I got curious how the leaf cuttings are doing. The one with the very short petiole..not doing good..am not even sure if it will work.
But the other three seems more promising:Main leaves are lighter in color now. I can see a roundish small bump, so it dries out the tip end, and seems to gather all of what is left of the leaf towards that forming bump. But it is still very young..will check it out again in another month.
