1) I don't acutally know the person in brazil that has the sarrs, I just read about him and saw his plants on the CP listserv.
2) I've only had the sarrs for a year i think, but they did go into a dormant state last year around December. They did this without any help from me... I think it was the shortened day-length that did the trick.
I'm hoping that my plants will do the same thing again this year.
