@Miamiu, Please share your rooting in water procedures. I usually experience only necrosis when I attempt to root in water, but perhaps one or more of your protocols may help me out. When you root in water how long are your cuttings and how many leaf nodes do you tend to submerge? Do you strip off or keep most leaves above the water line? Do you pinch the newest growth at the tip? How often do you change the water? Is the water kept at room temperature? Any bottom heat? And finally, are your cuttings placed in the shade, partial-shade, or direct light? Thanks, and best of luck with your most recent batch.
