How can you use volcanic rocks in gardening?

2025-01-06

Volcanic stone has a variety of uses in gardening, and here are some common ones:

Improve soil

Increased drainage: The porous structure of the volcanic stone improves soil drainage, preventing water retention in the soil and reducing the risk of plant root rot. When growing succulents and cacti, for example, a layer of volcanic stone can be laid on the bottom of the basin and covered with soil.

Improved breathability: The volcanic stone is breathable, allowing air to enter the soil better, promoting respiration and growth of plant roots.

Regulating soil temperature: It can also play a certain role in insulation, keeping the soil warm in cold weather and cool in hot weather.

Increased soil fertility: The volcanic stone contains a variety of minerals that can provide nutrients for plants.

As cover

Maintain soil moisture: Placing volcanic rock as a mulch around plant roots can effectively reduce water evaporation and maintain soil moisture.

Inhibit weed growth: The volcanic stone cover blocks sunlight and inhibits weed growth, reducing weeding effort.

Landscaping: Volcanic stone has a unique color and texture, such as black, red, etc., which can be used as a decorative element to increase the beauty of the garden.

Water features and filtration

Water feature decoration: Placing volcanic stones around water features such as pools and fountains in gardens can create a natural landscape effect.

Water filtration: The porous structure of the volcanic stone can absorb impurities in the water, playing a certain filtering role, helping to keep the water clean.

Other uses

Making bonsai: Using the natural form and texture of volcanic stone, you can make bonsai works with an artistic sense.

As a paving material: Laying volcanic stone in garden paths or courtyards is not only beautiful, but also has good drainage properties.

Planting medium: In hydroponics or soilless cultivation, volcanic stone can be used as a planting medium for plants, providing support and fixing plant roots.

 

In summary, volcanic stone has a wide range of applications in horticulture, which can effectively improve the growing environment of plants, while also playing a decorative and beautifying role.
