@Strtrki, I have never tried rooting in water, so I certainly know nothing about rooting that way. Perhaps others will know how that works. But since you still have cuttings after all this time, unrooted cuttings, I would tell you to indeed use another method to root.
Wow, you have cuttings that have been in water for 10 mo., and they haven't rotted or rooted. That's just amazing. I've stored cuttings in a warm and dry spot for several months, but nothing like 10 mo.
If these two cuttings were mine, I surely would remove them from that water. I assume the ends are callused, but again, having them in water all that time, I don't even know that. Are the stems still firm, from the cut end all the way to the terminal end? Is the color of the stems still green? If so, the way I now root is with potting soil, but soil that is heavy in super coarse perlite. I now allow all my rooting media to get rain, and since this is the rainy season in S. Florida, my cuttings pretty much stay in moist potting soil. I used to root in dry super coarse perlite and nothing else. I've found that rooting them the way I now do, cuttings root far more quickly than in a dry media.
I would love to see a few photos of those plants, clear photos showing the cut-ends, the stems, and the leaf ends.
I sent you a T-Mail.
