40mm Blue Slate

The 40mm Blue Slate we stock at Stone Zone is a favourite among landscapers and homeowners for good reason. Part of our extensive range of Decorative Stones, the 40mm Blue Slate stands out due to its striking deep blue colour and unique shape.

These blue slate stones truly come to life when wet, with their colours deepening to create an extra special effect. Unlike pebbles and chippings, our slate stones have a flatter shape and larger size, offering a distinctive look for your garden.

Our Welsh Blue Slate, like all our slate rockery, originates from North Wales. At 40mm, these stones are versatile and can be used in various garden designs. They're perfect for fish ponds as they are fish-friendly, and their larger size makes them ideal for different landscaping projects.

In addition to the 40mm size, Blue Slate is also available as 20mm Blue Slate and 40-75mm Paddlestones, providing options for various decorative and functional uses. Whether you're looking to enhance a water feature or create a unique garden path, our Blue Slate is a beautiful and practical choice.

40mm Blue Slate for Your Garden

If you want to re-decorate your garden without investing too much time and effort, the 40mm Blue Slate is your best bet. These garden stones are perfect for adding vibrant colours and textures to your outdoor space, instantly transforming your garden with minimal effort.

Welsh Blue Slate, approximately 40mm in size, is ideal for decorative garden features. However, it's important to note that these stones are not suitable for creating driveways and pathways. Their shape and size do not provide the stability required for walking or driving. Nevertheless, they can be used effectively in other areas of your garden, both front and back.

One excellent use for these Welsh Slates is as a striking garden border. You can design garden borders to your specifications, making them as wide or narrow as you prefer. Pairing these slates with natural features like Turf Grass or plant borders creates a harmonious and appealing look. They also make a fantastic border around your house, enhancing its curb appeal.

How to Create a Garden Pond 

Designing a modern, sleek garden water feature or a picturesque vintage pond can be a straightforward and affordable project, even for those with limited DIY experience. Here’s a step-by-step guide filled with tips and tricks to help you create a beautiful pond that will be the focal point of your garden.

Plan Your Pond Location: Start by designating an area in your garden for the pond. Consider the location carefully. If you place the pond under a tree, be prepared to frequently clean it of fallen leaves and debris. A shaded spot with partial sunlight is ideal to keep the water cool and reduce maintenance.

Determine Pond Size and Depth: Decide how big and deep you want your pond to be and whether you prefer a raised or ground-level pond. Plastic ponds are affordable and easy to find, making them a great choice. Place the pond in the designated area and mark the outline with spray paint. For a raised pond, use sleepers lined with water-tight fabric for the best results.

Excavate the Area: For a ground-level pond, dig out the marked area to the desired depth using a spade. Fill any gaps with scalpings to create a stable base for your pond.

Add Water and Features: Once the pond is in place, fill it with water. Consider using a solar-powered water pump for a constant flow, creating a serene water feature. Water fountains are a popular choice for adding movement and sound to your pond.

Enhance the Surroundings: Design the area around your pond to blend seamlessly with your garden. Use a variety of stones and chippings, such as Blue Slate, to create levels and add texture. Incorporate aquatic plants to enhance the natural look and integrate the pond with your existing garden greenery.

Note: Since our Decorative Stones are naturally sourced, variations in colour and texture may occur from batch to batch. If your stones appear dusty, hose them down to reveal their true colour.

By following these steps, you can create a stunning garden water feature or pond that will provide a peaceful retreat and a beautiful gathering spot for friends and family.
