Nearly all ferns prefer a soil that is moist and well-draining. Most do best in slightly acidic to neutral soil, from 4.0 to 7.0 in pH, but some, such as the maidenhair fern (Adiantum), requires a more alkaline soil.
Correspondingly, can I use succulent soil for other plants?
The cactus soil is usually dry and mimics the environment of the cactus, that being dry and with inadequate nutrients. This soil type may work for other succulents and indoor plants that do not require water and moisture. Plants like these have shallow and fragile roots, so they do not need moist soil all the time.
In respect to this, how do you prepare soil for ferns?
Most ferns prefer the soil media to be moist without being sopping wet or completely dry. When preparing a well-drained media of perlite, bark and peat moss, the goal is to encourage even aeration and moisture retention between each watering.
