RE: jade fern

Gary, I'm far from an expert on ferns and I've never heard of this one, but a lot of the ones we have in our garden are deciduous or semi-deciduous, the leaf-fall generally coinciding with either the dry season or the period after they produce the spores. There's a technical name for this but sei la.. What I do with them when they start to look ratty is cut the bad leaves back to the rhizome and then just wait from them to revive. They're pretty tough and hard to kill so don't be frightened to wield the knife. Good luck. - Ian.

RE: jade fern

This fern is native to the lowland rainforest of Thailand. have had no trouble growing it grow just that it is spreading rather than growing up. Have heard it will get over 18 inches but it topped at less than twelve.
my main conplaint is that it has turned a dark green losing its irridescent blue color. it is a "Reverse"
synthisizer ,utilizing reflected light so it can grow in very dark forests. A person that I found on the web who is GH growing says that it's an "obligate limestone lithophyte" Growing has NOT been a problem just the habit??
I've transplanted to a clay pot with long sphagnum and placed it near my shade marsh garden . So far it's reacted by spreading further and staying dark green lol
Many members of this genus are aquatic or amphibious but so far have Not been brave enough to put in water lol
Got to be the worlds most beautiful fern,when happy lol Thanks gary

I'm just guessing here, but it sounds like a "limestone lithopyte" would like alkaline soil.

RE: jade fern

i transferred it to a 6 inch clay pot with long fibered sphag. placed it along the edge of my marsh garden. Has started to respond with MUCH taller fronds but still lack the colors but can see I'm on the right track Going to try this with the Elaphoglossum ferns which are suffering from the same problems..
steiconi i doubt that either are "limestone lithophytes" though they certainly may grow that way in the wild and that condition is very tough to dublicate particularly in a temperate garden!! wasa unable to find habitat pix of either but i did find they are definitely NOT high altitude so I have a chance though the first is from Thailand the latter from Peru lol
They both occur in very low light high rainfall areas
but not montane rainforest. Thanks gary
