some hoyas never seem to bloom and others have no trouble?
Does anyone know why....
I think that question is on every Hoya collectors mind and nobody seems to know their secret LOL.
The general required condition for flowering seems to be warmth, constant soil moisture and high humidity and from there on it they only seem to flower when they feel like it Haha.
Some species like bella or multiflora may flower while still a small cutting but are prone to "bud blast" and are finicky with soil moisture (lots of water).
H. carnosa and H. compacta flower profusely once they got started but it may take several years for them to start.
Hoyas from the Erisotemma group like H. affinis are very finicky and may never flower if their ideal conditions are not met.
So my recommendation would be keep them warm and humid, water well and do not let the soil dry out completely and try using a bloom booster fertilizer to give them a little slap on their plantly behind.

When I was a kid my father had a row of hostas in old pots down at the back of the yard by the chicken house. When I say old, I mean old - they were more broken than whole and the roots were all exposed and he often forgot to water them - and they flowered all the time!!!
When I got my first hosta I put it in a nice big pot with lots of soil and watered it, and it looked beautiful, but it never flowered.
So... I moved it to a tiny pot where it is always rootbound and only water it once a week, and it is just covered in flowers every spring.
Hi JoanR.
Do you mean Hoyas or Hostas?
I meant Hoyas. I guess my brain stopped functioning when I wrote Hostas. It does that you know, as your age increases!
