Just follow the "tenting" advice that Griff published. I modified it for my purposes. He has a re-bloomer called "Autumn Nectar" that he says rivals "Over & Over", "Immortality", and "Again & Again". I just got it so I can't say how it performs. I am going to have to plan on tenting in the future and get more to bloom this time of year. This was my first bloom ever for "Haunting", which is why I went to great lengths to get it to bloom.
