Dug, that is so good to hear! I rooted mine last year like I do with figs.. well, like my figs, I ended up with just one growing. it had beautiful branching, but it got too cold and it is starting the process of branching again, believe it is an Illinois.
I got more cuttings this year, but need to learn more to improve my chances. I have a couple I got from Richard Watts and those are neither dead or alive. I have them in potting soil mix inside of a soda pop mini greenhouse. on warmer days, I put the bottle out there under the tomato plants in my cold frame, but bring it inside every night. It is just a stick showing a few bumps, so, they may turn into roots...but it has been more than two months.. .
I read somewhere that they need cool top and warm bottoms, so, using a heating matt outdoors? Not sure how to make the top cool and bottom warm.
