What are different types of drain rock for landscaping?

Drain rock, also known as drainage rock or gravel, is a versatile landscaping material used to improve drainage in various outdoor projects. Different types of drain rock are available, each with unique characteristics and uses. Here are some common types of drain rock for landscaping:

1. Pea Gravel: Pea gravel consists of small, rounded stones that are typically between 1/8 and 3/8 inches in diameter. It is often used in pathways, around plants, and in decorative landscaping features. Pea gravel allows for good drainage and is aesthetically pleasing.
2. River Rock: River rocks are naturally rounded stones that are typically larger than pea gravel, ranging from 1/2 inch to 6 inches or more in diameter. They are commonly used in water features, such as dry creek beds, and for decorative purposes in landscaping.
3. Crushed Stone: Crushed stone comes in various sizes, ranging from 1/4 inch to 2 1/2 inches in diameter. It is excellent for drainage due to its irregular edges and is often used as a base material for patios, driveways, and retaining walls.
4. Lava Rock: Lava rock is lightweight and porous, making it an excellent choice for improving soil aeration and drainage. It is commonly used as a decorative mulch, especially in xeriscape gardens, but it may not be suitable for high-traffic areas.
5. Decomposed Granite: Decomposed granite is a finely crushed granite rock that compacts well and provides good drainage. It’s often used for pathways, driveways, and as a base for pavers.

When choosing the type of drain rock for your landscaping project, consider the specific drainage needs, aesthetic preferences, and the intended use of the material. It’s also essential to prepare the base properly to ensure effective drainage and stability for your landscaping features.
