Can I air layer an old Cordyline?
I have a cordyline australis (I think) that is 30 years old and has been living happily in a large pot. It now has a trunk about 10 feet tall with a rather daft looking tuft of a dozen leaves on the top and no shoots. I'm loath to get rid of it, so I'm wondering if I could try air layering near the top of the stem to create a shorter plant - or is that a silly idea? I know, I know, I can easily buy a new one, but this has sentimental value. All suggestions welcome!
