I'd like to pass on to everyone the method I use to keep clones (cuttings).

I use a pint size mason jar, and put about 1/2" of water in it. Place cuttings in jar with cut end in water. Pint jar will hold up to abt 60 cuttings.
I vacum seal jar (1/30th atmosphere if your vacum sealer has settings, seems to work best for me) then I place jars in a cardboard box, then into the refrigerator.

I have had great results at 90 days. I have a batch I will check soon when they reach 6 months old and we'll see how it goes when I propagate them.
