Blackening of cane tips while attempting to start cuttings
I've been a successful failure at propigating Fortuniana for a year now and would realy like some help.
I've used the 2ltr cola bottle as well as the clear baggy technique. I've even tried growing cuttings in those Jiffy Pot seed starter kits (the ones that come with a clear plastic lid) with no success. All of my cuttings turn black, starting with the tip, and rot away.
What am I doing wrong? What can I do to correct my error?
Thanks in advance for those of you that have read this far.
