Rock garden design

Rock gardens are captivating landscaping features that combine the raw beauty of natural stones with carefully chosen plants, creating a beautiful and low-maintenance outdoor space. The foundation of a remarkable rock garden lies in selecting the right rocks. In this blog, we’re excited to guide you through some popular rock garden design ideas using our high-quality rock types. Whether you love plants or just want your yard to look nice, our rock garden ideas will help you create a special outdoor space.

Choosing the Right Rocks

  1. River Rocks: These smooth, naturally round stones are a popular choice for rock gardens and often used in water features. Soil Kings offers river rocks ranging from 4 to 14 inches in size, adding a touch of elegance to your landscape.

  2. Limestone: With its warm hues and natural texture, limestone is ideal for creating a rustic and charming rock garden. Its light color also reflects sunlight, helping to maintain a cooler garden during hot summer months. Soil Kings offers limestone in three sizes: 10mm, 20mm, and 40mm, ensuring you’ll find the perfect fit for your taste.

  3. Pea gravel: This small, smooth rock is referred to as “7-10mm round natural washed rock” in Soil Kings’ product list. This popular product is ideal for garden beds or pathways and is often used as a base material for outdoor patios and playgrounds.

  4. Tan rocks: This rock features warm and earthy tones that seamlessly blend with a variety of design styles. Soil Kings offers it in a single size, 20mm, making it a suitable choice for high-traffic areas.

  5. Alberta Rainbow Rock: This rock offers a dazzling array of colors, providing your outdoor space with a unique aesthetic. Soil Kings offers it in both 20mm and 40mm sizes. Once washed, it reveals striking red, yellow, blue, and green hues. You can use Alberta rainbow rock for your pathways, garden beds, or focal points. 

Rock Garden Design Ideas

  1. Layered Elegance: Create depth by arranging larger rocks at the back of the garden and gradually decreasing their size towards the front. This layered approach adds visual interest and makes your garden feel more expansive.

  2. Sculptural Arrangement: Treat your rocks as art pieces. Position them in a way that showcases their unique shapes and textures. Complement the arrangement with low-maintenance plants that highlight the sculptural quality of the rocks.

  3. Natural Watercourse: Mimic the appearance of a dry riverbed by placing river rocks in a curving pattern through your garden. This creates a sense of movement and can be complemented with drought-resistant plants for a desert-inspired look.

  4. Rocky Borders: Define the edges of your garden beds with a border of pea gravel or smaller rocks. This not only adds a polished look but also prevents soil erosion and keeps your garden tidy.

  5. Terraced Heights: If your garden has slopes, use retaining walls made from stacked rocks to create terraced levels. This not only prevents erosion but also offers unique planting opportunities on each level.

  6. Colourful Contrasts: Mix and match different rock types and colours for a vibrant visual contrast. For instance, combine the warm tones of limestone with the cooler shades of Alberta rainbow rocks to create an eye-catching composition.
