I have a question, I have the den aggeratum and I live in a very arid, dry area of the US, Denver. Do you think I should water mine a bit during the rest? Is a cool window helpful? How much sun?
I don't grow this one, but generally "winter rest" doesn't mean no water, but greatly reduced water and no fert.
Hopefully others can advise more specifically - you may want to start a new thread. Good luck
