The Benefits Of Using Lava Rock In Landscaping

Lava Rock Is A Durable Stone
Lava Rock has many benefits. Durability is one of them. Lava Rock is an inorganic material. It doesn’t decompose, fade, or break down over time. The lifespan of the stone lasts many years and is one of the reasons why it is a favoured material for paths and walkways.

Lava Rock Is A Porous Stone
Lava Rock is a porous stone, making it beneficial for drainage applications and also helps aerate the soil when used in the garden.
Regarding drainage, Lava Rock can be used in French drains and run-off ditches to control the flow of water run-off away from the house. This is especially important in regions with heavy rain.
Lava Rock can also be used to improve drainage in potted plants by creating a base layer of rocks to facilitate drainage. Gardens and flowerbeds, on the other hand, are used to aerate the soil.
Weed Suppression
When lava rock is spread out throughout the garden and flower beds, it tends to suppress any weed growth you may have. This is done in a number of ways. Namely, blocking the sunlight and reducing the germination period of the weeds. It also blocks the weeds from pushing through the layer of lava rock.
Moisture Retention
The porous nature of lava rock means that it can absorb water and retain moisture. This retained moisture is released into the soil over time. This helps conserve water in drought-prone climates, such as Arizona.
Soil Temperature Regulation
Another benefit for your garden is the ability to regulate the soil temperature. As the lava rock heats up during the day, it releases that heat during the course of the night. This process helps maintain a stable soil temperature. This helps plants’ roots from being exposed to rapid temperature fluctuations.
Pest Resistance
Lava rock is a great pest control measure. Common garden pests such as termites and slugs don’t enjoy the texture of the lava rock. Lava Rock also isn’t a food source for them, so they tend to stay away.
