Not all soils are created equal, which is why we have formulated our own recipe for the best houseplant soil mix for your aroids, such as monsteras, philodendrons, anthuriums, pothos, and alocasias. With a blend of native New Zealand tree fern fiber, chunky pumice, and organic bark, we've produced a nice, light-weight aerated soil that mimics the tropical rainforest floor where many of our beloved aroids thrive.
