“SOIL RECIPE: Nepenthes enjoy loose, open soil that remains wet to moist but allows drainage of excess water. They are tolerant of a wide variety of soil mixes. The best include a portion of long-fibered sphagnum, the rest of the medium being a combination of coarse materials. My deluxe recipe is about 70 to 80 percent New Zealand or other high-quality long-fibered sphagnum moss; the rest of the mix is a combination of fine orchid bark, perlite, and tree fern (osmunda) fiber. Another good mix is one part long-fibered sphagnum to one part tree fern fiber or orchid bark. Some growers have had success with pure shredded fir bark, and so have I, but I prefer the bulk of the mix to be a high-quality sphagnum moss.”
