Ive been growing Cielo for a few years and haven't had much success propagating it, using ringworms technique or my own. What I have found to work every time tho, is to simple bend down one of your vine shoots and bury a node in a pot, keeping it connected to the plant until enough roots form. I have been able to clone some branches by plucking them straight into the growing medium and placing them in a humid dome. For the latter technique, it seems as if the semi hardwood shoots work the best, as opposed to young green shoots are woody ones. I think by taking a more woody shoot, and placing it in a glass of water for a week, allowing the bark to soften a little before placing it in the soil , may help it to form roots. Ive also had success by just putting shoots in a glass of water and letting them sit for a month, but maybe only 10%, or 5 of the shoots ive tried. Its still hit or miss for me. I'm still after a more proven technique and am open to any suggestions.
