Bretton, I'd also like to know how this turns out. Keep us posted. I know this can be a very intimidating process. Until recently I'd never done it...I mean...Grow a living tree from a twig. There's a lot of wisdom on this forum, and everyone is genuine. A really good membership.
You do seem spot on..... And so are many others - from cloners to those who swear by, "stick a twig in the ground and wait". There is more than one way to do this so just because someone is doing something a bit differently, doesn't mean you should give up what you're doing.
If I could make two suggestions based on my personal experience, first would be that you consider rooting more than one cutting at a time. The reality is that I've never heard of a grand master fig-er who is 100% successful. I'd recommend getting yourself a number of cuttings. Some will take and some won't. This will also allow you to assess what you might have done differently with the ones that made it versus the ones that didn't. Cutting size, number of nodes above and below soil, water, light etc. It's from that process that we all learn and share.
Second suggestion is the difficult one. Be patient. I know it's hard when you're looking every day for a sign of roots but it can take time. I know some see roots inside 2 weeks. Myself just yesterday I saw the first sign of actual roots from a cutting I started first week in September. Others in the same batch don't look dead, but still have yet to show me anything...
I look forward to hearing of your first fig...
