This is a tricky one, with no "right" answer. I used to do all my rooting in water, for some plants I still prefer this. Thanks to some good advice here, I have started rooting in perlite. Stuff isn't ideal in that it floats, but I tend to get some pretty massive root systems in a shorter amount of time with it. Apparently, the water grown roots are not as strong as roots grown in other media, so a lot of people prefer to skip that step and root directly in soil. I personally still have issues with not being able to see what is happening, and have been experimenting and had good luck with most of what I had tried but those so far have all been with non Hoyas. I am sticking to perlite, at least until I use up this bag. With that said, I do have a cutting of Bella going in water, which is how I have always rooted this one. Either way, it should do ok.

Well this was not exactly intentional. Yes i knew hoya could root in water (the mother plant may have been, but thats not exactly the plant in subject) but i thought i had more time... i guess it really likes my desk at work, i thought it was too cold. after all i have a sprig of pothos in the same jar that while it hasn't died also hasn't rooted. i was thinking about getting a grow stone or such and rooting it in a new medium.

thank you but is there any tips or things i should look out for if i try to change mediums? or should i just leave it in the water? if the pothos roots will the two be bad for each other? is it true hoya can take in nutrients through leaves?

H. carnosa is pretty tough, I wouldn't worry about transferring it. It is highly unlikely you will upset anything. I have transferred from water to perlite, then knocked said cutting off my window sill 6+ times and still got decent root systems and plants that happily transitioned with a couple others. Besides, sooner or later it will need to be moved anyways. I would keep treating it as a cutting if it just has a baby root system, just until it really gets going.

Ty.. should I add rooting powder to the water?

I usually do, though it isn't always necessary. May as well if you have some on hand!

I can bring some to work on mon... though it might make the pothos root as well

You could Hormex that has a rooting hormone and Vitamin B1 and is liquid, so it helps when water rooting. Also very good to use with any seed starting or rooting in other media than water. Just water the media used and it does its magic :)

Stacy, just saw your other two questions. I am not sure if pothos and Hoya would interact negatively, but I don't think so. The roots may grow tangled however. And also yes, Hoyas can take in nutrients through their leaves. I mist mine with a diluted kelp and willow extract based fertilizer called Tappin' Roots, they seem to like it!

Cool i'll try to keep them from tangling. everyone in the office grows pothos it will be nice to have some more elegance -smirk-
