An update on how mine are doing:
The tip wilted off the far one, so I thought it was dying, but another is growing to take it's place.
The near one is looking ok, but still frail. I just put up the netting and trained it a bit.
They've been cut from the main root system for a month and they're still alive, so I guess I'm doing something right.
