The prime reference book on tree ferns is "Tree Ferns" by Large and Braggins. Though an excellent technical book on the type I would say, Not for the Beginner/not what you're looking for. I consider the "Fern Growers Manual" revised, by Barbra Hoshizaki, as a top quality, user friendly resource.

There aren't any books dedicated specifically to growing tree ferns - just brief passages concerning cultivation in various more general fern books. Even that Fern Growers Manual from Oregon publishers Timber Press, mentioned by Pat, is pretty frustrating when it comes to tree fern coverage. The best general cultivation chapter I know is in The Plantfinder's Guide To Garden Ferns, by Martin Rickard - Timber Press again. It's a strange gap in the market in some ways, especially considering the recent growth in interest in garden tree ferns, but it's unlikely that mainstream publishing will ever furnish the hobby with the right kind of specialist book - it's too marginal to make economic sense and times are very tough indeed right now for niche publishers.

To be honest, you'll get more from the internet - there are a host of intriguing online sources dispensing tree fern advice, wisdom and controversy. Fire up Google and try and track down Keith's Fern Pages (an Australian viewpoint); the Fernhouse (a New Zealand perspective on the tree fern hobby); Cold Hardy Tree Ferns (a US overview)...plus consider joining the international forum called Growing On The Edge, where there is the biggest aggregation of tree fern enthusiasts anywhere on the internet. Ask any manner of tree fern related question there and you'll get virtually instant words and photos back in reply - Dicksonia, Cyathea, Cibotium, indoors or outside, in the garden or in habitat!

Marcy, I'll leave you to enjoy researching those links I provided in the previous post. But one thing that is worth stressing is that all tree ferns, to a greater or lesser degree, are high moisture dependent plants that require a permanently damp environment to thrive. If you're growing indoors in a sun room, that will dictate serious shading and possibly even humidification if your temperatures are high. Not everybody has the means or the inclination to go to those lengths if their ambient climate is not already at that end of the spectrum - life is particularly challenging in cold or desert-dry conditions, for example. Even so, anything's possible if you want to do it enough!

As usual, Stephen has provide superior information. Excellent idea to work the net for info, esp. Keith's from OZ. Stephen's tip on moisture is right on the mark. Most still require good drainage. I might add, don't go for "cheap" potting mix. I've learned my lesson the hard way. Make your own or buy the best, then modify as needed.

Why not also try the-Cold hardy tree ferns page-quite an excellent site,
although possibly a difficult(with out a laptop)choice
for a bathroom read.
