Lava stones are porous, so they store water and offer roots optimal support. But not all plants are suitable for planting lava stone. Find out which plants thrive here and how to plant your lava stone step by step.

Plant the lava stone step by step
A question that often comes up when planting a lava rock is whether soil is needed. Unfortunately, this cannot be said in general, as it is not necessary for some plants and makes sense for others. In general, larger plants need more soil than smaller ones. To avoid the problem, simply put some soil on the stone, because it won't do any harm.
Then proceed as follows:
- Soak your lava rock in water for about an hour to soak it up.
- Then place your plants on the stone. If possible, plant them in small hollows or bumps where they are less likely to shift and leave some soil on the roots.
- Then, tie down your plants to hold them in place until the roots find support. After a few weeks, you can remove the bands or straps.
Which plants are suitable for the lava stone?
Planting with moss is particularly easy. It looks like a small grassy landscape on the rocky ground. It can be excellently combined with low-growing grasses.
Another very popular variant for lava stone planting are succulents. They need little water and get along with little nutrients and without soil, so they are predestined for the lava stone. If you have your lava stone outside, you should make sure that your plants are hardy. Hardy succulents are e.g. houseleek, other sedum species or starroot.
maintain lava stone
As already mentioned, the lava stone stores moisture. So if you have it in the garden or on the terrace, all you have to do is enjoy the planted stone. The rain provides enough water. You should only help with a little water if the drying phase is longer. Young succulents or recently planted succulents should be covered over the winter to prevent frost damage.
If the lava stone is in the house, you should water it from time to time.
