Hey Keiko. Congratulations on your cuttings! Do you have any further details on which rigida you've got there? The cuttings look great!! I don't have much time so I'm going to make this short. But I wanted to post quick in case you're still reading tonight. Yes, you need a node to be at least at the surface level of the medium. It doesn't have to be completely buried but it needs to be in contact with the medium. If there's too much stem underneath the node you can trim it, or just sort of bend it in the pot, or even lay the portion that is above surface level horizontally along the soil, weighting it with stones. Anything to provide node contact. Although un-useful to you, it isn't very unusual to receive a long segment underneath the node. It's because when the grower is harvesting the cuttings, they make their cut right above a node, b/c anything vine stub above it is going to die off anyway. So you get that segment, however long it is. Good luck and happy rooting! :) And to answer your question, I usually root mine right in the medium I plan to use long-term. But for valuable or delicate cuttings, I often root them semi-hydro style. When possible, I like to lay multiple nodes along the surface. Otherwise I'll cut the cutting up into smaller segments and root several starts. Really, I don't have a system I stick to every time. I just use my gut and do what feels right for that particular cutting. :) I like to experiment and test theories with every batch. Also, I tend to use a rooting aquarium or even a clear tupperware bin, to provide extra humidity, but I don't like the bag method because I screwed it up once (by putting the plants next to a bright window and baking them) and have bad associations with the innocent bags. This time of year though, I don't bother. Hoyas like to root right now. I have a few re-rooting at the moment and I just stuck them in the soil. They'd better root >:O Whoa this didn't turn out short. But it was fast! So if I said anything crazy, just ignore it. Bye!

The Basic method of choice for me is (1) Take a tip cutting of firm new growth (2) remove all leaves but 1 tip leaf (3) If that leaf is large cut in in half(4) apply a rooting hormone of adequate strength. (for the plants you have named us 0.1% IBA) (5) stick in well drained soil & Mist several times a day (6) keep plant out of direct sun & have indirect lighting (7) avoid strong draft but the air should ciuculate freely around the cuttings. usiong this general method I have 80-100% rooting on almost all plants......... Enjoy the fruits of your labeo :)

It will work as well but you will have to change pots a bit sooner to something with soil to feed the new plant. This method is all about lessening the amount of times you have to disturb the roots. I feel like with the baggy and moss method you add one more unnecessary step. Each time you transplant the cutting with such delicate roots you run the risk of damaging it. Which increases your chances of failure.

I definitely went with pre-rooted to start my collection, with 1 gifted cutting that I'm trying to root, and some seeds to play with. Because of this I've gotten to enjoy many blooms already, in only 2 weeks, where if I get any seeds to grow it will be 2-3 years, and I'd assume the cuttings that make it could take some time. But then, I have no green thumb, so this was a safe way to start.
