Rurtsva's pumice is natural and organic, with excellent permeability and a reported 55% water absorption rate, making it a versatile amendment for container plants, bonsai soil blends and indoor plant topdressing. It can be mixed with peat, akadama, lava rock, perlite and other components to tailor moisture retention and drainage for the plants you grow.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Rurtsva pumice improve drainage and reduce root rot?\u003c\/h3\u003e\n\n\u003cp\u003ePumice adds permanent pore space in potting mixes so excess water drains away while small pores hold accessible moisture for roots.
