With their unique texture and colouration, lava stones are a great way to bring your garden or landscape alive. So what is it about these volcanic rocks that makes them so special, and what's the best way to use them in your designs? Let's go through a few of the benefits of using lava stones for your landscaping projects.


Enhancing your landscapes

Lava stones have become a popular choice for landscaping and garden uses, since their natural, rustic appearance adds an intriguing element to outdoor spaces. They can be used to create pathways, borders, and decorative features in gardens or parks. The porous nature of lava stones also helps with drainage, making them ideal for areas prone to water accumulation.


Improving soil and plant health

Gardeners and horticulturists often utilise lava stones to improve soil quality and plant health. When mixed with potting soil, lava stones aid in improving drainage and preventing waterlogging, allowing roots to access oxygen more efficiently. Additionally, their porous surface can absorb and retain moisture, providing a steady supply to plants during dry periods.

Additional FAQs

  • How can you tell if a lava stone is real?

    Authentic lava stones have a rough and porous texture with air pockets visible throughout. They are lightweight and often have a deep black or dark brown colour. Genuine lava stones also tend to be brittle and can crumble easily.

  • How long do lava stones last?

    Lava stones are highly durable and can last for many years, even in outdoor settings. However, their lifespan can be influenced by factors such as exposure to extreme weather conditions and physical stress.

  • Do lava stones get mouldy?

    Lava stones are resistant to mould growth due to their porous nature, which allows for better airflow and prevents moisture buildup. However, if constantly exposed to excessive moisture, such as in a consistently wet environment, some mould growth may occur.

  • Are lava stones waterproof?

    Lava stones are not inherently waterproof since they are porous and can absorb moisture. However, their porous nature allows for water drainage, preventing waterlogging in landscaping applications.

  • What are the downsides of lava stones?

    While lava stones offer many advantages, it's important to consider their downsides. They can be brittle and prone to breakage if subjected to heavy loads or impact. Additionally, their rough texture may not be suitable for some applications where a smoother surface is desired.
