In essence, igneous rocks are formed through the cooling and solidification of magma ( or lava). As hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that cause it to cool, solidify, and crystallize.

Yes, you can mix lava rock and fire glass in a fire pit. The two work very well together in a variety of ways to protect your investment and enhance your fire pit experience at a lower cost.

Plants in lava rock can grow into the porous, pocked surface and survive without much root space. For this reason, choose plants that have shallow root zones. Lava rock houseplants are also common gifts and novelty gardening situations.

Succulents and cacti naturally grow in sandy soils that drain quickly, and their roots should never be left in wet soil. Also, using rocks and pebbles on your soil can improve the aesthetic appeal of your succulents. Succulent needs soil to survive, and they cannot survive on rocks and gravels alone.

The main purpose of placing pebbles on the bottom of the potted succulent plant is to enhance drainage. Succulents and cacti naturally grow in sandy soils that drain quickly. The rocks help move water through the soil to prevent the roots from rotting.

As a rule, succulent plants do not mind crowding whether the plants are grouped in one container or are alone and fully filled out in the container. Transplanting a plant that has filled its container will generally allow the plant to experience a new spurt of growth.

Succulents do not like to sit in wet soil for very long, therefore they need a well draining soil. The best soil for succulents allows for fast air and water exchange in the root system of the plant. What I like to use is a combination of cactus potting mix and perlite. The perlite is for better drainage and aeration.
