To thrive, aroids require well-draining soil. The ideal aroid soil mix recipe combines organic matter, such as orchid bark or coco coir, with inorganic materials like perlite or pumice. This blend provides aeration, moisture retention, and drainage, ensuring optimal root development. The ratio of these components varies depending on the specific aroid variety and environmental conditions. Proper mixing and sterilization of the soil enhance its properties, supporting the health and growth of these captivating plants.
