I've rooted multiflora in both soil and water, and I've had success with both methods. Several months ago (before it got so cold!) I rooted a few cuttings in water, and they developed roots very fast. But I put another cutting in water maybe a month ago, and it still hasn't developed roots. But it still looks healthy, so I wouldn't worry as long as it still looks healthy. However, 4-5 months is a pretty long time, so I don't know why it hasn't developed roots yet. I don't think there is anything you can do now except hope for the best. Have you been changing the water every few days or at least once a week?

Keep it in water. 100% success, although Multiflora is the slowest of any hoya to root for me. If it is green it will root, just be patient.

However, 4 months is longer than it has ever taken me. You probably can look at the cut with a magnifier and see 6 or 8 white circles which will be the roots. Multiflora roots are anything but fragile like most other hoyas, which is probably one of the reasons they take longer to root.

Years ago, I read that when you're rooting Hoyas, they root better in colored glass - I think it said it had something to do with the light on the roots. So, when I root Hoyas in water, I fill a container with small aquarium gravel. I have all kinds of pretty containers like candle holders, wine glasses, etc. I do this with... It seems like they root fast and the roots are stronger because they have something to "grab" onto. The water evaporates fairly quickly, so I'm typcially topping it off every day or two. You might give that a try.

I've had success with rooting various plants in water that are known to be difficult when I kept the water warm. I used to keep them on top of a refrigerator that was always warm, even used that spot to start seed trays.

Sorry, no suggestion for the poster here.

Hey Denise,

Happy New Year (I did answer yr. EM, hope you got it).

Interesting abt the colored glass, have you discovered if some colors of glass work better than others? That's be a curious thing! I'll have to keep an eye for colored glass, I tend to use clear plastic cups for water rooting cuttings so far.

Hope to buy some new Hoyas in Spring, I'll have to experiment!

Hi Karen,

Got your EM - and Happy New Year back at ya!

I wish I could remember where I read this little tidbit - I really don't remember if it specified a color, but my experience has been that they root fastest in brown glass, probably because it blocks more light than other colors. But a few years ago, I seem to recall reading a post from someone who said they found plants rooted faster in green water (water that had not been changed and formed algae...) and wondered if it was the COLOR or the ALGAE.

I started using the fine aquarium gravel a couple years ago with long cuttings that wanted to fall out of the glass, just to hold them in. I found the roots formed quickly and were more like soil roots, I assume because they have something to "grab" onto. I also root quite a bit in moist perlite. I have a couple old silverware strainers (you know - the kind that come with those wire dish draining sets) out in my GH filled with perlite. They hang nicely on my wire shelves. I water them (they have the holes in the bottom, of course...) and stick lots of cuttings in them, then mist them every day. Those seem to root cuttings quickly, too.

I keep trying that baggie method I've seen talked about and that has never worked for me! Guess every environment is different!

I would try root a cutting in soil with a heat pad under it to see if things will speed up. After 4 months of trying to root and then rooting in winter certainly have disadvantage.

Hm... some good suggestions. I think i might try putting it into some moilt perlite on top of my fridge. I have a tray of baby violets up there and they all do very well. Maybe my hoya babies will like that spot too:)

Hope everyone is enjoying the new year so far! I cant wait for spring to find a few more hoyas. I have some chinese clivia seeds on the way now. Im pretty excited about that, they are my other passion. I pollinated my old clivia this year and I actually have a berry growing! Yay!
