Since a bird's nest fern is an epiphyte, they don't really need soil to grow. Look over these articles and see if you can attach your fern to a pile of peat or compost in a basket or on a piece of wood. I'm including info about a staghorn fern because they are grown that way. Also, here is an article about starting another fern by propagating the spores.
