Hi Dill786,
Most probably the climate was too hot then. So the cuttings did not have enough time to take root and start taking up moisture. My advice is that if you ever have the opportunity to have cuttings again think early spring or early autumn. Check my previous post above. You planted the cuttings in mid-June then you a heatwave with temperatures in he 30's. That is what killed off any chance of the cuttings to take root. March/April or Mid Sept/Mid October are the best seasons. Obviously the type of cuttings would be different according to the season. Using seeds is even trickier as you pointed out. That is why I am looking for cuttings.
Have been looking for this plant for years as well. Are you really sure it's possible to root them without any leaves at all?? Seems very counterintuitive because the cutting has no way to get any additional energy apart from the energy stored in the cells of the cutting to grow roots and new leaves. The last time I got a cutting to root I left a leaf on it and kept it in a baggy and under CFL light. Temperature was probably around 25°C throughout. Haven't been able to do it again since this first lucky strike though.
Neither seeds nor cuttings anywhere to be found on the net, it's a pain.
you gotta germinate the seeds straight away though,,, mine didnt germinate coz they were in transit for too long.....
the person who sent me the jade vine rooted his cuttings without the leaves and he said he had good success...
Heya, I know I'm necroing a thread like crazy, but I stumbled across this post and found a ton of great information, so I wanted to try to give back.
I have three small jade vine plants that I'm currently growing. They're still quite young, but VERY healthy, especially now that they're in a humidity and temperature-controlled greenhouse I built on my porch. I can't do cuttings quite yet, and I won't get seeds anytime soon, but as soon as it's big enough I'll be sure to post here to let anyone interested in getting their hands on one know.
