I am afraid of breaking their roots with manipulation, so what I do, is I put the fat cuttings to root and when they show that initial eye (white dots) I graft the new variety and keep everything in the warm chamber newspaper lined with a little moss so I can see what they are doing without much touching them... they look amazing, pushing roots and graft heals at the same time, I notice that it is even better, if the cutting also pushes a bud, as it works as a nursing branch for the new graft. I lost a few to gnats and sadly, the roots were eaten but the graft union was well bonded. So, I have other set of problems. It has been really bad here for gnats I am working on my garden and they are eating everything I plant... gosh I hate them... Not sure there will be garden this year.
