master Plan. The final master plan represents the culmination of your choices with the designer, and typically includes a complete spatial layout for your outdoor living spaces and other hardscape or architectural concepts.

Planting Plan. This is a working drawing from which the garden will actually be planted, and includes botanical names, container sizes, specific plant locations, and planting instructions to the contractor.

Additional Plan Documents. Depending on the scoop of your project, your designer may also provide a lighting plan, specialized guidelines on planting or irrigation, or notes and sketches on design elements such as water features or furniture and accessories placement.

Installation Assistance Many landscape designers will assist you in soliciting and reviewing construction bids, including referring contractors appropriate for your project. Others may choose to provide drawings only. Designers often stay involved throughout the installation phase to advise on design modifications, material selections and purchase and placement of garden art and accessories.
