Whether you're personalizing a planter, crafting unique home decor, or enhancing your hydroponic system, our river rocks are the reliable, stylish choice for lasting results.

What Are River Rocks?

River rocks are natural stones shaped over time by the steady flow of water. Known for their smooth surfaces and rounded edges, they feature a naturally polished finish and an organic look that stands out in any setting. 

Typically made from materials like granite, quartz, or basalt, river rocks are chosen for their durability, uniform texture, and aesthetic appeal.

Unlike artificial stones or standard gravel, river rocks have no sharp edges, making them a safe and decorative option for both indoor and outdoor applications. 

Their rustic yet refined appearance adds a touch of natural beauty to a wide range of projects — from gardening and aquariums to crafts and hydroponic systems.

What Are River Rocks Used For?

River rocks are incredibly versatile and can be used for a wide variety of decorative and functional purposes. With their smooth texture, natural shape, and long-lasting durability, they’re a popular choice for adding both beauty and practicality to creative and landscaping projects.

Indoors, they’re perfect for enhancing planters, aquariums, and decorative arrangements. Outdoors, they’re commonly used in gardens, walkways, fountains, and leisure areas to create a natural, elegant look. 

They’re also great for crafts and educational activities like stone painting, and serve as an effective growing medium in hydroponic systems thanks to their excellent drainage and aeration properties.

Whatever the purpose, PGN’s river rocks deliver the perfect balance between function and design.

Common Applications of River Rocks

The uses of river rocks go far beyond decoration. These versatile stones provide practical and creative solutions for everything from family fun to professional gardening. Here are the most common ways they’re used:

Painting and Creative Crafts

Smooth, flat river rocks are ideal for painting with acrylics, permanent markers, chalk pens, and even alcohol-based inks. They’re widely used in schools, kids’ workshops, and DIY gift projects. Their natural surface inspires creativity and delivers beautiful results.

Gardening and Planter Decoration

River rocks help retain soil moisture, prevent weed growth, and add a natural touch to planters and garden beds. They’re also effective at keeping curious pets — especially cats — from digging in indoor pots.

Landscaping and Outdoor Decor

These stones are a popular choice in landscaping designs, whether for pathways, garden borders, decorative fountains, or relaxing zen areas. Their rustic yet elegant appearance brings balance and visual appeal to any outdoor space.

Hydroponic and Sustainable Growing

Expanded clay versions are ideal for hydroponic systems and indoor gardening. They offer excellent drainage, help oxygenate roots, and can be reused, making them a smart, sustainable choice for home growers.

How to Choose the Right Rock for You

Choosing the right river rock depends on your project and desired look. For painting, smooth, flat stones work best thanks to their even surface. In planters, gardens, or aquariums, medium-sized stones (1–3") help retain moisture and enhance the finish. 

If you're aiming for a clean or modern look, white and black stones are excellent options. For hydroponics, expanded clay pebbles are ideal, offering effective drainage and stable root support.

Usage Tips and Care Instructions

To get the most out of your river rocks, a few simple care steps can make a big difference. Before use, it’s recommended to rinse the stones under running water to remove any natural transport dust or debris — especially important for aquariums, planters, and hydroponic systems.

Indoors, the stones hold their appearance well and only need occasional wiping with a damp cloth. Outdoors, while they’re weather-resistant, periodic rinsing helps keep them clean and maintain their natural finish.

When not in use, store the rocks in a dry area to avoid excess moisture. With proper care, your river rocks will stay beautiful and functional across any type of project.
