I pot up when roots are coming out of holes. I move mine to the bottom shelf on my misting system for 1 week, then move them out. The bottom of my sytem just gets sporadic misting, since no misters are located there.

I too tried the misting system suggested by many at this site with much success so far!!! 3 weeks into the process have 45 clippings with leaves sprouting from the twigs - checked for roots today - none yet. Have 5 clippings per clear plastic pot. When do I move to soil and do I continue to mist at that point?

mgleason, Thanks for your response. Potting up when the roots poke out certainly makes good sense, otherwise the little guys would be vulnerable to damage. Putting the potted up plants on a shelf underneath the system won't work for my set up, but i can have them to the side where they will receive sporadic misting.

michela, Yes, this is exciting. I thought 'Oklahoma' was fast--taking only 3 weeks to root, and then 'La Tosca' took only 17 days!! I have only one cutting per container so it's really easy to move them. When potting up I use a lightweight potting mix I make up of a commercial mix (one without added fertilizer) with pine bark fines and perlite added. mgleason seems to have the answer to your questions as they are much the same as mine.
