Outstanding info that I wasn't aware of. We must do everything we can to protect out buzzy buddies.
The first blooms on a peduncle frequently blast. I had that happen on my carnosa, one little flower made it...
I used to, now I have so many that's it's enough work to remember the species names.
Hoyas like to wait. People say they like to be root bound, I think they just like to be unbothered for a long time. I said the same thing a year ago and now I have three that bloom regularly. My lacunosa has bloomed a week a month for the past 4 months.
You should be able to get elemental sulfur. Even if it's not labeled a horticultural product, so long as it's 100% sulfur you're good to go.
My Hoya ilagiorum bloomed!
Perfume is a bit fainter than my other Hoya but Inigo makes up for it with pretty blooms.
It's weird, right? Cheap and effective.
I think if you rinse you must repeat but leaving it on works too.
It pretty much kills the mites dead on contact, so I did everything once I understood the problem and all new plants will be doused, but unless I see mites on anything in the future I might make it an every coupla years thing. A few of my friends and I have a theory that sulfur is an important micronutrient for Hoya as we see bursts of growth on even plants that didn't have mites.
Well that's deeply unfortunate.
If you have hoya, seriously consider dousing them with sulfur for flat mite control.
Flat mites are becoming super common in the Hoya world, but because they're so hard to see and do damage so slowly most people don't know about them. A lot of cases of plants failing to thrive, never growing, or just looking sickly and slowly dying may be due to flat mites. You can see them easily with a cheap handheld magnifier, usually on the underside of leaves near the base.

To cut to the chase, mix 2 tbs of sulfur with a gallon of water, shake vigorously, and put it in your sprayer. Shake frequently while spraying. Do it outside, we call it farting on our plants for a reason...
The gracilis (memoria?) pictured looked OK but it was next to patient zero, a fitchii that is just now coming back from the brink of death. The gracilis is suddenly growing like mad a month after farting. I left the sulfur residue on the leaves as a preventative so you can easily tell the new growth from old.
Bit of this, bit of that. Mostly Hoya but I have some carnies for gnat control.
If you leave them on the plant they do the coolest thing - eventually they dry out and pop poen and fling seeds several feet.
