40mm Green Slate for Your Garden

Green Slate decorative stones are the perfect addition to a garden that is looking for something to give it that finishing touch as well as a natural feel to it. 

Due to it's slightly larger size, Green Slate is best used as a decorative feature, as opposed to using it for practical uses such as a pathway or a driveway. A popular feature people go for is surrounding hard landscaping features, such as garden paving or grass areas. 

Green Slate is also very effective when placed in your front garden. Many people don't have time to tend to their front garden, so are just looking for something that is low maintenance that looks nice when guests arrive. For that reason, Green Slate can be placed on top of Weed Fabric in an area in the front garden that just gets looked at. You could also use it as a border around the front or sides of your house.

40mm Green Slate for a Garden Pond

If you're in the fortunate position of having a garden pond to admire, Green Slate makes the perfect decoration for it! The green/silver colours of Green Slate are best admired when the stones are wet, therefore, many people place these Slate stones just around the outside of the pond, as well as just under the water.

With this natural stone being completely lime free, it makes it perfectly safe to place in a garden pond that is also inhabited by fish and other animals. These could act as steps for certain creatures like frogs, and create a multi-layered pond.

How to Create a Garden Pond 

Whether you're looking to create a modern, sleek garden pond that sits in the middle of your garden and is very minimal with decoration, or you want a completely natural-looking pond to encourage a host of wildlife to your garden, we have created a handy guide for you to follow if you're up for the challenge of creating your very own garden pond! It's a lot cheaper and easier than you may think, read on to find out more!

1. The first step is to plan where in the garden you want to place your pond. Before you make your mind up, think about the following points; what would be the best place? We would suggest avoiding putting your pond under trees, as you'll be constantly ridding it of all the falling leaves which can be a pain to do and contaminate your pond water. Somewhere that gets a fair amount of shade and a little bit of sunlight would make an ideal pond placement, so the water doesn't get too warm.

2. Next, decide on the size you want your pond to be, and where you're going to buy it from. If you want a ground-level pond, you can buy plastic ponds from your local garden centre. If this is the case, mark the desired area with spray paint to ensure it is the desired size. If you're looking at creating a raised pond, you could either use retaining Sleepers lined with a plastic sheet or even upcycle an old washing basket!

3. If you're creating a ground-level pond, dig out the desired area to the correct depth. You can use Scalpings to fill in any gaps after you've added your pond.

4. This is the fun part where you can add your water! People have also bought water pumps that are solar-powered to create more of a water feature; you can even add a small water fountain to give it the wow factor!

5. Lastly, consider the look that you want your pond to have. If you like the idea of a natural rockery pond, purchase larger Rockery stones with additional, smaller stones like Green Slate. Take a look at some water plants from your local garden centre, and make your pond look exactly as you want!  

PLEASE NOTE: Due to our Decorative Stones being a naturally-sourced product, there will always be some variation from batch to batch, especially in terms of colour. On occasion, your garden stones may be very dusty; we recommend hosing your new stones down to wash them and reveal their true colour.
