The Azure Colours of Blue Grey Slate
The natural colour variations in blue grey slate reveal a spectrum of shades when chipped, from light blues and greys, through to dark blues and charcoal. Slate chippings also often come with occasional, random coloured flecks, most notable when viewed up close.
It is also worth remembering that the colours exhibited in your garden will be dependent on whether they are wet or dry. Generally, expect to get a mid to dark blue slate hue when wet, and a paler blue/grey shade when dry. This can be especially important when you're planning to use them in water features or areas where they could be regularly sprayed by water.
The most common tones found in this blue gray slate stone are:
- 1Dark Blue: Deep, intense blue hues that may have subtle variations and darker accents.
- 2Medium Blue: A mid-tone blue that is not as dark as the deep blue, but still rich and vibrant.
- 3Light Blue: Softer and more subdued shades of blue, often with gray undertones.
- 4Grey: Most blue slate feature gray colours as well, ranging from light to dark gray.
- 5Charcoal: Dark, almost black shades of gray that add depth and contrast to the stone.

How to Choose the Right Sized Slate
Choosing the right sized blue slate garden chippings for your project comes down to a few practical considerations. The choice between the different sizes often depends on the scale of the project as well as the desired aesthetic outcome.
First, there is slate mini-mulch. With a particle size ranging from 2 to 14mm, it is best suited for planters, pathways, and low-traffic garden applications. It is not advisable for driveways due to its susceptibility to breakage under the weight of vehicles.
Next are 20mm blue slate garden chippings, which are ideal for projects such as smaller garden borders, paths, or as a decorative ground cover. Their smaller dimensions pack down flatter than the 40mm size, making them great for pathways. The size can also provide a more refined and intricate appearance.
On the other hand, the 40mm blue slate garden chippings are suited to driveways, larger border areas and as a mulch. They are also ideal for ponds and as base for larger rockeries.
Last, but not least, blue slate paddlestones (which are generally 60mm diameter or larger) are most often utilised for larger landscape projects because their size allows them to stand out and create a robust, dramatic aesthetic. This can make them ideal for use in features like rockeries, ponds, and water features where the larger scale of the chipping will be more apparent.
Before making a decision, it's a good idea to see samples of the aggregates together or create a mock-up to visualize how they will look in your specific outdoor setting.

Driveways
Using blue slate chippings for driveways can greatly improve the appearance and functionality of your driveway borders, but they can be problematic when applied as the surface. While these stones are mostly hard-wearing and the 20mm size is quite capable of binding together, they do tend to deteriorate with heavy traffic.
If your driveway usually experiences heavier traffic, perhaps it would be best to instead opt for blue granite chippings, which is specifically designed for this purpose and can ensure the best possible results. With proper installation and maintenance, a blue stone driveway can provide a secure and attractive surface for many years to come.
Tips for Installing Slate Chippings
Even for the novice landscaper, employing proper technique is essential for achieving a professional finish when laying blue slate aggregate in your garden. While we go into detail in how to lay slate chippings, here we cover the basics in order to help you prepare.
To start, it is recommended to dig out the area to a suitable depth for your chosen size of chip and purpose (see below), before raking the base area even. To get the best results for pathways or driveways, adding a sub-base is key to achieving a lasting result. Therefore, it is recommended that the area is also compacted using a flattening tool.
Before spreading the chips, you can minimise future maintenance by laying a heavy duty membrane for the prevention of weed growth. This will also ensure a clean surface for the stones. However, compacting the area with a sub base can also be effective, without the need for a weed membrane for those who desire a more natural installation.
For heavy-duty applications like driveways with high traffic, it is often advisable to use larger sized 40mm blue slate chippings. This will ensure a durable and longer lasting surface.
Caring for Your Chipped Slate Garden
Maintaining your blue slate chippings feature is a relatively simple task, as these stones require minimal upkeep. While they are most effective in controlling weed growth, and can significantly reduce the need for constant weeding, they still require occasional maintenance.

There are a few ways simple ways to go about cleaning your slate chippings. They may be washed down with a power hose, or you can also create a large sieve and hose them down to remove any dirt or debris. By performing occasional maintenance and keeping the stones clean, you can guarantee that your blue slate garden remains beautiful and functional for very many years to come.
