Pete,
I'm going to start calling you JR.
Life is full of disappointments, and this includes failing to root fig cuttings.
I too lost a few very rare and very hard to get cuttings.
But I look at the bright side. I compare the loss to the success, and the success far out weighs the loss. To make more sense, If you succeed with 3 or 4 variants to every one lost then in my opinion you are coming out ahead. Look foreword to next season, because next season you will be better prepared and more experienced.
Another thing I've learned is that young and newly rooted figs/cuttings don't like to be moved. I have had some looking perfect and once I moved them to a new location it's like they went down in a heartbeat. So try to be a just bit more patient next time when re-potting. I have had a couple more ones sitting in their original long pots till today. I just placed them in 1gl.pots earlier and put them right back to the spot they were. Point is, I waited this long to re-pot them for a couple of reasons.
Good luck
