Because they are lightweight, porous, and slightly acidic, they work especially well with acid-preferring plants and any planting situation that needs improved soil drainage and airflow around roots. The pack supplies enough material for topdressing containers, accenting terrariums, or mixing into potting media for better structure.\u003c\/p\u003e\n\n\u003ch3\u003eHow will these lava rocks improve drainage and root aeration?\u003c\/h3\u003e\n\u003cp\u003eThe rough, vesicular surface of lava rock creates tiny air pockets and channels that prevent waterlogging and encourage oxygen flow to roots.
