My tip is that I mix a sprinkle of cinnamon into the new potting soil. It helps prevent infection from starting while adding a small bit of natural fertilizer.
Taking shorter cuttings makes it much easier for the roots to grow and provide nutrients to the rest of the cutting. I stick them into a combination of potting soil, orchid bark, and some worm castings. This is the same type of soil that the plant itself is in. I have also found that because these plants, in their original form, grow in the crooks of trees they therefore love the bark. The shorter cutting, of maybe three to four segments, very fast and stays plump. Keep the soil moist but do not soak it. I have rooted cuttings that came right off the plant and also cuttings that have sat for a day or two. It works either way as long as the cutting doesn’t get dehydrated.
Interesting! I looked for a follow up on the cuttings in water in your videos after this one. But I could not find any, at least not from the titles and the thumbnail photos for the videos. So I am wondering how did those large cuttings in the jar with water do ? I'm thinking of those in the jar with the poppies painted on it...
I'm trying to root Thanksgiving Cactus cuttings (with node) in water, gravel & perlite as you described in this video. After 10 weeks or so I'm not getting significant root development ?? I keep the water level at the perlite.
As long as the cuttings look healthy then just let it keep on going. Some varieties can take longer than others. Time of year, how much light they get, all can play a part.
Sorry, check out the blog post for close up photos: www.flowerpatchfarmhouse.com/root-christmas-cactus-plant/ and I also show a close-up in my previous video at 1:33 : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6q4wjOFj9So.html
