This is the perfect soil blend for growing a wide variety of ferns. It is handmade from organic sphagnum peat moss, potting soil, and natural forest mulch/humus. This combination closely mimics the natural growing conditions of most ferns. (Ferns like soil that is well-aerated, acidic, rich in organic forest matter, and drains well while still remaining moist.) We grow all of our ferns using this potting mix and they are extremely happy.
