You can grow it in a small pot until you see the roots coming out of the drainage holes. There is a way to trim the root ball to keep your plants in a smaller pot but I'll let someone else give you instructions for that.

The big box stores (Lowe's, HD, Wal-Mart etc) usually have the easy grow hoyas.

I have hoyas in 6 inch pots for over 20 years, bloom like crazy and do good. The soil is nothing but a mass of roots. I think hoyas like to be root bound.

The smallest Hoya I know is "curtisii"
you can see my hoya curtisii and pot in link below.
Thanks.

i have a carnosa, quite large (shes not a giant...yet) in a tiny 4in pot. She has to be 7+ yrs and does just fine, blooms constantly, and hasn't complained yet. I always feel bad every spring when im doing the repotting on everything else but the hoyas...then i look over at this one and cant bear to repot her. Too happy, too many blooms, too hard to wait for her to fill a new pot with roots and wait for blooms. With the hoyas i wait till they look stressed or absolutely need the repot before doing it:) Ive also started putting cuttings in this size to get to pot-bound quickly. they seem to like this.

Just yesterday I was at the Sacramento Cactus and Succulent show,
and I saw a Hoya carnosa that was trained up a tall and narrow hoop, about two feet tall.
The plant was growing in a bonsai pot, maybe eight inches wide and two inches deep.
I should have taken a picture.

Oh Josh...why didn't you? I would love to have seen a hoya in a bonsai pot! Darn...

How small of a pot are you thinking? 2"? 4"?

There are several small-leafed Hoyas (serpens, curtsii, picta, heuschkeliana (pink), panchoi, pubera) but they all... expand. Curtsii is a good example of one that seems to grow like a tiny demon.

Carnosa is tolerant, so it probably won't die on you even in a small pot, but I don't know how you will keep it small other than to keep chopping off the vines. My sister had one in a 4" pot, growing up, and it just climbed the entire length of her room. Much like Josh's example, (which I would also have liked to see!) the POT was small, but the PLANT was not.

My mother has several very old blooming carnosas that she keeps quite small. I have to assume she prunes them. They're in pretty low light, too.

Hello!
I know, Nancy, I really should have taken a pic! What was I thinking?! ;-)
Keith (Caudex1) had many, many plants on display, and he took lots of photos....so I thought I'd check his
uploads to see if he happened to get a pic of the Hoya. Sure enough, you can see it in the extreme right side
of the pic I've linked below. All credit to Caudex1. What a lifesaver!

Thanks for tracking that down for us, Josh! Next assignment: score us an interview with the grower. jk ^_~

Wow! Beautiful plants one and all.

Susan

Oh Wow!! Thanks for the detective work Josh...that is a beautiful Hoya bonsai! I must say that's the first one I've ever seen! Thanks for posting! Glad Caudex had the picture.

Hi everyone:
In my blog there is a possible "hoya bonsai". He was not my intention.
It may be a cutting of red button. I do not remember now.

You can see link below, "bonsai involuntario".
Thanks
