Decomposed Granite Landscaping: Pros, Cons & South Pasadena Tips

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.

Tips for Using Decomposed Granite in South Pasadena

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.
  • Add Edging: Install borders to keep the material contained and reduce spreading.
  • Incorporate Plants: Surround DG areas with drought-tolerant plants for added beauty. Learn more about drought-tolerant plants for Pasadena.

Frequently Asked Question

WHAT ARE THE DIFFERENCES BETWEEN LANDSCAPE DESIGNERS, LANDSCAPE ARCHITECTS, AND LANDSCAPE CONTRACTORS?

Landscape designers may provide design ideas, landscape plans, planting plans and lighting plans. Some also offer installation-related services such as material selection or plant placement. While they may provide conceptual ideas on garden structures, irrigation, and hardscape layout, most are not licensed to provide construction drawings. Likewise, while they may work closely with contractors overseeing the aesthetic elements of an installation, most are not licensed to provide actual construction services. Their education is in residential design, which emphasizes design strategies, hardscape options, and plant materials appropriate for residential projects.

Landscape architects are licensed by the State of California and, in addition to the plans typically provided by a landscape designer, are qualified to produce construction-ready plans that may include complex retaining walls, grading and drainage plans, and physical structures. Their training emphasizes design for large public and commercial spaces such as parks and commercial landscapes, although some specialize in residential projects.

Landscape contractors are licensed to install the designs created by landscape designers and landscape architects. Some are design/build companies, and provide design and maintenance services as well. When working with a design/build firm, be sure to clarify the design process used and whether you will receive landscape drawings for your review and approval or just a verbal or written description of the landscape to be installed. Some design/build companies bundle the design fees with the cost of construction, but it is still important to understand the design cost component should you decide to hire a different company for installation.
