I think it's probably just stupid.

Just kidding! I missed you, Kim, that's my bratty little kindergarten side coming out. ;)

And I can't get my Hoyas to bloom without blasting to save my life, so yeah, they're stupid.

I just laughed so hard at this. Some plants are just stupid, for reals!!

Tawny, I laughed. No worries. ;-) It is stupid. Seriously, my mom grew this under conditions that would make a proper horticulturist cringe. Plant grew like crazy for her, and always had blooms. Will keep at it, she says all she did extra was mist.... we will see. At least my H. javanica is about to bloom again for me, I have ONE hoya that isn't stupid.

I increased the dosage on my foliar feedings, and am misting every day. Currently, we have 6 adorable little bundles of disappointment. At least my African violets are blooming. That, and my awesome H. javanica looks like it will have some blooms on it again any day now. That javanica might be the easiest to bloom Hoya on the planet. At least, that I have grown.

Bumping this because my bella has started doing the same thing :( The buds get almost to full grown and start blasting. I'm thinking water more? water less?

Bella is a cool temp. growing hoya, so make sure it isn't exposed to high or dry heat. I never could get this one to be happy for me, but I have it's tiny leaved cousin (chinghungensis) growing and thriving, hanging under the skylight in my kids' bathroom.

Bella (and chinghungensis) likes to be kept lightly damp, but not drippy/soggy. Growing semi-hydro seems to work well, but I make the reservoir shallower (1/2-3/4 inch for bella/chinghungensis vs. the standard 1-1 and 1/2 inch reservoir for other hoyas) because the roots seem more shallow and more sensitive to growing in the water. This is probably a defense mechanism due to them being cooler climate growers.

Ahh.. that could be it. She is thriving here because it's colder but we are having a bit of a heat wave at the moment, maybe that's upsetting her enough to start dropping buds.
