The increase in air movement results in more oxygen reaching the roots of plants, encouraging better plant growth. Lava rocks make it possible for roots to spread without getting stuck as soil compaction never occurs and there is no risk of waterlogging, supporting strong plant health and life.
Porousness of Lava Rocks allow them to hold water while preventing overwatering. Water is absorbed and stored in them, and then slowly released to the plant roots as per their water requirements. That moisture-retaining property means you do not have to water as often and help provide proper soil moisture levels so the roots will not rot and perform better in every type of gardening.
