Soon to be dividing a very large and heavy one that I have had for ten years. So I am considering devising some type of box type frame of non corrosive material for long term mounting and hanging in trees that I can easily move in and out for winter. Some I'll mount on wood like the article and give away, but since I've enjoyed the outside hanging one and the conversation piece it is, I want two for long term growth.
The one I have grew to be a 80-100 pound monster which encased the original wire basket the past ten years. The wire has now rusted, and the chains attached are in danger of breaking. In winter I have to move it every fall into the garage, so the weight is an issue. I plan on dividing it this year, and the problem will be cutting through the old wire when I divide it.
With the fan cover idea, like my wire basket, the new fronds will grow through and cover the wire frame. If it is not stainless or aluminum, you might face the same rust problem I have in time threatening your hanging support.
For my next outdoor hanging specimen, I am considering some type of heavy duty non rusting hanging box cage type frame. Will fasten some of my divisions inside the frame structure and just let it grow outward. I won't have to worry about rust, hanging chains, etc., and future plant division will be easier. In my experience, it is best to have a 3-4 chain support for balance and leveling since they will tend to grow lopsided over time.
Will post an image of one when I build it later this spring. Thinking about an 8-12 inch wide box frame of aluminum or stainless should suffice since I want the fern to encapsulate the frame in a few years, with eye hooks on the corners to easily adjust and secure the chains.
