Frequently Asked Questions

  • What are landscaping rocks used for?

    Landscaping rocks are incredibly versatile. They can form retaining walls, act as edging for garden beds, cover bare patches of ground, improve drainage or create decorative features.


    Some people use rocks as a low-maintenance alternative to mulch, while others use them to highlight areas they want to stand out.

  • What size rocks are best for gardens?

    That depends on what you’re aiming for. Small river rocks and pebbles work well for garden paths, pond edges and tidy ground cover. Medium-sized rocks are good for filling beds or pathways, while large boulders are ideal for retaining walls, garden boundaries or feature pieces. Mixing different sizes often creates a more natural, balanced look.

  • Are rocks better than mulch for gardens?

    It comes down to preference. Rocks are tough, long-lasting and require very little maintenance, which makes them perfect for areas you don’t want to fuss over.


    Mulch, on the other hand, breaks down and feeds your soil with nutrients. Many people use both, rocks for structure and mulch for plant health.

Rocks for Every Landscaping Project

Every garden tells a different story, and the rocks you choose can really set the tone. River rocks are a favourite for low-maintenance spaces. They look neat, help with drainage and are great for edging or pond bases. If you need something with impact, boulder rocks are hard to beat. They work beautifully in retaining walls or as standalone features that instantly draw the eye.


If you’re after practicality, trench rubble and gabion baskets make sturdy, reliable foundations, while decorative stones give you the freedom to add texture and colour wherever you like. For something a little special, water feature rocks can turn a corner of your garden into a peaceful retreat with the sound of running water.
