Night flowering jasmine is not a true jasmine, it's actually Cestrum nocturnum which is in the nightshade family along with tobacco and tomatoes and a bunch of other plants, but being a science teacher I bet you knew that already, right? (WOW! That was a long sentence wasn't it?)From what you tell me it appears as though it is getting enough sun, my concern is your fertilization. Fertilizers that are high in nitrogen promote excessive vegetative growth at the expense of flowers especially in the nightshade family. It sounds as though in general you may be overfertilizing. I don't know how frequently you are fertilizing now but I would hold off feeding your jasmine for at least a couple of months which might help stimulate bloom. Some plants just bloom better on "leaner" soils. Cestrum nocturnum usually blooms in cycles throughout the year so flowers could pop up just about any time. Again, if your plant is healthy then there is no reason to worry about the low humidity and light. If your geraniums and lavender are blooming then there is sufficient light for your cestrum to bloom as well. An interesting note, about six months ago I acquired a small cutting of Cestrum nocturnum, it never bloomed and never really grew much either. Eventually it died and I threw it in the trash. Come to think of it, I guess that doesn't make me much of an expert on night blooming jasmine, does it? Maybe I should be asking YOU for advice! :-)thats it!!!
