Gravel vs. Decomposed Granite: Choosing the Right Ground Cover for Desert Landscaping

Introduction

When backyard design it comes to desert landscaping, homeowners are often faced with unique challenges and opportunities. The harsh climate of regions like Phoenix, Arizona, calls for innovative solutions that conserve water and maintain beauty without excessive maintenance. One of the most crucial decisions in creating a desert-friendly landscape is selecting the right ground cover. Two popular options are gravel and decomposed granite. This article will explore the differences between these two materials, helping you make an informed choice for your outdoor space.

Gravel vs. Decomposed Granite: Choosing the Right Ground Cover for Desert Landscaping

Understanding the distinctions between gravel and decomposed granite can significantly affect the aesthetic and functional quality of your landscape. Each material has its pros and cons, making them suitable for different applications.

What is Gravel?

Gravel consists of small, loose stones that can vary in size from a few millimeters to several inches. It is available in various colors and textures, providing homeowners with numerous design options.

What is Decomposed Granite?

Decomposed granite (DG), on the other hand, is a natural stone product that has weathered over time into smaller particles—typically smaller than 1/4 inch in size. DG can be crushed or screened to create a finer texture ideal for pathways and patios.

The Role of Gravel and Decomposed Granite in Desert Landscaping

Both gravel and decomposed granite serve essential roles in desert landscaping by enhancing drainage while minimizing soil erosion. They provide necessary ground cover that helps retain moisture levels in the soil beneath while offering aesthetic appeal.

Key Differences Between Gravel and Decomposed Granite

| Feature | Gravel | Decomposed Granite | |-------------------------------|----------------------------------|------------------------------------| | Composition | Loose stones | Weathered granite | | Size | Varies widely | Typically less than 1/4 inch | | Color | Varied | Earthy tones, typically brown or gray | | Drainage | Excellent | Good | | Maintenance | Low | Moderate | | Aesthetic Appeal | More varied | Natural look |
