Lavagranulate is not the same as lava granulate. There are different products with different properties. Lavagranulat is used as a sub-mix in indoor potting soil, in the garden as an additive for the garden soil, as a decoration of beds and potted plants and even in the pond it is used.
Lava granules are a product of fire-spewing volcanoes. The rock is of volcanic origin and has practical and visual benefits. In any case, it is a pure natural material. Ideal for mixing is a grain size of 8 to 16 mm. The small stones have a porous surface. They improve the soil to increase the oxygen supply and stabilize the water balance. When casting, no earth is washed away. In addition, slurries, especially in the clay soil, avoided. The lava granules absorb water and thus keep the soil moist for longer. It does not rot and is odorless.
Lavagranulat for indoor plants
You can use the lava granules as a replacement for hydroponic spheres or seramis. Important is the grain. 4/16 is ideal for this purpose. It is unfavorable to take the bare plant root without soil and place it in lava granules. Earth should always be present around the roots. This makes it easier for the plants to absorb nutrients. These often have to be transformed by soil organisms so that they can be absorbed. In addition, the fine dust content of the granules can stick to the roots. This rather prevents the absorption of nutrients. For this purpose, the granules can also be used for mixing under normal soil. This is ideal for cacti and succulents, for example. The small, light stones provide sufficient air in the root area and bind moisture that the actual soil is not too humid for the plants.
Lava granules for rockeries, stone or pebble beds
For rockeries, the granules are particularly practical. The lava rock stores solar heat. This provides ideal development opportunities for the plants. In the stone or pebble bed, which are now very popular because they offer a good alternative to care-intensive lawns, the lava bunnies are ideal. They look good and convince with their practical properties. They are used for raked surfaces, representative framing of solitary trees, Japanese style miniature landscapes and many other design ideas. The good news is that wild herbs through the layer of lava granules hardly have a chance to penetrate. This significantly reduces the maintenance effort.
Lava granules for the garden
In the garden, lava granules are often used to improve heavy soil. It is a very natural soil improvement, before many hobby gardeners attach great importance. The floor is loosened, ventilated and heated. The water storage power of the soil is increased and the granules also provide important minerals and trace elements. For light soils, the water storage capacity of the soil is increased. It is used approximately in the ratio 4: 1. Lavagranulate protects the soil from dehydration. Another side effect is that the germination of approaching seeds is reduced. Lava granules can be used as a covering for garden paths, without the soil being compacted. The stones are also suitable as splash protection around the house.
Lavagranulat for potted plants
Lavagranulat is well suited as a drainage layer and protects against waterlogging and associated decay. It is also often used as a substrate for Mediterranean hydroponics. A layer of lava bunnies on the soil of the planter also creates a Mediterranean flair.
Lavagranulat for the garden pond
Here, the granules help to stabilize the biological balance in the pond and reduce pollutants. The stones are applied to the pond bottom or stored in the filter system. In the porous surfaces, microorganisms settle after a short time, which clean the pond water flowing past. Nutrients and pollutants are degraded.
