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

WHAT ABOUT THE BUDGET FOR MY LANDSCAPE INSTALLATION?

There is extensive documentation of the value that intelligent, thoughtful landscape design can add to your home. In many parts of California, the value of the land surrounding your home is equal to, or sometimes even greater than the value of the home itself. Well designed, installed and maintained landscaping can lead to a substantial increase in the overall value of your home.

A budgeting rule of thumb for a complete landscape installation or renovation is 5-10% of the total value of your home, including the land. Therefore, if you own a $550,000 home, plan to spend between $27,500-$55,500 for a basic, functional landscape that will return up to 200 percent in value. Unusual materials mature specimen plantings, or elaborate hardscape will add to this figure.

The most successful landscape projects start with a realistic budget. Don’t hesitate to share your budget with the landscape designer. The designer can help strike a balance between special materials and cost-conscious choices to create a beautiful space that meets your functional, aesthetic, and budget preferences before you ask contractors for bids.

Finally, be sure to budget for the ongoing care and maintenance of your new surroundings. Good maintenance will protect your investment, as well as ensure many years of personal enjoyment and satisfaction.
