Grey limestone gravel is a decorative aggregate that can add a clean and modern look to your outdoor spaces. It has a light grey colour that reflects sunlight and can brighten shaded gardens, making them feel more spacious. This gravel is also very durable and can withstand high levels of traffic, which makes them ideal for use on driveways and walkways. It provides a neutral backdrop that can complement both vibrant and subdued planting schemes.

However, it's important to note that grey limestone gravel is alkaline, which means it can harm plants that require a pH-neutral or acidic environment. They are not suitable for use in acidic soil gardens or planted areas such as beds or borders. Despite this limitation, grey limestone gravel is very budget-friendly, so you can upgrade your outdoor spaces with a visually striking, low-maintenance, and highly versatile feature without spending too much money.

Dove grey limestone gravel is generally low maintenance, especially when a weed control fabric is installed underneath to suppress weeds, with most work limited to the occasional removal of debris. Occasional power washing is advisable to maintain the original colour and prevent build up. Natural quarry materials also may have dust, which should be hosed off with water at the time of installation.

For areas with heavy footfall, such as paths or footpaths, replenishment of gravel may be required over time to maintain depth and coverage. For more on how to clean gravel, read our article: how to clean garden stones.
