Disadvantages Of Decomposed Granite: What You Need To Know

If you're planning to use decomposed granite for your landscaping project, it's important to know that there are some disadvantages associated with this material. While decomposed granite is a popular choice due to its affordability and low maintenance requirements, it's not without its drawbacks.

In this blog post, we'll explore the various disadvantages of decomposed granite and provide you with the information you need to make an informed decision about whether or not it's the right material for your project.

The Pros And Cons Of Decomposed Granite

Decomposed granite (DG) is a versatile material that can be used in a wide range of applications, including as a substitute for concrete, gravel, or mulch. It's made from finely crushed granite and can range in color from gray to tan to brown.

Some of the advantages of using decomposed granite include:

• Affordability: DG is one of the most affordable landscaping materials available.
• Low maintenance: DG doesn't require any watering or mowing, making it a low-maintenance option.
• Easy installation: DG can be easily installed by homeowners and DIY enthusiasts.
• Permeability: DG is permeable, which means it allows water to penetrate through it, reducing runoff and erosion.

However, there are also several disadvantages associated with the use of decomposed granite, which we'll explore in the sections below.

1. Dustiness

One of the biggest complaints about decomposed granite is that it can be quite dusty, especially when it's dry. This can be problematic for people with respiratory issues or for those who live in arid areas where dust is already a problem.

To minimize dust, homeowners can try watering their decomposed granite regularly or adding a stabilizer to the material. However, these solutions may not be effective in all cases.

2. Erosion

While DG is permeable, it's also prone to erosion, especially when it's used on slopes or in areas with heavy foot traffic. Over time, the small particles that make up decomposed granite can be washed away by rain or blown away by wind, leaving behind uneven surfaces and bare spots.

To prevent erosion, homeowners can consider using a stabilizer or installing a border around their decomposed granite area.

3. Maintenance

While decomposed granite is generally low-maintenance, it does require some upkeep to look its best. Over time, weeds and grasses may grow through the material, requiring homeowners to pull them out manually or use an herbicide.

Additionally, decomposed granite may need to be topped off periodically to maintain its level and appearance.

4. Limited Color Options

While there are some variations in color when it comes to decomposed granite, the options are somewhat limited compared to other landscaping materials. Most DG is gray, tan, or brown, which may not be ideal for homeowners looking for a more vibrant or unique look.

5. Slipperiness

When wet, decomposed granite can become quite slippery, making it potentially dangerous for people to walk on. This is especially true if the material is installed on a slope or in an area where water tends to pool.

To prevent slipperiness, homeowners can try to install a rougher texture of DG or add a stabilizer to the material.

6. Hot Surface

Because decomposed granite is made from crushed rock, it can get quite hot in direct sunlight. This can be uncomfortable for people to walk on or sit near during hot weather.

To minimize this issue, homeowners can try planting shade trees or installing a pergola or other shade structure in the area where the decomposed granite is installed.

7. Not Suitable For High-Traffic Areas

While decomposed granite is a durable material, it may not be suitable for high-traffic areas like driveways or heavily used walkways. Over time, the material can become compacted and uneven, making it difficult to walk on or drive over.

8. Incompatibility With Some Plants

Because decomposed granite is alkaline, it may not be suitable for all types of plants. Some plants prefer more acidic soils and may struggle to grow in an area where decomposed granite has been installed.

Homeowners should research the specific plants they plan to use in their landscaping project before choosing DG as a material.

9. Limited Durability

While decomposed granite is a relatively durable material, it may not hold up as well as other materials over time. Heavy rainfall, freezing temperatures, and other weather conditions can cause the material to break down or erode more quickly than other landscaping materials.

10. Difficulty In Removing

If homeowners decide that they no longer want decomposed granite in their landscaping, removing it can be a challenge. The material is heavy and often requires special equipment to remove.

Additionally, decomposed granite can leave behind residue that's difficult to get rid of, which can make it challenging to install other landscaping materials in its place.

: Is Decomposed Granite Right For You?

Decomposed granite is a popular choice for homeowners looking for an affordable, low-maintenance landscaping material. However, it's important to consider the various disadvantages associated with this material before making a decision.

If you're willing to put in the work to maintain your decomposed granite area and are aware of the potential issues associated with the material, it may be a good choice for your project. However, if you're concerned about dustiness, erosion, or maintenance requirements, you may want to consider other landscaping materials instead.
