Cold period to stimulate growth?
I have a cutting that I have rooted from a ornamental "prunus" bush. The cutting had a hard time, but it did establish some good roots. I took the cutting as a semihardwood tip cutting in mid summer just as the growth was slowing down. The cutting did not ever produce new growth this year. It has just recently dropped the 2 leaves that I left on the cutting. It looks like it has some buds that are set to hopefully send out new growth.
However, I was wondering if the cutting needs a dormancy period to begin new growth. Does the cutting need lower temperatures to induce that dormancy? Or, will the daylight hours getting longer alone stimulate the plant to begin growing? (The cutting has been indoors the whole time, and is currently in a west facing window)
