I have a S. leucophylla 'tarnok' that has been growing in a terrarium for about a year and a half now. It is about 14 -16 inches tall. I haven't been able to get to it because there were too many thing in front of the terrarium but now things have been rearranged so I can work in it. It gets full sun for about six hours and the temps range from 55 at night to around 85 in the day with 75-80% humidity.
My Question is, What is the best way I can bring this plant into dormancy this late in the season? Just bagging it up and sticking into the frig doesn't seem like a good idea to me.
Anyone have any suggestions?
