Ferns may be delicate above the soil, but below they need a rich, breathable mix to thrive. This blend combines high fertility with excellent structure, giving even the finest fern roots space to spread without resistance. Sand and perlite provide micro and macro air pockets, while coco coir and worm castings keep moisture levels steady and the nutrients flowing. Ideal for most common ferns and other houseplants that appreciate loose, moisture-retentive soil, like Rex Begonias and Tender Herbs.
