Leptotes unicolorThis is the most frustrating thing ever… My Leptotes unicolor is setting bud after bud that inevitably blasts (shrivels up and dies) before maturing to flower. I have watched at least 4 buds go the past few weeks and there is currently a new bud on the way. It is at the critical stage when all the previous ones have failed and I am desperately trying to figure out what to do!

I have doubled the watering, misting it thoroughly morning and night (on top of the weekly bath). RH hovers between 85-99%. But I am not convinced water is the problem. Perhaps it is too warm in the vivarium? I read conflicting culture advice for Leptotes on the internet. Some say to grow this species cool to intermediate, others say hot to cool. Mine hangs in the warm vivarium, but it has not been very warm in there lately, only reaching 24 degrees during the day and down to 15 degrees at night for the past month or two.  My Leptotes bicolor bloomed in the same vivarium this spring when it was much warmer, but I got that plant in bud and perhaps the buds were past the critical stage then? I have got to figure out what to do! …more research… 

PS! I wonder what the freeloaders’ name is? (The tropical weed that shares the mount.)
