Growing Xerophytic (Arid-Loving) Ferns
By Dave Seigler

Most of them aren't easy to grow. A light mix with lots of peat moss works
for many of them. But apparently they are very sensitive to edaphic
conditions and some may require high light. I was never able to keep most
of them going for more than a couple of years. The spores of many will
germinate readily when sprinkled on inverted flower pots stuffed full of
peat moss and placed into petri dish bottoms and covered with a beaker.
Quite a few will even produce sporophytes that can be transferred into pots.
Mr. Knipfer at the U. of Texas greenhouse recommended the following mixture
for potting soil. It works about as well as anything I've found: 7 parts
sand, 12 parts peat moss, 3 parts perlite, 4 parts vermiculite, and 1/4 part
bone meal. But all in all, except for a few of the most common species, I'd
recommend that people not dig these up and try to grow them ... unless they
have some reason to do so. Unless methods for long term cultivation are
perfected, most are difficult to grow and many are found in only limited
populations and may be endangered or threatened.
Hope this helps, regards,
