Outstanding info that I wasn't aware of. We must do everything we can to protect out buzzy buddies.

I think they're less sensitive after that first round. Good luck!
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.
That's my name! Am I a plant?
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.
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.
But then you'd be a premium user and in a demographic even more likely to spend money so you'd get "catered purchase opportunities" from advertisers that paid even more for your special eyes...
