DG or decomposed granite is a popular inorganic mulch no matter if you live in Pacific Beach or in North Park however it should be noted that it does have its pros and cons. Here are a few things to considering before using DG in your landscape.
Pros of using DG
- Natural Appearance:
- DG has a natural and rustic appearance, blending well with the surrounding landscape. It provides an earthy and organic feel to outdoor spaces.
- Permeability:
- Decomposed granite is permeable, allowing water to pass through easily. This can help with drainage and prevents water runoff, making it an environmentally friendly option.
- Low Maintenance:
- DG requires minimal maintenance compared to other landscaping materials. It doesn’t need frequent watering or mowing, making it a low-effort solution for homeowners.
- Cost-Effective:
- It is often more cost-effective than other hardscape materials like concrete or pavers. This makes it a budget-friendly option for landscaping projects.
- Versatility:
- DG is versatile and can be used for various applications such as pathways, driveways, patios, and garden areas. It can also be easily shaped to fit different design preferences.
- Weed Prevention:
- When properly installed with a stabilizer, DG can inhibit weed growth. This can save time and effort in weed control compared to traditional lawns. However the stabilizer will reduce permeability.
Cons of using DG
- Stability Issues:
- Decomposed granite may shift over time, especially in high-traffic areas or during heavy rain. This can result in uneven surfaces and may require periodic maintenance. Occasional tamping of the surface can improves stability issues.
- Compaction and Erosion:
- In areas with high foot traffic or heavy rains, DG can become compacted, leading to a harder surface. Additionally, erosion may occur, affecting the evenness of the surface.
- Color Fading:
- The color of decomposed granite can fade over time due to exposure to sunlight and weather conditions. This may require periodic replenishment or the application of color-enhancing sealants.
- Accessibility Issues:
- DG may not be the best choice for those with mobility issues as it can be difficult to navigate, especially for wheelchairs or walkers.
- Initial Dustiness:
- When first installed, decomposed granite can be dusty, which may be a temporary inconvenience. This can be mitigated by watering and compacting the material during installation.
- Limited Plant Support:
- In areas with heavy rainfall, decomposed granite may not provide adequate support for some plant types. Consider the specific needs of your plants and landscape design.
