Your rooting ideas intrigue me. I may just give that a try this fall/winter when I can no longer ship and things begin to slow down, go dormant. That being said, if commercial growers are beginning to root them en masse, I may not have a viable market for them in the future. So far, I have never seen a fiddleleaf sold in anything but a high-end garden nursery, and extremely seldom even then. If they begin showing up in big box stores outside of S. Florida, I know the days of my shipping them will pretty much be over.
I am so sorry the fiddleleafs did not make it. I still have one with a chance but the rest are kaput. I always have believed that one learns more from his mistakes than he does from his successes, so we will just label this a "learning experience" and move on. Ken
